1 Scope

This document specifies process pressure measurement transmitters (PMT, as hereinafter referred to as pressure transmitter or transmitter) specific test procedures:

The pressure transmitter can use the remote seal to lead the process variable to the sensing element of the pressure transmitter: When not available from the pressure transmitter

When the remote seal is separated, the entire pressure transmitter needs to be tested:

For general test procedures, please refer to GB/T 42567:1-2023, which applies to all types of industrial process measurement transmitters:

NOTE: In industrial process applications, the term "industrial transmitter" or "process transmitter" is often also used to indicate a process measurement transmitter:
