IMPORTANT
Rosemount 3152, 3153 and 3154 Series Pressure Transmitters are designed for Nuclear Class 1E usage, and
have been tested to the standards shown below:
• IEEE Std 323™-1974, -1983 and -2003
• IEEE Std 344™-1975, -1987 and -2004
These transmitters are manufactured under a quality system that meets the requirements of 10CFR50
Appendix B, 10CFR Part 21, ISO 9001, NQA-1, KTA 1401, KTA 3507, CSA N285.0, CSA Z299 and the
applicable portions of IAEA-50-C-Q. During qualification testing, interfaces were defined between the
transmitter and its environment that are essential to meeting requirements of the qualification standards listed
above. Specifically, to ensure compliance with 10CFR Part 21, the transmitter must comply with the
requirements herein and in the applicable Rosemount qualification report(s) throughout its installation,
operation and maintenance. It is incumbent upon the user to ensure that the Rosemount Nuclear Instruments,
Inc.’s component traceability program is continued throughout the life of the transmitter.
In order to maintain the qualified status of the transmitter, the essential environmental interfaces must not be
compromised. Performance of any operations on the transmitter other than those specifically authorized in
this manual has the potential for compromising an essential environmental interface. Where the manual
uses the terms requirement, mandatory, must or required, the instructions so referenced must be
carefully followed. Rosemount Nuclear Instruments, Inc. expressly disclaims all responsibility and liability for
transmitters for which the foregoing has not been complied with by the user.

WARNING
NOTE
For steam service, do not blow down impulse piping through the
lines with water before resuming measurement.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
• Install and tighten all four flange bolts before applying
pressure.
• Do not attempt to loosen or remove flange bolts while the
transmitter is in service.
Replacement equipment or spare parts not approved by
Rosemount Nuclear Instruments, Inc. for use could reduce the
pressure retaining capabilities of the transmitter and may render
the instrument dangerous or adversely impact i ts qualified

• Use only components supplied with the Rosemount 3152,
3153 or 3154 transmitter or designated by Rosemount
Nuclear Instruments, Inc. as spare parts for the 3152,
3153 or 3154.
Improper assembly of mounting bracket to traditional process

transmitter close to the process and use a minimum of piping to
achieve best accuracy. For flow measurement, proper installation of
the primary element is also critical to accuracy. Also, consider the
need for easy access, personnel safety, practical field calibration and a
suitable transmitter environment. Transmitter installation should
minimize the effects of temperature gradients and fluctuations, and
avoid vibration and shock during normal operation.

one with a fundamental mechanical resonant frequency of 40 Hz or
greater). Two mounting options are qualified for the transmitter: panel
mount or 2-inch pipe mount. A stainless steel panel bracket is
provided with the 3154. For the 3152 and 3153 series, the user has
the option of specifying either the stamped carbon steel panel bracket
or the stainless steel panel bracket.
Refer to Figure 2-5 for qualified mounting configurations for both the
panel and pipe mount options.
Orientation with respect to gravity is not critical to qualification. For
maximum accuracy, zero the transmitter after installation to cancel any
zero shift that may occur due to liquid head effect caused by mounting
Mounting the transmitter in another position may cause the zero po int to
shift by an amount equivalent to the internal liquid head within the
sensor module induced by the varied mounting position. For maximum
accuracy, zero the transmitter to cancel this effect per Section 3:

Process Connections and
Interfaces
Mount the process flanges with sufficient clearance for process

connections. For safety reasons, place the drain/vent valves so the
process fluid is directed away from possible human contact when the
vents are used. Also consider that access to the vent/drain valve(s)
and process connection(s) may be required for plant specific
operations (i.e. calibration, draining, etc.)
Process tubing must be installed to prevent any added mechanical
stress on the transmitter under seismic conditions. Use stress-relief
loops in the process tubing or separately support the process tubing
close to the transmitter.
Typical connections on the transmitter flanges are ¼ - 18 NPT or 3/8
inch Swagelok ™. Use your plant-approved, qualified thread sealant
when making threaded connections. The end-user is responsible for
the qualification of the threaded seal interface on all ¼ - 18 NPT
interfaces.
Transmitters with options including 3/8 inch Swagelok™ are shipped
with front ferrule, rear ferrule and nut. Place these fittings on the
tubing with the orientation and relative position shown in Figure 2-1.

The piping between the process and the transmitter must accurately
transfer the pressure to obtain accurate measurements. There are fi
possible sources of error: pressure transfer (such as obstruction), leaks,
friction loss (particularly if purging is used), trapped gas in a liquid line
or liquid in a gas line and density variations between the legs.

The 3154 has one conduit connection.
Use a qualified conduit seal at the conduit entry to prevent moisture
from accumulating in the terminal side of the housing during accident
conditions. Certain option codes provide a qualified connector with the
connector factory assembled to the transmitter. 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 in this section.
The standard transmitter orientation is shown in dimensional drawings

carefully before proceeding to the electrical installation procedure.
Rosemount 3150 Series transmitters provide a 4-20 mA signal when
connected to a suitable dc power source. Figure 2-3 illustrates a typical
signal loop consisting of a transmitter, power supply, and various

terminals at 20 mA signal, or the maximum output current required for
proper system operation. Any power supply ripple appears in the
output load. The power supply versus load limitation relationship is
shown in Figure 2-4. See qualification reports for additional details.
The loop load is the sum of the resistance of the signal leads and the
load resistance of the receivers.

circuit with a nominal frequency of 110 kHz +/- 11 kHz. This 110 kHz
signal is capacitively-coupled to the transmitter case ground th
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

point are negligibly affected by this noise and do not need filtering.

1. Attach the mounting bracket to the mounting location as follows:
Panel Mount
Mount the bracket to a panel or other flat surface (for
illustration see Figur e 2-5). Please note that the bolts
required for this step are customer supplied hardware.
Based on qualification tests performed by Rosemount, the
bolts listed in Table 2-1 are recommended for the bracketto-customer interface. Torque each bolt to value shown in

Pipe Mount
Assemble the bracket kit to a 2-inch pipe (for illustration
Figure 2-5). Torque each bolt to value shown in Table 5-2
in Section 5 Maintenance and Troubleshooting.
2. Attach the transmitter to the mounting bracket (for illustration
see Figure 2-5). Use the four 7/16-20 x ¾ inch bolts with
washers supplied with the transmitter. Torque each bolt to
