GENERAL CONSIDERATIONS

MECHANICAL CONSIDERATIONS

The quality and accuracy of flow, level, or pressure measurement depends largely on the proper installation of the transmitter and its associated impulse piping and valves. For flow measurement, proper installation of the primary measuring element is also critical to the accuracy of the measurement. Transmitter installation should minimize the effects of temperature gradients and fluctuations, and avoid vibration and shock during normal operation. Take care when designing the measurement to minimize the error caused by incorrect installation.

This section contains information you should consider when preparing to mount the transmitter. Read this section carefully before proceeding to the mechanical installation procedure.

Rosemount 1152 Transmitters must be mounted with an optional mounting bracket or directly mounted to a rigid support. Proper installation is mandatory to assure seismic qualification per IEEE Std 344-1975.

Two mounting bracket options are available with the transmitter: a panel mount or a 2-inch pipe mount. Figure 2-2 on page 2-5 shows the qualified mounting configuration for both the panel and pipe mount options.

Orientation with respect to gravity is not critical. For maximum accuracy, however, if the transmitter is mounted so the flanges are horizontal, rezero the transmitter calibration to cancel the liquid head effect caused by the difference in height of the process connections.

Process Connections Process tubing installation must prevent any added mechanical stress on the

transmitter under seismic disturbances. This may be done by using stress-relief loops in the process tubing or by separately supporting the process tubing close to the transmitter.

Process connections on the transmitter flanges are sealant when making connections. Valve seats or plugs should also be sealed with thread sealant. Torque to 200 in-lbs (22.4 N-m).

The user assumes responsibility for qualifying interfaces.

If the drain/vent valves must be opened to bleed the process lines, torque to

7.5 ft-lb (10.2 N-m) when closing.

Proper location of the transmitter with respect to the process tubing depends on process parameters. Consider the following in determining the best location:

• Keep hot or corrosive process fluids from contacting the transmitter.

• Prevent sediment from depositing in the impulse tubing.

• Keep impulse tubing as short as possible.

• Ambient temperature gradients and fluctuations can result in erroneous transmitter readings.

• For differential transmitters, balance the liquid head on both legs of the impulse tubing.

• For liquid flow or pressure measurements, make taps to the side of the line to avoid sediment deposits, and mount the transmitter beside or below the taps so that gases vent into the process line (see Figure 2-3 on page 2-6).

• For gas flow or pressure measurements, make the taps on the top or side of the line and mount the transmitter beside or above the taps so that liquid drains into the process line (see Figure 2-3 on page 2-6).

• For steam flow or pressure measurements, make taps to the side of the line, and mount the transmitter below the taps so the impulse tubing stays filled with condensate (see Figure 2-3 on page 2-6).

• For steam service, fill lines with water to prevent steam from contacting the transmitter. Condensate chambers are not necessary since the volumetric displacement of the transmitter is negligible.

¼–18 NPT. Use thread

/4 - 18 NPT connection

2-2

The piping between the process and the transmitter must transfer the pressure measured at the process taps to the transmitter. Possible sources of error in this pressure transfer are:

•Leaks

• Friction loss (particularly if purging is used)

• Trapped gas in a liquid line or trapped liquid in a gas line (head error)

• Temperature-induced density variation between legs (head error), for differential transmitters

Reference Manual

00809-0100-4235, Rev BA April 2007

Rosemount 1152

To minimize the possibility of errors, take the following precautions:

• Make impulse tubing as short as possible.

• Slope tubing at least one inch per foot up toward the process connections for liquid and steam.

• Slope tubing at least one inch per foot down toward the process connections for gas.

• Avoid high points in liquid lines and low points in gas lines.

• Use impulse tubing of sufficient diameter to avoid friction effects.

• Ensure that all gas is vented from liquid tubing legs.

• Ensure that the impulse tubing is of adequate strength to be compatible with anticipated pressure.

For differential transmitters, consider the following:

• Keep both impulse legs at the same temperature.

• When sealing fluid is used, fill both piping legs to the same level.

• When purging is used, make the purge connection close to the process taps and purge through equal lengths of the same size tubing. Avoid purging through the transmitter.

