INTRODUCTION
Process pressure devices provide critical process measurement information to process
plant’s control systems. The performance of process pressure instruments are often critical
to optimizing operation of the plant or proper functioning of the plant’s safety systems.
Process pressure instruments are often installed in harsh operating environments
Pressure Applications
causing their performance to shift or change over time. To keep these devices operating
within expected limits requires periodic verification, maintenance and calibration.
There is no one size fits all pressure test tool that meets the requirements of all users
performing pressure instrument maintenance.

DOCUMENTING PROCESS CALIBRATOR

Pressure transmitter manufacturers have improved the accuracy
and technology designed into these smart pressure measurement
devices. Many conventional calibration tools have become inadequate or simply unable to test and calibrate these high accuracy
pressure transmitters. Better test solutions are required.
Verifying and documenting the performance and adjusting
a HART smart pressure transmitter can require a bucket full of
tools. Performing this task with a HART enabled calibrator like
the Fluke 754 simplifies the task and reduces what you need
to carry.
Before going to the field: install the pressure module adapter
to the hand pump with thread seal. Once the adapter is properly
installed on the pump, changing modules to different pressure
ranges is a snap, no tools required.
To get the accuracy needed: to test these new high accuracy
transmitters match the pressure measurement standard range
closely to the device tested. For example, use a 100 psi
pressure module to calibrate and test a transmitter ranged at
100 psi. Industry standards suggest the measurement standard
should be 4-10 times more accurate than the device being tested
so best-in-class accuracy is required.
The Fluke 754 utilizes the 750P series pressure modules and
has built-in HART functionality to enable smart trims on transmitters. It can also document transmitter performance before and
after adjustment and calculate pass/fail errors.

TECH
TIPS
Sometimes it is necessary to trim
the input sensor of the transmitter more than once. It is critical
that the pressure module be zeroed before test and adjustment.
For best ßadjustment success:
• After pressing Fetch for
the pressure measurement,
select the trim button quickly
before the pressure measurement changes.
• Give the measured mA and
pressure time to settle for best
measurement results.
• Always de-bug the pressure
test setup for leaks in the
shop before going to the
field, including installing the
pressure module connection
adapter to the hand pump.
• If the full scale value of the
transmitter is less than 25 %
of the full scale of the pressure module, select a lower
range pressure module for
best results.
• If performing higher
pressure calibrations with a
hydraulic pump, use the correct fluid such as mineral oil
or de-ionized water. Standard
tap water will leave deposits
in the pump and cause
erratic operation, leaks or
difficulty priming.
• If the pass/fail accuracy is set
at the limits for the transmitter, adjust the transmitter if
the errors are greater than
25 % of limits.
• If the errors are less than
25 % of limits, it might be best
to not adjust the transmitter
as adjusting might make it
less accurate.

Accurate calibration of pressure
switches is a critical step in
ensuring process quality and
the safe operation of equipment.
The setup is similar to pressure
gauge calibration except
now a voltage or continuity
across a set of switch contacts
needs to be read either by a
(Digital Multimeter) DMM or
the calibrator. The purpose of
the calibration is to detect and
correct errors in the set point
and deadband of the pressure
switch. Calibrators can save
you time by reducing steps
and reducing the amount of
equipment you have to bring
to the job. With the right
calibrator the entire process
can be automated.

To perform the test:
When you use a Fluke 754
or 3130 to automate the
pressure switch calibration,
vary the applied pressure
slowly, back and forth across
the setpoint and reset points.
The display will make it
apparent that the set/reset
has changed and the actuals
will be logged.
Setup
STEP Safely disconnect the device from the process it controls.

