Rosemount 1154 Pressure Transmitters are designed for precision pressure measurements in nuclear applications requiring reliable performance and safety over a specified qualified life. These transmitters were generically tested to the IEEE Std 323-1974 and IEEE Std 344-1975 per the Qualification Test Report D8400102. The Rosemount 1154 has been qualification tested to environments typical of Pressurized Water Reactors (PWR) under accident conditions. Stringent quality control during the manufacturing process includes traceability of pressure retaining parts, special nuclear cleaning, and hydrostatic testing.

Rosemount 1154 Transmitters are uniquely built to Class 1E nuclear service while retaining the working concept and design parameters of the Rosemount 1151 Series that have become a standard of reliable service. Units are available in gage (G), differential (D), and high-line differential (H) configurations, with a variety of pressure range options, as shown in Table 6-1 on page 6-8. Figure 2-5 on page 2-7 shows dimensional drawings for the transmitters.

Installation Procedures Mechanical Electrical

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 ambient temperature of the transmitter environment affects the qualified life of the transmitter (see Figure 2-1).

MECHANICAL CONSIDERATIONS

Process Connections

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

Mount the Rosemount 1154 transmitter to a rigid support (a support 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 2-6 shows the qualified mounting configurations. The transmitter was seismic qualified with the bracket mounted with four 3/8-in. diameter bolts. Orientation with respect to gravity is not critical to 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, the user must ensure that seismic input to the mounting bracket does not exceed qualification levels given in Rosemount Report D8400102.

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.

The process connections to the transmitter flanges were qualified with 3/8-in. tubing using Swagelok® compression fittings. For options using 1/4–18 NPT connections, the user assumes responsibility for qualifying the interface.

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.

Transmitters with Flange Options A, D, H, J, L, or M are shipped with Swagelok fittings for process connections. Included are front ferrule, rear ferrule, and nut. Ensure that the fittings are placed on the tubing with the orientation and relative position shown in Detail A, Figure 2-5 on page 2-7. Process tubing used is 3/8-inch outside diameter, and of suitable thickness for the pressure involved.

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 the nut slightly with a wrench. For more information regarding the use of Swagelok tube fittings, refer to:

Fittings Catalog MS-01-140

“Gaugable Tube Fittings and Adapter Fittings” www.swagelok.com

If the drain/vent valves must be opened to bleed process lines, torque them to 7.5 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 2-8).

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 2-8).

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 2-8).

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.

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.

 

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 1/2–14 NPT. 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

This section contains information that you should consider when preparing to

CONSIDERATIONS

make electrical connections to the transmitter. Read this section carefully

 

before proceeding to the electrical installation procedures.

 

The Rosemount 1154 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

 

at least 12 volts to the transmitter terminals at 30 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 2-3 on page 2-5. See qualification

 

report D8400102 for details. The load is the sum of the resistance of the

 

signal leads and the load resistance of the receivers.

Connections.

Figure 2-3. Supply Voltage vs. Load.

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 transmitter case ground through the sensing element. Because of this coupling, a voltage may be imposed across the load, depending on choice of grounding.

The 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 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.