Use a qualified conduit seal at the conduit entry to prevent moisture from accumulating in the terminal side of the housing during accident conditions. To prevent the conduit from adding mechanical stress to the transmitter during seismic disturbances, use flexible conduit or support the conduit near the transmitter. Install the conduit seal in accordance with the manufacturer’s instructions or use the procedure on page 2-8.

ELECTRICAL CONSIDERATIONS

This section contains information that you should consider when preparing to make electrical connections to the transmitter. Read this section carefully before proceeding to the electrical installation.

The Rosemount 1152 Pressure Transmitter provides a 4–20 or 10–50 mA signal when connected to a suitable dc power source. Figure 2-4 on page 2-7 shows a typical signal loop consisting of a transmitter, a power supply, and various receivers (controller, indicator, computer, etc.). With 4–20 mA output electronics, the power supply must supply at least 12 volts to the transmitter terminals at 30 mA (overscale) signal, or the maximum output current required for proper system operation. With 10–50 mA output electronics, the power supply must provide 30 volts minimum to the transmitter terminals at 90 mA (overscale) signal, or the maximum output current required for proper system operation. Any power supply ripple appears in the output load. The supply voltage versus load limitation relationship is shown in Figure 2-5 on page 2-7. The load is the sum of the resistance of the signal leads and the load resistance of the receivers.

Signal wiring need not be shielded, but twisted pairs yield the best results. In electrically noisy environments, shielded cable should be used for best results. Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. Signal wiring may be ungrounded (floating) or grounded at any place in the signal loop. The transmitter case may be grounded or ungrounded.

The capacitance sensing element uses alternating current to generate a capacitance signal. This alternating current is developed in an oscillator circuit with a frequency of 32,000 ± 10,000 Hz. This 32,000 Hz signal is capacitor-coupled to the transmitter case ground through the sensing element. Because of this coupling, a voltage may be imposed across the load, depending on choice of grounding.

This impressed voltage, which is seen as high frequency noise, has no effect on most instruments. Computers with short sampling times in a circuit where the negative transmitter terminal is grounded detect a significant noise signal. Filter this signal out by using a large capacitor (1

µf) or a 32,000 Hz LC filter

across the load. Signal loops grounded at any other point are negligibly affected by this noise and do not need filtering.

Span Adjustment (A and D Output)

Zero Adjustment (A and D Output)

Calibration Procedure— Zero and Span Adjustment (A and D Output)

The span on any Rosemount 1152 Transmitter is continuously adjustable to allow calibration anywhere between maximum span and

/6 of maximum span. For example, the span on a Range Code 4 transmitter can be continuously adjusted between 0–25 and 0–150 inH

Zero adjustments are limited as follows:

Rosemount 1152DP, Ranges 3, 4, and 5: 150 percent of calibrated span suppression or elevation.

Rosemount 1152DP, Ranges 6, 7, and 8: 50 percent of calibrated span suppression or elevation.

Rosemount 1152HP, Ranges 4 and 5: 150 percent of calibrated span suppression or elevation.

Rosemount 1152HP, Ranges 6 and 7: 50 percent of calibrated span suppression or elevation.

Rosemount 1152GP, all ranges: 100 percent of calibrated span suppression; to 0.5 psia elevation for compound ranges.

Rosemount 1152AP, all ranges: 100 percent of calibrated span suppression.

The transmitter may be calibrated to cross zero (e.g., –25 to 25 inH

O), but

this may result in a slight loss of linearity. A further limitation on zero adjustment is that the top of the span may not exceed the upper range limit.

NOTE

The Rosemount 1152 Pressure Transmitter contains electronic circuit boards which may be static sensitive.

NOTE

Covers need not be removed for zero and span adjustment.

3-2

The zero adjustment has very little effect on the span. Span adjustment may have a slight effect on zero and has a noticeable effect when zero is elevated or suppressed because the span is rotated about a point on the zero differential. The following example for a Rosemount 1152DP, Range 4, shows the proper sequence for changing a 25 to 125 inH of 25 inH –25 inH

O, span of 100 inH2O) to a range of –75 to

O (elevated zero of 75 inH2O, span of 50 inH2O).

