Analyze the description of the steps of the pressure control instrument system

(1) When the pressure control system indicates that there is rapid oscillation fluctuation, first check whether the process operation has changed. This change is mostly caused by poor process setting and PID parameter setting of the regulator.

(2) The pressure control system indicates that the dead line is present, the process operation changes the pressure indication or does not change, the general fault appears in the pressure measurement system, first check whether the measurement of the pressure guiding conduit system is blocked, not blocked, check the pressure change The transmitter output system has no change, there is a change, and the fault is in the controller measurement indication system.
