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.

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.

connections oriented on the bottom for gas service and on the top for

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.

Review this section to become familiar with the fundamentals of
calibrating the Rosemount 3150 Series transmitter. Contact
Rosemount Nuclear Instruments, Inc. with questions regarding
calibrations that are not explained in this manual.

Rosemount 3150 Series transmitters are factory calibrated to the range
shown on the nameplate (see Figure 1-1). This range may be changed
within the limits of the transmitter. Zero may also be adjusted to elevate
(for all models except absolute pressure reference) or suppress (for all
models). Calibrations that hav e a lower rang e va lue b elow zero are
termed zero elevated while calibrations that have a lower range value
above zero are termed zero suppressed.

The zero and span are adjusted during calibration using zero and span
adjustment screws. The adjustment screws are accessible externally
and are located behind the access cover plate on the side of the
electronics housing (see Figure 3-1). Transmitter output increases with
clockwise rotation of the adjustment screws. For normal calibration
adjustments, the zero adjustment screw has negligible effect on the
span and the span adjustment has negligible effect on the zero.

For large amounts of zero adjustment, a course zero selection jumper is
provided. The jumper is located on the electronics assembly,
accessible within the electronics hous in g as shown in F igures 3-1 and
3-2. Models ordered with optional output damping will have a damping
adjustment potentiometer located on the amplifier board (see Figure 3-

2).
Procedures for calibration, including setting the course zero selection

jumper and optional damping adjustment, are provided later in this

calibration:
DP

Differential pressure between the high pressure “H” and low pressure
“L” process inputs, as marked on the transmitter module.

Upper Range Limit (URL)

The highest pressure the transmitter can be adjusted to measure,
specified in the model ordering information by pressure range code.

Upper Range Value (URV)

The highest pressure the transmitter is adjusted to measure. This
pressure corresponds to 20mA output point.

Lower Range Value (LRV)
The lowest pressure the transmitter is adjusted to measure. This
pressure corresponds to the 4mA output point.

Span = |URV - LRV|
Zero Based Calibration

Calibration where the LRV is zero DP (see Figure 3-3)

Elevated Zero Calibration

Calibration where the LRV is less than zero DP (i.e. the LRV is
achieved when a positive pressure is applied to the low
the DP cell or a vacuum is applied to the high pressure side of the DP
cell – see Figure 3-3).

Suppressed Zero Calibration

Calibration where the LRV is greater than zero DP (i.e. the LRV is
achieved when a positive pressure is applied to the high pressure side
of the DP cell or a vacuum is applied to the low pressure side of the DP
cell – see Figure 3-3).

% Zero Offset

= (LRV/URL) X 100
Note: % Zero Offset is used when making coarse zero adjustments and
replaces the traditional % Zero Elevation and % Zero Suppression
terms. This concept is used due to the limited interaction between zero
and span adjustments on the 3150 series pressure transmitter.

Sign Convention

Positive numbers indicate positive pressure is applied to the high
pressure side of the DP cell or a vacuum is applied to the low pressure
side of the DP cell. The high pressure side is indicated on the sensor
module by an “H”.

Negative numbers indicate positive pressure is applied to the low
pressure side of the DP cell or a vacuum is applied to the high pressure
side of the DP cell. The low pressure side is indicated on the sensor

the procedure below:

1. Calculate the % zero offset using the following formula:
% Zero Offset = (LRV/URV) X 100

Where:
LRV = Lower Range Value of desired calibration
URL = Transmitter Upper Range Limit

2. Consult Table 3-1 to determine recommended jumper

B (3152) and T (3153 and 3154) are designed to permit damping of
rapid pulsations in the pressure source through adjustment of the
single turn damping adjustment potentiometer (see Figure 3-2).
When adjusted to the maximum position (clockwise stop), time­constant values of at least 1.20 seconds are available for 3152, 3153,
and 3154 transmitters. Transmitters with the electronics damping
option are calibrated and shipped with the adjustment set at the
counterclockwise stop, giving the minimum time constant.

Damping adjustment should be made with the transmitter calibrated
to the intended application calibration. 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, damping may be adjusted 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

The correction factor for span shift caused by the application of static
line pressure is shown in Table 3-2

(1) Correction factors have an uncertainty of ±0.20% of

input reading per 1000 psi (6,90 MPa)

The following illustrates two methods of correcting for the high static
pressure span shift. Examples follow each method.

Method 1 for High Static Line Pressure, Ranges 4 and 5

Adjust transmitter output while leaving the input pressure at desired in
service differential pressures. Use on of the following formula sets
(depending on the pressure units being used to calibrate):

If using English Units (psi):

Corrected output reading (at LRV) =

4 mA + ((S X P/1000 X LRV)/Span) X 16 mA

Corrected output reading (at URV) =

20 mA + ((S X P/1000 X URV)/Span) X 16 mA

If using SI Units (MPa):

Corrected output reading (at LRV) =

4 mA + ((S X P/6,90 X LRV)/Span) X 16 mA

Corrected output reading (at URV) =

20 mA + ((S X P/6,90 X URV)/Span) X 16 mA

Where:

S = Value from Table 3-2 divided by 100
LRV = Lower Range Value
URV = Upper Range Value
P = Static Line Pressure

regulated voltage of 7.4 Vdc for the oscillator and amplifiers

The current control amplifier consists of two operational amplifiers, two

adjustable gain output proportional to the sum of the differential sensor
current and a zero adjustment current. This output is supplied to the
second amplifier, which controls the current in the 4-20mA loop
proportionally.

The current limiter prevents output current from exceeding 30mA

limited to 3 mA nominal. Both the minimum and maximum current limits
may vary slightly depending upon sensor pressure range code and
associated calibration.