1. Turn the zero adjustment to bring the range from 25–125 inH 100 inH

2. Turn the span adjustment to bring the range from 0–100 inH 50 inH

3. Turn the zero adjustment to bring the range from 0–50 inH –75 to –25 inH

4. Recheck full scale and zero and adjust if necessary.

NOTE

There is some mechanical backlash in the zero and span adjustments, so there will be a dead band when direction of adjustment is changed. The simplest correction, if the desired setting is overshot, is purposely overshooting a larger amount before reversing the direction of adjustment.

NOTE

On Range Codes 6, 7, 8, 9, and 10, the span adjustment has a significant effect on zero. This effect becomes increasingly more pronounced as span is decreased. The span effect on zero is great enough in some instances to cause a decrease in full-scale output with an increase in span.

In addition to the span and zero adjustments, there is a linearity adjustment located inside the transmitter, accessible through the amplifier board. Linearity is factory adjusted for optimum performance over the calibrated range of the instrument and is not normally adjusted in the field. To maximize linearity over some particular range, use the linearity adjustment. It is necessary to readjust span after adjusting linearity. Figure 3-1 on page 3-3 and Figure 3-2 on page 3-4 show the location of the linearity adjustment.

The stepped variable time-constant amplifier board is designed to permit dampening out of rapid pulsations in the pressure source by selecting one of four time constant settings. The available settings provide time-constant values (63.2 percent of total response) between 0.2 seconds

(1)

and 2.0 seconds. These time-constants are selected by manually setting a four-position rotary switch located on the amplifier board. The switch positions are labeled 1, 2, 3, and 4 which correspond to time-constant values of 0.2,

0.5, 1.0, and 2.0 seconds, respectively. The tolerance of these values is ±20 percent. Figure 3-2 on page 3-4 shows the four-position rotary switch.

Select the shortest possible time constant setting. For example, if the 0.5 second time constant is sufficient to dampen out the undesired pulsations, then do not use a longer time constant.

Since transmitter accuracy is not influenced by the time constant setting, the transmitter can be calibrated with the switch in any one of the four positions. However, position 1 gives the fastest time response during calibration. The switch can be reset later to any other position without further adjustments.

(1) The actual minimum time constant (at 100 °F) is range dependent as follows: 0.3 seconds

nominal (Range Code 3); 0.2 seconds nominal (Range Codes 4 and 5); 0.1 seconds nominal (Range Codes 6, 7, 8, 9, and 10).

CALIBRATION (E, N, AND L OUTPUT)

Span Adjustment (E, N, and L Output)

Zero Adjustment (E, N, and L Output)

Rosemount 1152DP, HP, GP, and AP Transmitters are factory calibrated to the range shown on the nameplate. This range may be changed within the limits of the transmitter. Zero may also be adjusted to elevate (for all models except Rosemount 1152AP) or suppress (for all models). The span and zero adjustments are external and located under the nameplate.

The span on any Rosemount 1152 Transmitter is continuously adjustable to allow calibration anywhere between maximum span and

/6 of maximum span. For example, the span on a Range Code 4 transmitter can be continuously adjusted between 0–25 inH

O and 0–150 inH2O.

The zero on a Rosemount 1152 Transmitter with the E, N, or L output can be adjusted for up to 500 percent of span suppression or 600 percent of span elevation (see Figure 3-3 on page 3-5 for E or N output).

The zero may be elevated or suppressed to these extremes with the limitation that no applied pressure within the calibrated range exceeds the full-range pressure limit. For example, a Range Code 4 transmitter cannot be calibrated for 150 to 200 inH inH

O exceeds the 150 inH2O full-range pressure limit of Range Code 4.

To achieve large amounts of elevation or suppression, the E output electronics have a switch and N output electronics have either a switch or three turrets on the component side of the amplifier board (refer to Electrical Housing Disassembly on page 5-4 and to Figure 5-2 on page 5-6 to locate the amplifier board). The slide switch, shown in Figure 3-4 on page 3-6, has three positions. The middle position allows moderate amounts of elevation or suppression. To achieve large elevations or suppressions, move this switch to the “elevate zero” or “suppress zero” position. If the amplifier board has three turrets, shown in Figure 3-5 on page 3-6, large elevations or suppressions are achieved by connecting a jumper wire between the middle terminal and the terminal marked “EZ” (elevation) or “SZ” (suppression).

