ABSTRACT:
Disclosed is apparatus and a system for measuring and monitoring the actual mechanical power being produced by an electric motor and measuring and monitoring the reactive torque acting on and the rotational speed of a drive shaft of the electric motor used to drive a valve actuator of a motor operated valve (MOV). The apparatus and system is comprised of a motor power measuring cell inserted between and bolted to the electric motor housing and to the valve actuator housing of commercial MOVs to provide continuous in-service valve and motor diagnostics. The motor power measuring cell is provided with a first measuring means for measuring the torque acting on the drive shaft and a second measuring means for measuring the rotational speed of the drive shaft.
