HIM HART loop monitor combines with Fisher Fieldvue DVC6000 valve controller to facilitate partial valve stroke testing.
HIM HART loop monitor combines with Fisher Fieldvue DVC6000 valve controller to facilitate partial valve stroke testing. Monitor has ability to confirm that the valve controller is performing a partial valve stroke test to validate proper emergency shutdown (ESD) valve operation. If the test has failed, an alarm alerts the user that the ESD valve is stuck. Valve controller sends digital information on the HART loop. HIM continuously monitors the HART data from the valve controller. When a valve stroke test is initiated, the HIM sends an alarm trip (relay) output to confirm that a test is in program. A stuck valve causes the HIM to initiate a second alarm to alert operators to the condition.