To make large elevation or suppression adjustments using the L output electronics (10–50 mA), it is necessary to move a jumper pin assembly on the component side of the amplifier board. The jumper pin has three positions, as shown in Figure 3-4 on page 3-6. The middle position allows normal levels of elevation or suppression. To make larger adjustments, move the jumper to the Elevate Zero or Suppress Zero position (marked EZ and SZ accordingly).

NOTE

The Rosemount 1152 Pressure Transmitter contains electronic circuit boards which may be static sensitive.

NOTE

Covers need not be removed for zero and span adjustment.

The zero and span adjustment screws are accessible externally and are located behind the nameplate on the side of the electronics housing (see Figure 3-6). The transmitter output increases with clockwise rotation of the adjustment screws.

The zero adjustment has very little effect on the span. The span adjustment, however, does affect the zero. The effect of interaction is more apparent with suppression or elevation. The span adjustment changes the zero output and the full-scale output by approximately the same percentage. Therefore, it is best to calibrate the transmitter from zero to the desired span and finish the calibration by adjusting the zero screw to achieve the desired elevation or suppression.

3. Adjust the zero screw to bring the output, with 0 inH 4 mA. The transmitter calibration should now be very close to 0 to 50 inH

4. Check full-span output and fine tune the span and zero adjustment, if required. Remember that zero adjustments do not affect span, but span adjustments do affect zero. Adjusting the span screw affects the

zero

/5 as much as it affects the span. To compensate for this effect, simply overadjust by 25 percent. For example, if, after completing step 3, the transmitter output reads 19.900 mA at 50 inH span potentiometer until the output (at 50 inH

O) reads 20.025 mA.

O, turn the

19.900 + (20.000 – 19.900) ⫻ 1.25 =

19.900 + 0.125 = 20.025.

Since the span adjustment affects zero

/5 as much as the span, the

0.125 mA increase in span causes a 0.025 mA increase in zero. Therefore, turn the zero adjustment (at 50 inH

O) until the output

reads 20.000 mA. The unit should now be calibrated for 0 to 50 inH

5. Zero elevation/suppression: Elevate the zero. Turn the zero screw until the output reads 4 mA with –75 inH the transmitter (applying 75 inH

O to the low side of the transmitter

Linearity Adjustment (E, N, and L Output)

In addition to the span and zero adjustments, there is a linearity adjustment located on the solder side of the amplifier board (see Figure 3-7). Linearity is factory calibrated for optimum performance over the calibrated range of the instrument and is not normally adjusted in the field. If it is desired to maximize linearity over some particular range, use the following procedure:

1. Apply mid-range pressure and note the error between theoretical and actual output signals.

2. Apply full-scale pressure. Multiply the error noted in step 1 by six and by the range down factor.

Maximum Allowable Span

3. Add the result to the full-scale output for negative errors, or subtract the result from the full-scale output for positive errors, by adjusting the linearity trimmer (see Figure 3-7). Example: At 4-to-1 range down, the midscale point is low by 0.05 mA. Therefore, adjust the “Linearity” trimmer until full-scale output increases by (0.05 mA ⫻ 6 ⫻ 4) = 1.2 mA.

Calibrated Span

Damping Adjustment (E, N, and L Output)

The E, N, and L output amplifier boards are designed to permit damping of rapid pulsations in the pressure source by adjusting the trimmer marked “damping” located on the solder side of the amplifier board. The settings available provide time-constant values up to 1.67 seconds nominal. The instrument is calibrated and shipped with this adjustment set at the counterclockwise stop (fastest setting). It is best to set the damping to the shortest possible time-constant setting. Since transmitter calibration is not affected by the damping setting, you may adjust the damping with the transmitter installed on the process. Turn the damping adjustment clockwise until the desired damping is obtained. Figure 3-7 on page 3-9 shows the location of the damping adjustment.

The damping potentiometer has positive stops at both ends. Forcing the potentiometer beyond the stops may cause permanent damage.