To perform the test:
With a modern documenting calibrator you can test for dry contacts opening and
closing on the switch or if you are using the Fluke 753 or 754 you can leave the
switch connected to the live voltage and the calibrator will measure the changing
AC voltage and interpret it as opening and closing of the switch.
One cautionary note: it is always safer to test a de-energized circuit, but this is not
always possible. Also, do not measure AC voltages above 300 V ac as that is the
maximum rating of the 75X family. 480 V ac 3-phase voltages must be de-energized
and disconnected from the switch if testing with the 75X family.
Classic methods for pressure switch testing have
been superseded with the introduction of new
pressure test tools. Today most pressure switches
are tested with a pressure gauge mounted to
a pump to supply and measure pressure, and
a DMM set to continuity to verify the opening
and closing of the switch. The technician
or electrician making the test is required to
interpret the pressure applied to the switch
when the continuity beeper sounds indicating
contact closure of the switch. A workable
solution but new tools can make this task easier.
Modern calibrators can automatically record
the pressure applied when a pressure switch
changes from open to closed and from closed to
open. In doing so the switch set point and reset
point and deadband are much easier
to determine.
STEP To get started testing the switch, connect as shown above. In this example
1
we will test dry contacts and continuity. To measure continuity for the test
select resistance measurement. Then toggle to the source screen mode
and select pressure to display the pressure generated by the hand pump
and measured by the pressure module. Advance the calibrator mode to the
split screen test mode.
STEP The next step is to describe the switch and whether it is normally open

Suggested test tools
or closed at ambient pressure. The relaxed state of the switch is the
reset state. The set state is the condition of the switch it changes to with
applied pressure or vacuum. In this example the switch is normally open
and is expected to close when the pressure applied exceeds 10 psi. Next
the allowable pressure variance of the switch set state and deadband size
needs to be defined. In this example the ideal switch set value is
10 psi and is allowed +/- 1 psi of deviation. The allowable reset pressure
is described in the deadband tolerance. In this instance the reset state
must be more than 1 psi less than the found set pressure but not greater
than 3 psi less than the found set pressure.
STEP Once the test tolerances are fully defined start the test. Increase the

pressure until the calibrator captures the set state pressure value. Then
decrease the pressure until the reset pressure is found. Repeat increasing
and decreasing the pressure across the switch looking for repeatability in
your set and reset pressure measurements. Once satisfied with the result
press done to get the pass/fail evaluation of the switch. If the switch fails
the test adjustment or replacement of the switch may be required. If the
switch is adjusted repeat the test to document the As-Left condition of the
switch before putting back into service. The test result is now documented
and ready for upload to calibration management software.
• The key to a good switch
test is repeatability.
Repeatability is best
achieved by applying a
slow change in pressure to
the switch as it approaches
its set or reset pressure.
• When performing the test
find out where the switch
sets and make sure the
vernier/fine adjustment of
your test pump has enough
adjustment to vary the
pressure up to the set point.
In this way the pressure
can be changed slowly
capturing an accurate
switch set point pressure.
Repeat this procedure for
the reset point.
• With practice you can get
the vernier of the pump
within range of the set and
reset point pressure and
get excellent repeatability
of your tests (within the
limitations of the switch
being tested).

Gas custody transfer flow computers that calculate
flow in pipelines by measuring the differential
pressure across a flow restriction, such as an
orifice plate or other differential pressure flow
device, require special calibration to perform at
optimum accuracy. Gas flow computers make
three primary measurements to calculate flow:
volumetric flow (difference in pressure across the
orifice plate), static pressure in a pipeline and gas
temperature. A calculation is performed using this
data to determine the actual mass and volume of
the gas flowing through the pipeline.
These calibrations can be made with three
separate calibrators, a low pressure, high pressure
and a temperature calibrator or use a multifunction
calibration tool designed for this specific task.
An example of a calibrator purposed for this
task is the Fluke 721 or 721Ex. It has two builtin pressure ranges and the ability to measure
temperature. The most popular configuration is
16 psi/1 bar on the low pressure (P1) sensor side
and 1500/100 bar or 3000 psi/200 bar on the high
pressure (P2) sensor side. It measures temperature
using a precision RTD accessory and can display all
three measurements at once if desired.

