VERIFICATION OF PROCESS VARIABLE TRANSMITTER

摘要

A method and apparatus for verifying operation of process variable transmitters in process control or monitoring systems (100) is provided. A process variable is measured with a process variable transmitter (102) to verify operation of the process variable transmitter (108) by comparing the process variable with a reference. A data entry is placed in a database (130) which indicates operation of the process variable transmitter (102) has been verified.