---------------------------------------------------------- - 0.73 % span= 400 inH

9. Repeat step 5 with the result of step 8:

0.73% 16 mA× 0.117 mA=

10. Add the mA correction to the ideal full-scale output (20 mA). This is the corrected ideal full-scale output.

20.00 mA 0.117 mA+ 20.117 mA=

11. Readjust the zero and span adjustments for corrected output.

There is an uncertainty of ±0.25 percent of input reading per 1,000 psi (±0.5% input reading per 1,000 psi for Range Code 3) associated with the span correction.

Zero Zero shift with static pressure is not systematic. However, if the calibrated

range includes zero differential pressure, the effect can be trimmed out after installation and with the unit at operating pressure.

Equalize pressure to both process connections and turn the zero adjustment until the ideal output at zero differential input is observed. Do not readjust the span potentiometer.

If, however, the transmitter does not include zero differential pressure within its calibrated span, the zero effect or zero correction can be determined before the unit is suppressed or elevated to eliminate the zero effect after correcting for the span effect.

The following procedure illustrates how to eliminate the zero effect for a non-zero differential pressure-based calibration. The example uses a Range Code 5 with a 4–20 mA output calibrated from 100 to 500 inH2O with 1,200 psi static line pressure.

1. Using standard calibration procedures, calibrate the unit to the required span, with the 4 mA or zero point corresponding to zero differential pressure:

4 mA at 0 inH2O and 20 mA at 400 inH2O

2. Apply static pressure to both high and low process connections with zero differential pressure across the transmitter, and note the zero correction (zero shift). For example, if the output reads 4.006 mA, the zero correction is calculated as:

4.00 mA – 4.006 mA = –0.006 mA Note the sign associated with this correction, as this result will be added when determining the final, ideal transmitter output.

3. Remove static pressure and correct for the span effect as outlined in the span correction procedure. Calibrate the unit to the calculated output values. If, for example, the span correction procedure yielded

4.029 mA and 20.144 mA, calibrate the unit for:

4.029 mA at 100 inH2O

20.144 mA at 500 inH2O

4. Add the zero correction found in step 2 (–0.006 mA) to the ideal zero point value calculated in step 3.

4.029 mA + (–0.006 mA) = 4.023 mA

5. To eliminate the zero effect, readjust the zero potentiometer so that the output reads the ideal zero point calculated in step 4 (do not readjust the span potentiometer). Note that all the calibration points shift the same amount toward the correct reading. The example output is now 4.023 mA at 100 inH2O.

The transmitter output will now be 4–20 mA over its calibrated span when the unit is operated at 1,200 psi static line pressure.

The ␦-Cell Sensor Process pressure is transmitted through an isolating diaphragm and silicone

oil fill fluid to a sensing diaphragm in the center of the ␦-cell. The reference pressure is transmitted in like manner to the other side of the sensing diaphragm.

The position of the sensing diaphragm is detected by the capacitance plates on both sides of the sensing diaphragm. The capacitance between the sensing diaphragm and either capacitor plate is approximately 150 pf. The sensor is driven through transformer windings by an oscillator at roughly 32 kHz and 30 V

LINEARITY ADJUSTMENT

The oscillator driving current, I transformer windings) is kept a constant by an integrated circuit amplifier.

The dc current through a third transformer winding is a current directly proportional to pressure; i.e.,

The diode bridge and span temperature compensating thermistor are located inside the sensor module. The effect of the thermistor is controlled by resistors located in the electronics housing.

Linearity is adjusted by a variable-resistance network, capacitor, and diodes. The currents generated through this part of the circuit are summed into the inputs of the oscillator control circuit. This provides a programmed correction that raises the oscillator peak-to-peak voltage to compensate for first-order nonlinearity of capacitance as a function of pressure.

OSCILLATOR The oscillator frequency is determined by the capacitance of the sensing

element and the inductance of the transformer windings.

The sensing element capacitance is variable. Therefore, the frequency is variable about a nominal value of 32 kHz.

An integrated circuit amplifier acts as a feedback control circuit and controls the oscillator drive voltage such that:

VOLTAGE REGULATOR The transmitter uses a zener diode, transistor, and several resistors to provide

a constant voltage of 6.4 V dc for the reference and 7 V dc for the oscillator.

