GENERAL 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 temperature fluctuations, and avoid vibration and shock during normal operation. Take care when designing the measurement to minimize the error caused by incorrect installation. The temperature of the transmitter ambient environment affects the qualified life of the transmitter. (See Figure 2-1.)

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

1154-0293A

mechanical installation procedure.

Mount the Rosemount 1154 Series H transmitter to a rigid support (i.e., one with a fundamental mechanical resonant frequency of 40 Hz or greater). A mounting bracket included with the transmitter facilitates panel mounting. Figure 2-4 on page 2-7 shows the qualified mounting configurations. The transmitter was seismic tested and qualified with the bracket mounted with

/8 in. diameter bolts. Orientation with respect to gravity is not critical to

four qualification. However, if the transmitter is mounted with the flanges in a horizontal position, zero the transmitter to cancel the liquid head effect caused by the difference in height of the process connections.

If the transmitter is mounted to a non rigid panel, ensure that seismic input to the mounting bracket does not exceed qualification levels given in Rosemount Report D8700096.

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 near the transmitter.

The process connections to the transmitter flanges were qualified with tubing using Swagelok

compression fittings. For options using 1/4–18 NPT

connections, the user assumes responsibility for qualifying the interface.

/8 in.

Transmitters with Flange Options A or H are shipped with Swagelok fittings for process connections. Included are front ferrule, rear ferrule, and nut. Ensure the fittings are placed on the tubing with the orientation and relative position shown in Detail A in Figure 2-5 on page 2-8.

Reference Manual

00809-0100-4631, Rev BA April 2007

Rosemount 1154 Series H

Process tubing used is 3/8 in. outside diameter, and of suitable thickness for the pressure involved.

The Swagelok tube fittings are shipped completely assembled for immediate use. Do not disassemble them before use; doing so may contaminate the fittings and result in leaks. Insert the tubing into the Swagelok tube fitting, making sure that the tubing rests firmly on the shoulder of the fitting and that the nut is finger tight. Tighten the nut one-and-one-quarter turns past finger tight to prepare the transmitter for use. Do not overtighten.

The connections can be loosened and re-tightened 20–30 times without compromising the leak-proof seal. To reconnect, insert the tubing with pre-swaged ferrules into the fitting until the front ferrule sits in the fitting. Tighten the nut by hand, then rotate one-quarter turn more or to the original one-and-one-quarter tight position. Then snug it slightly with a wrench. For more information regarding the use of Swagelok tube fittings, refer to:

Fittings Catalog MS-01-140 “Gaugeable Tube Fittings and Adapter Fittings” www.swagelok.com

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

/2 ft-lb (10 N-m) when closing.

Proper location of the transmitter with respect to the process tubing depends on various process parameters. When determining the best location, consider the following:

• Keep hot or corrosive fluids from contacting the transmitter.

• Prevent sediment from depositing in the impulse tubing.

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

• Keep impulse tubing as short as possible.

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

• For liquid flow or pressure measurements, make taps on the side of the line to avoid sediment deposits and mount the transmitter beside or below the taps so gases vent into the process line (see Figure 2-6 on page 2-9).

• For gas flow or pressure measurements, make taps on the top or side of the line and mount the transmitter beside or above the taps so liquid drains into the process line (see Figure 2-6 on page 2-9).

• For steam flow or pressure measurements, make taps on the side of the line and mount the transmitter below the taps so the impulse tubing stays filled with condensate (see Figure 2-6 on page 2-9).

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

2-3

Rosemount 1154 Series H

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

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 impulse tubing is of adequate strength to be compatible with anticipated pressures.

Reference Manual

00809-0100-4631, Rev BA

April 2007

For differential transmitters, also consider the following:

• Keep both impulse legs at the same temperature.

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

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

Conduit The conduit connection to the transmitter is

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 2-9.

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 procedures.

