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.<\/p>\n

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.<\/p>\n

For general test procedures, reference is made to IEC 62828-1, which is applicable to all types of process measurement transmitters.<\/p>\n

\n

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”.<\/p>\n<\/blockquote>\n