ZERO AND SPAN ADJUSTMENTS

Zero adjustment components consist of a potentiometer and resistor that develop a separate adjustable current sum with the sensor current. The coarse zero switch switches resistors into the circuit as needed.

Span adjustment is performed with a potentiometer that determines the amount of loop current that is sensed and fed back to the current control amplifier.

CURRENT CONTROLS The current control amplifier consists of an integrated circuit, two transistors,

and associated components. The integrated circuit reference voltage is established at the junction of a resistor network. The current control amplifier drives the current control to a level such that the current detector feeds back a signal equal to the sum of the zero current and the variable sensor current.

CURRENT LIMIT The current limiter prevents excessively high output currents in case of

overpressure. Maximum output with the 4–20 mA output is limited to 30 mA. Maximum output with the 10–50 mA output is limited to 90 mA.

REVERSE POLARITY

OVERVIEW This section outlines a technique for checking out the components, a method

for disassembly and reassembly, and a troubleshooting guide.

NOTE

Maintenance of traceability of any replacement parts is the responsibility of the user (see the “Important Notice” on page 6-10 and the Important Notice at the beginning of this manual, preceding the Table of Contents).

The Rosemount 1152 has no moving parts and requires a minimum of scheduled maintenance. Calibration procedures for range adjustment are outlined in Section 3: Calibration. A calibration check should be conducted after inadvertent exposure to overpressure, unless your plant considers this factor separately in the plant error analysis.

Test terminals are available for in-process checks. For further checks, the transmitter can be separated into three active physical components: the sensing module, the amplifier board, and the calibration board.

An exploded view drawing is provided in Figure 5-2 on page 5-6. In the following procedures, numbers in parentheses refer to item numbers in the exploded view.

SAFETY MESSAGES Instructions and procedures in this section may require special precautions to

ensure the safety of the people performing the operations. Information that raises potential safety issues is indicated by a warning message. The following warning messages appear in this section.

Use only the procedures and new parts specifically referenced in this manual to ensure specification performance and certification compliance. Unauthorized procedures or parts can render the instrument dangerous to life, limb, or property.

Process O-rings may retain some process fluid after disassembly of process flanges. If this fluid is determined to be contaminated, take appropriate safety measures.

April 2007

TEST TERMIN A LS The test terminals are connected across a diode through which the loop

signal current passes. The indicating meter or test equipment shunts the diode when connected to the test terminals. As long as the voltage across the terminals is kept below the diode threshold voltage, no current passes through the diode. To ensure that there is no current leakage through the diode when making a test reading or when connecting an indicating meter, the resistance of the test connection or meter should not exceed 10 Ω for the 4– 20 mA output or 4 Ω for the 10–50 mA output.

BOARD CHECKOUT NOTE

Numbers in parentheses refer to item numbers in Figure 5-2 on page 5-6.

SENSING MODULE CHECKOUT

NOTE

The Rosemount 1152 Pressure Transmitter contains electronic circuit boards, which may be static sensitive.

You can easily check the printed circuit boards (11 and 13) for a malfunction by substituting spare boards into the circuit. If this procedure turns up a malfunctioning board, return the defective board to Rosemount Nuclear Instruments, Inc. for replacement. Because of parts traceability, qualification becomes the responsibility of the customer in the event of unauthorized board repairs.

NOTE

When replacing either the A or D output amplifier or calibration board, both boards must be replaced with N output amplifier and calibration boards. When replacing the E output amplifier or calibration board, the boards must be replaced with an N output amplifier or calibration board. Both boards do not need to be replaced on the E output.

NOTE

Numbers in parentheses refer to item numbers in Figure 5-2 on page 5-6.

The sensing module (24) is not field-repairable and must be replaced if defective. If no defect such as a punctured isolating diaphragm or loss of fill fluid is observed, check the sensing module in the following manner:

5-2

1. Disengage the header assembly board (10) as described in “Electrical Housing Disassembly” on page 5-4. You need not remove the sensing module from the electrical housing for checkout.