To perform the test:
To get started, isolate the flow computer from the pipeline. It is normally installed with a 5 valve manifold. If so, closing the valves on the pipeline side
of the manifold should isolate it. Be sure to follow local policy and safety
procedures when performing this isolation step. Set the P1 sensor of the
721 to measure inH20 and the P2 sensor to measure PSI and the temperature sensor to measure degrees Celsius or Fahrenheit as needed.
STEP Low pressure differential pressure calibration is performed using
1
atmospheric pressure as a low side reference. Vent the low connection
of the flow computer or pressure transmitter and connect the high pressure
connection of the flow computer or transmitter to the low pressure port (P1)
on the calibrator.
Connect the computer (PC) to the flow computer serial or USB port. The PC
will instruct the user to apply one or more test pressures to the flow computer or transmitter. For example, 0, 100 and 200 inH20. Squeeze the pump
to get close to the test pressure and use the vernier or fine pressure adjust
to dial in.
STEP Static pressure calibration will normally be applied to either the same
2

high pressure port of the flow computer or both the high and low pressure
ports. Refer to the manufacturer’s instructions for details. Connect the high
pressure sensor input (P2) to the appropriate port on the flow computer or
transmitter and to the high pressure test source. The PC will instruct the
pressures for the user to apply from the pressure source.
TECH
TIPS
• Always center the vernier
of your hand pump before
starting any pressure
calibration. This will allow
you to increase or decrease
the pressure when making
fine adjustments.
• Store the temperature
probe in a protective
case such as the built in
slot of the 721 soft case.
Exposing the RTD probe
to mechanical stress can
reduce the measurement
accuracy of the probe.
• Be careful to not connect
the P1 low pressure
side of the calibrator
when doing high
pressure calibrations
or measurement or the
sensor will be damaged
and possibly rupture
creating a dangerous
condition.
• Inserting the RTD probe
prior to the pressure
calibrations typically
allows sufficient time to
reach a stable temperature
measurement.
STEP Temperature calibration of the temperature measurement on the flow
3
computer is done with a single temperature point at the pipeline operating
temperature. Insert the RTD probe into the test thermowell and allow time
for the measurement to stabilize.
The PC will prompt the user to enter the temperature measured by the
calibrator. Remove the RTD from the test thermowell and the calibration is
complete.

parameters into 4 to 20 mA signals. In this instance these transmitters may
need individual calibration if the test results are not satisfactory (see HART

computer. These can be independently tested using a mA signal source
from a loop calibrator.

Verifying process gauges,
analog and digital
Both analog and digital process
gauges need to be verified to
detect errors related to drift,
environment, electrical supply,
addition of components to the
output loop, and other process
changes. Pressure gauges may
be verified in the field or at
the bench. Field calibration
may save time, and allows for
troubleshooting in the process
environment. Multifunction
calibrators make it easier to
do this with one tool, and
documenting calibrators make
it easier to follow procedures,
capture data and document
results. Bench calibration
provides an environment
where the gauge can be
cleaned, inspected, tested, and
recertified under reference
conditions for the best
possible accuracy.

they will eventually leak. Each time - a push
fit hose is connected, it leaves a mark on the
test hose and eventually does not seal well.
To eliminate the leak cut off the affected

Application Note
• When using hydraulic hand pumps
remember the thermodynamic effect. Once
any fluid is compressed, the temperature
increases and the fluid expands. This
becomes obvious when pumping to a target
pressure with a hydraulic pump. Once
the target pressure is met the fluid has
expanded. As the fluid cools and contracts
the pressure quickly bleeds down until
it reaches temperature equilibrium, this
can take 5 minutes or more. Once the
temperature stops changing, dial the desired
pressure back in with the vernier adjuster.