The Rosemount 1154 Series H Pressure Transmitter provides a 4–20 mA signal when connected to a suitable dc power source. Figure 2-2 on page 2-5 shows a typical signal loop consisting of transmitter, power supply, and various receivers (controller, indicator, computer, etc.). The power supply must supply 12 volts minimum to the transmitter terminals at 30 mA (overscale) signal, or the maximum output current required for proper system operation. Any power supply ripple will be seen in the output load. The supply voltage versus load limitation relationship is shown in Figure 2-3 on page 2-5. See qualification report D8700096 for details. 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 should be used for 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, nor 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 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, will have no effect on most instruments. Computers with short sampling times in a circuit where the negative transmitter terminal is grounded, will detect a significant noise signal. Filter this noise with a large capacitor (1 µf) or by using 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.

INSTALLATION PROCEDURES

Installation consists of mounting the transmitter and conduit and making electrical connections. Following are procedures for each operation.

Mechanical Transmitter

Be careful not to break the neck seal between the sensor module and the electronics housing.

The threaded interface between the sensor module and the electronics housing is hermetically sealed before shipment. The integrity of this seal is necessary for the safe operation of the transmitter during accident conditions. If the seal is broken, reseal it according to “Connecting Electrical Housing to Module Shroud” on page 5-4.

1. Mount bracket to a panel or other flat surface as shown in Figure 2-4

on page 2-7. Use four SAE grade 2, AISI 316 SST, or ASTM A193 grade 8M class 1 bolts were used during qualification testing. Torque each bolt to 33.5 ft-lb (45.4 N-m).

2. Attach the transmitter to the mounting bracket, as shown in Figure 2-4

Span Adjustment Zero Adjustment

• Calibration Procedures

Zero and Span Adjustment Linearity Adjustment Damping Adjustment Correction for High Line Pressure

CALIBRATION The Rosemount 1154DH, HH, and SH 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 or suppress. The span and zero adjustments are external and located under the nameplate.

Span Adjustment The span on any Rosemount 1154 Series H Transmitter is continuously

adjustable to allow calibration anywhere between maximum span and maximum span. For example, the span on a Range Code 4 transmitter can be continuously adjusted between 0–150 inH 0–25 inH

O and

/6 of

Zero Adjustment The zero can be adjusted for up to 500 percent of span suppression or 600

percent of span elevation (see Figure 3-1).

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 inH 200 inH Code 4.

The transmitter may be calibrated to cross zero (e.g., –75 inH 75 inH

O to 200 inH2O (only 300 percent zero suppression) because the

O exceeds the 150 inH2O upper range pressure limit of a Range

O to

O), but this may result in a slight loss of linearity.

CALIBRATION PROCEDURE

Zero and Span Adjustment

NOTE

The Rosemount 1154 Series H 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. They are located behind the nameplate on the side of the electronics housing (see Figure 3-2). The output of the transmitter increases with clockwise rotation of the adjustment screws.

The zero adjustment screw has very little effect on the span. The span adjustment, however, does affect 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 0 to the desired span and finish the calibration by adjusting the zero screw to achieve the desired elevation or suppression.

4. Check full-scale output and fine tune the span and zero adjustment if required. Remember zero adjustments do not affect span, but span adjustments do affect zero predictably. Adjusting the span screw will affect the zero 1/5 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 read 19.900 mA at 50

Rosemount 1154 Series H

Since the span adjustment affects zero one-fifth 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 reads 20.000 mA. The unit should now be calibrated for 0 to 50 in H

To suppress zero, follow the same procedure, except connect the jumper wire between the middle terminal and the terminal marked “SZ” (see Figure 3-3, Detail C).

6. Recheck full scale and zero and fine tune if necessary.

NOTE

There is some mechanical backlash in the zero and span adjustments, so there is a dead band when you change the direction of adjustment. Because of the backlash, the simplest procedure, if the desired setting is overshot, is to intentionally overshoot a larger amount before reversing the direction of the adjustment.

Linearity Adjustment In addition to the span and zero adjustments, there is a linearity adjustment

located inside the transmitter on the amplifier board (see Figure 3-4 on page 3-6). Linearity is factory calibrated for optimum performance over the calibrated range of the instrument and is not normally adjusted in the field. If you want 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 signal.

2. Apply full-scale pressure. Multiply the error noted in Step 1 by six and by the following rangedown factor:

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 3-4). Example: At 4-to-1 rangedown 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.