2. Jump connections 1 and 2 on the header assembly board (see Figure 5-1).

NOTE

Carefully remove the O-rings (23) from the cell if they do not come off when the flange is removed. Do not pry the O-ring from its seat as damage to the isolating diaphragm may occur.

3. Clean isolating diaphragms with a soft cloth and a mild cleaning solution. Do not use any chlorine or acid solutions to clean the diaphragms. Rinse the diaphragms with distilled water.

Electrical Housing Disassembly

1. The signal terminals and the test terminals are accessible by unscrewing the cover (1) on the terminal side. This compartment is identified as “Terminal Side” on the nameplate. The terminals are permanently attached to the housing and must not be removed.

2. Circuit boards are located in a separate compartment identified as “Circuit Side” on the nameplate. Remove power from the transmitter before removing the circuit cover. Unscrew the cover (1) on the circuit side to access the circuit boards. A special cover wrench (RMT P/N 01153-0382-0001) is available from Rosemount to remove and replace the housing covers.

3. E, N, and L Output: Unplug the amplifier board (13) after removing the three holding screws (14). The L output board has an additional captive screw that should be removed last.

4. The header assembly board (10) is permanently attached to the sensor module (24) and contains the temperature-compensating resistors. Carefully pull this board off the bayonet pins. Rotate the board 180° about the axis formed by the connecting leads. This allows access to the calibration board (11).

5. Disconnect the calibration board (11) by removing the three standoffs (12) and aligning the zero and span adjust screws so that their slots are perpendicular to the board. Remove the board by grasping the interface pin and pulling outward.

A and D Output: Unplug the amplifier board (13) after removing 3 holding screws (14) and loosening the heat sink screw, which is captive to the board. Remove the board by inserting a #6-32 screw in the rivnut on the board. The header assembly board (10) is permanently attached to the sensor module (24) and contains the temperature compensating resistors. Carefully pull this board off the bayonet pins by inserting a #6-32 screw into the rivnut on the board. Rotate the board 180° about the axis formed by the connecting leads. This allows access to the calibration board (11). Disconnect the calibration board by removing the three standoffs (12) and aligning the zero and span adjust screws so that their slots are perpendicular to the board. Remove the board by inserting a #6-32 screw in the rivnut on the board.

6. If replacement of the zero and span adjustment screws (4) is necessary, remove the nameplate (8) and detach the snap rings (6) inside the housing.

Electrical Housing Assembly

1. Run the lock nut down to the base of the sensor module threads.

2. Apply a heavy, continuous bead (about 580-PST sealant (RMT P/N 01153-0329-0001) around the top sensor module threads.

3. Insert the header assembly board (10) through the hole in the bottom of the electronics housing.

4. Screw the sensor module (24) into the electrical housing (3), ensuring that five full threads are engaged. Be careful not to damage or twist the sensor module leads. Turn the header board to avoid twisting wires.

5. Align the sensor module with the high and low pressure sides oriented per Figure 2-1 on page 2-4, as applicable. Alternately, tighten the module one-half turn further to reverse the orientation of the module about the electronics housing.

6. Tighten the lock nut (17) to 35 ft-lb (47.5 N-m) torque.

7. Wipe off excess sealant.

8. Place the assembled unit in an oven at 200 ± 5 °F (93 ± 3 °C) for 12 hours to cure the sealant.

1. Replace the zero and span adjustment screw O-rings (5) whenever you remove the zero or span adjustment screws (4). Lightly grease the O-rings with Dow Corning 55 Silicone O-ring Grease (RMT P/N 01153-0248-0001 or P/N 01153-0053-0001). Reinstall the adjustment screws and secure with snap rings (6).

2. Align the zero and span adjustment screws with the potentiometer stems on the calibration board (11) and push the calibration board onto the bayonet pins.

3. Secure the calibration board with the three standoffs (12). The upper-right-hand standoff grounds the electronics to the case and must be firmly in place.

4. Slide the header assembly board (10) onto the bayonet pins with the component side toward the pins. Slide excess wire behind the calibration board, taking care to avoid kinks.

5. Push the amplifier board (13) onto the bayonet pins. Connect the heat sink screw (A, D, and L outputs only) and secure the amplifier board with the three holding screws (14).