INTRODUCTION
Temperature devices in process manufacturing environments provide measurements to
the process plants’ control systems. The performance of these temperature instruments
is often critical to optimized operation of the process manufacturing plant or proper
functioning of the plant’s safety systems.
Temperature Applications
Process temperature instruments are often installed in harsh operating environments,
causing their performance and the performance of their sensors to shift or change over
time. Keeping these devices measuring temperature within expected limits requires
periodic verification, maintenance and adjustments.

They should be tested during commissioning
and again when removed from a process to
verify that tolerances were met. Additionally,
thermocouples may be tested at regular
calibration intervals and when suspected of
failing to meet their performance specifications.
Often thermocouples need to be calibrated prior
to use for mapping a temperature controlled
enclosure, or they have to be calibrated for use
as a temperature standard.
Due to the unique characteristics of
thermocouples, they are best calibrated in
situ (in place) by comparison to a temperature
standard. However, in situations where that
is not practical, it is necessary to remove
the thermocouple and place it in a precision
temperature source such as a dry-well.

• Thermocouple wire
generates a voltage
whenever two adjacent
points along the wire are at
different temperatures.
• The whole length of the
wire (not just the probe

Using a precision thermometer for single
point process temperature verification
RS 232
It’s not always possible or practical to remove
instruments from a process for calibration. In situ
verification at a single point may be the only way
to know whether an instrument is performing
as expected. A single point verification is
most effective over a narrow temperature
range and when combined with other trends
and information related to the process and
equipment. It also requires the process not to be
in a dynamic state of change.

a temperature standard such a reference PRT
connected to a readout such as a 1523A is
placed in thermal equilibrium with the sensor of
the instrument to be verified without removing
it from the process. Usually this is accomplished
with a test well that is installed in a location
adjacent to the sensor to be tested.

Temperature switch and

Temperature switches and controllers are
commonly used in small processes and in control
loops where a programmable logic controller
(PLC) or larger distributed control system (DCS)
are not warranted.
Temperature controllers provide both switching
capability based on rising and dropping
temperatures, as well as a local indication of the
measured temperature.
Most temperature controllers have some form of
tuning, using damping and PID (Proportional,
Integral and Derivative values) for smoothing out
the measured process temperature,
reducing variability.

The terminology around switches can be
confusing. The set state of the switch is the
action the switch takes when an input stimulus
above or below a specified value is applied. This
stimulus can prompt an action such as closing
a switch, which in turn starts or stops a motor,
or opens and closes a valve. The reset point
is considered the relaxed state of the switch,
which is typically referred to as “Normally Open”
or “Normally Closed.” This describes the default
condition of the switch. Lastly, deadband is the
band of temperature equal to the difference
between the temperatures where a switch sets,
and resets. See illustration at left.

Temperature switch and
controller testing at the bench
A temperature switch is a device that protects
a thermal system by sensing temperature and
closing or opening a switch to shut down a
process or equipment if the temperature is
outside the safe range.
Temperature
Switch sets - closed
Temperature switches are often calibrated or
tested for safety reasons to determine how
accurate and repeatable the device is. The
temperature at which a switch activates is called
the set point and is an important value that needs
to be verified during testing.
Another critical safety related value is called the
deadband. Below the low end of the deadband,
the heating system turns on. Above the high end
of the deadband, the heating system turns off.
Switch tests may be operated manually or
automatically. If the electronics are not built
into the dry-well for a switch test, then a
DMM will be needed to determine the open/
close condition. Metrology Wells and most
Field Metrology Wells have built-in routines to
automate switch testing.

TIPS
In industrial process industries, temperature
measurement equipment usually has two
components: a sensing device such as an RTD or
thermocouple and a transmitter to read and relay
the signal to the control system.
All sensors, including RTDs, drift with time.
Thus, testing the transmitter and not the sensor
could result in misjudgment regarding a system’s
performance. To avoid this potential problem,
process instrument manufacturers recommend
including the temperature sensor in loop
calibration to prove the effectiveness of the
entire system.
