Calibrating a HART

Smart Pressure Transmitter

Pressure transmitter manufacturers have improved the accuracy
and technology designed into these smart pressure measurement

devices. Many conventional calibration tools have become inad-
equate 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 simpliies the task and reduces what you need

to carry.

Before going to the ield: 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 trans-

mitters. It can also document transmitter performance before and
after adjustment and calculate pass/fail errors.