6. Carefully replace the cover (1) and tighten to 16.5 ft-lb (22.4 N-m) (see “Preliminary” on page 5-5).

7. Replace the nameplate (8) and attach with two nameplate screws (7).

3. Carefully place the flange (25 or 27) as shown in the exploded view. Take care not to disturb the O-rings or damage the diaphragms.

4. On differential units, repeat steps 2 and 3 for the low side (“L”) of the sensor module. For gage units, repeat step 3 for the low side (“L”) of the sensor module.

5. Keeping the flanges parallel to each other and to the module faces, insert the four bolts (26) (and washers on Range Codes 9 and 10) and finger-tighten the nuts (15). Each spare parts kit contains the correct number of nuts, bolts, and washers for the specific transmitter range code it is designated for. Due to recent consolidation of parts kits, the bolt length and quantity of washers required may differ from existing transmitter assemblies and/or parts kits. Verify by part number that the appropriate spare parts kit is used for the transmitter range code being re-assembled. Contact Rosemount Nuclear Instruments, Inc. if there are any questions.

6. Evenly seat the flanges on the sensor housing, using a hand torque wrench. See Figure 5-2 on page 5-6 to identify the bolts.

7. Alternately tighten bolts A and B to 10 ft-lb (14 N-m) torque.

8. Alternately tighten bolts C and D to 10 ft-lb (14 N-m) torque.

9. Check torque on A and B.

10. Check torque on C and D.

11. Repeat steps 7–10 at 15 ft-lb (20 N-m) torque, at 20 ft-lb (27 N-m) torque, and at 25 ft-lb (34 N-m) torque until all bolts are torqued to 25 ft-lb (34 N-m).

12. Expose Range Code 3 transmitters to two temperature cycles over the expected operating temperature range before calibration.

(1) Rosemount recommends one spare part or kit for every 25 transmitters in Category “A”, one spare part or kit for every 50 transmitters in Category “B”, and

one spare part or kit for every 5 transmitters in Category “C”. (2) Current standard configuration on transmitters assembled at factory. (3) Each spare parts kit contains the correct number of nuts, bolts, and washers for the specific transmitter range code it is designated for. Due to recent

consolidation of parts kits, the bolt length and quantity of washers required may differ from the existing transmitter assemblies and/or parts kits. Verify by

part number that the appropriate spare parts kit is used for the transmitter range code being re-assembled. Contact Rosemount Nuclear Instruments, Inc. if

there are any questions. NOTE: Rosemount 1152 spare parts not hydrostatic tested or nuclear cleaned.

SPARE PARTS SHELF LIFE

Store all spare transmitters and spare component parts in accordance with ANSI N45.2.2 level B.

Lubricants and sealants: The data of the end of shelf life (use by date) is provided with the lubricants and/or sealant at the time of shipment. The product has a minimum of six months shelf life at the time of shipment.

All other parts: Shelf life is not applicable.

IMPORTANT NOTICE There are factors to consider concerning maintenance of qualification and

traceability during on-site instrument repair because of the nuclear use intended for these parts. Rosemount Nuclear Instruments, Inc. rigidly controlled the original assembly of the instrument to ensure that the specifications were met. Since we are not installing the replacement parts in the instruments, Rosemount Nuclear Instruments, Inc. is unable to ensure that the specifications are being satisfied. This responsibility is shifted to the user. The integrity of the instrument as originally assembled is broken.

Replacing parts has ramifications under 10CFR21, for which the user is responsible. These same regulations additionally mandate a component

traceability program, which the user must undertake for the replacement parts. In view of this, and in order to maintain the qualification of the product, the user must ensure that all replacement parts are installed in accordance with the Rosemount Nuclear Instruments, Inc. approved installation and recalibration procedures herein.

Notes

1. Rosemount 1152 spare parts are not hydrostatic tested or nuclear cleaned.

2. Part numbers shown may differ from those currently supplied. The part numbers shown are current at the time of printing of this manual, but may be revised in the future. Parts provided are compatible and interchangeable with those listed on your order as to the form, fit, and function of the part required. Please adjust your needs accordingly.
