Abstract
A motor operated valve monitoring system utilizes two diagnostic couplings with quick disconnect electrical connectors. One coupling is used for monitoring switch actuation on the motor operated valve, and the second is for measuring three phase power to an AC motor on the valve. These couplings are connected in-line with the quick disconnect connectors and allows the user to perform a test without having to remove the limit switch cover from the actuator. These couplings will reduce testing time for conventional valve monitoring systems, and provide for readily mountable sensors for installation of an online valve diagnostic system to an existing valve and valve operator.