Damping Adjustment Damping electronics are available as an option. Transmitters with standard

electronics can be retrofitted with the adjustable damping feature by changing out both the amplifier board (RMT P/N 01154-0021-0004) and the calibration board (RMT P/N 01154-0023-0002).

The damping adjustment permits damping of rapid pressure variations by adjusting the single-turn trim potentiometer located on the upper right-hand side of the amplifier board (see Figure 3-4). The available settings, when adjusted to the maximum position, provide time-constant values of at least 1.2 seconds for Range Code 4 and 0.8 seconds for Range Codes 5–9. Transmitters with the electronic damping option are calibrated and shipped with the adjustment set at the counterclockwise stop, which gives the minimum time-constant.

1154-0299B

Correction For High Line Pressure (Rosemount 1154DH and 1154HH only)

To adjust the damping, turn the damping adjustment potentiometer until the desired time-constant is obtained. It is best to set the damping to the shortest possible time-constant. Since transmitter calibration is not affected by the damping setting, you may adjust the damping with the transmitter installed on the process.

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

NOTE

If you remove either cover during the above procedures, replace the O-ring and torque the cover per the instructions given in Section 5: Maintenance and Troubleshooting of this manual. Spare cover O-rings are supplied with each transmitter.

If a differential transmitter is calibrated with the low side at ambient pressure but will be used at high line pressure, correct the span adjustment to compensate for the effect of static pressure on the unit. If zero is elevated or suppressed, also correct the zero adjustment. Correction factors, expressed in percent of differential pressure input at end points per 1,000 psi static pressure, are:

11. Readjust zero and span adjustments for corrected outputs:

3.964 mA at –100 inH

20.108 mA at 300 inH

There is an uncertainty of ±0.5 percent of input reading per 1,000 psi 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 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 calibration. The example uses a Range Code 5 calibrated from 100 to 500 inH

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

O with 1,200 psi static line pressure.

4 mA at 0 inH

O 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 is 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 inH

20.144 mA at 500 inH

4. Add the zero correction (–0.006 mA), found in Step 2, 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 the output reads the ideal zero point calculated in Step 4 (do not readjust the span potentiometer). Note that all the calibration points will shift the same amount toward the correct reading. The example output is now 4.023 mA at 100 inH

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

The block diagram in Figure 4-2 on page 4-3 illustrates the operation of the transmitter.

The Rosemount 1154 Series H Alphaline Pressure Transmitters have a variable capacitance sensing element, the -Cell (Figure 4-1 on page 4-2). Differential capacitance between the sensing diaphragm and the capacitor plates is converted electronically to a 2-wire 4–20 mA dc signal.

SIGNAL

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  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

DEMODULATOR The demodulator consists of a diode bridge that rectifies the ac signal from

the sensor cell to a dc signal.

The oscillator driving current, I

(the sum of the dc currents through two

transformer windings) is controlled to be 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 ADJUSTMENT

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 has a frequency 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 is used as a feedback control circuit and controls the oscillator drive voltage such that:

VOLTAGE REGULATOR The transmitter uses a zener diode, transistor, and 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 that sums with the sensor current. The coarse zero switch switches resistors into the circuit as needed.

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

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

and associated components. The IC 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 A current limiter prevents the output current from exceeding 30 mA in an

overpressure condition.

REVERSE POLARITY

A zener diode provides reverse polarity protection.

OVERVIEW This section contains 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 Important Notice on page 6-9 and Important Notice at the beginning of this manual, preceding the Table of Contents).

The Rosemount 1154 Series H 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 divided into three active physical components: the sensing module, the amplifier board, and the calibration board.

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.

TEST TERM IN ALS 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 leaking 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.

BOARD CHECKOUT NOTE

SPARE PARTS SHELF LIFE

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

Qualified transmitters, spare circuit boards, spare O-rings: The qualified life (as defined in Qualification Test Report D8700096) plus the shelf life is equal to the typical design life of the plant (40 years) when the ambient storage temperature is below 90 °F.

Lubricants and sealant: The date 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 Because of the nuclear use intended for these parts, there are factors to

consider concerning maintenance of qualification and traceability during on-site instrument repair. 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 calibration procedures herein.

1. Rosemount 1154 Series H spare parts are not hydrostatic tested nor 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.
