Common Configuration and Calibration Tasks for Process Transmitters

Custom Search

Process transmitters especially pressure transmitters are about the most popular piece of electronic device you will ever find in a process plant. Exactly what does it take to get your pressure transmitter up and running?

Listed below are common configuration and calibration tasks recommended to be done on a process transmitters before they become fully operational in the field. These tasks are divided into two basic tasks:

(a) Bench calibration tasks: This calibration task can easily be done on a bench or other suitable location before actual installation in the field or plant

(b)Field calibration tasks: This type of calibration task is done after the transmitter has been installed in the field or plant

Bench Calibration Tasks
The common bench calibration tasks recommended for a pressure transmitter before installation are:
(1) Setup of output configuration tasks:
     (a) Set the range points
     (b) Set the output points
     (c) Set the output type
     (d) Set damping value
(2) Perform a sensor trim if required - see how to perform a sensor trim

Basics of Smart Pressure Transmitter Calibration

Field Calibration Tasks
(1) Reconfigure parameters if necessary
(2) Zero trim the transmitter to compensate for mounting effects or static pressure 
     effects.
(3) Perform an analog output trim if required – see how to perform an analog
     output trim.
