Industry Information
Failure analysis steps of pressure control instrument system
2011-6-30 17:14:47

(1) When a rapid oscillation fluctuation is indicated by the pressure control system instrument , first check whether there is a change in the process operation. Most of this change is caused by the poor operation of the process operation and regulator PID parameters.

(2) The dead line of the pressure control system indicator indicates that the pressure indication remains unchanged when the process operation changes. Generally, the fault occurs in the pressure measurement system. First, check whether the measurement impulse conduit system is blocked, and check whether the pressure changes. Whether the output system of the transmitter is changed or not, the fault lies in the controller's measurement and indication system.
