MONITORING COUPLING STATUS WITH PROCESS LOCKOUT FEEDBACK

摘要

A monitoring system includes a porthole in a tank or conduit that includes threads on an end thereof. A piece of processing equipment is mounted within the porthole by a threaded coupling collar. The treads of the coupling collar engage the threads of the porthole. A sensor collar is mounted in fixed relationship to the porthole at a predetermined distance from an end of the porthole and includes a status sensor mounted thereto. The status sensor detects a position of the threaded coupling collar to ensure that the piece of processing equipment is properly mounted in the porthole.
