This part of IEC 62828 establishes specific procedures for testing pressure process measurement transmitters (PMT) used in measuring and control systems for industrial processes and for machinery control systems.
A pressure PMT can feature a remote seal to bring the process variable to the sensing element in the PMT. When the remote seal cannot be separated from the PMT, the complete device is tested.
For general test procedures, reference is made to IEC 62828-1, which is applicable to all types of process measurement transmitters.
NOTE In industrial and process applications, to indicate the process measurement transmitters, it is common also to use the terms \'industrial transmitters\', or \'process transmitters\'.
