ABSTRACT:
A method and apparatus for measuring and monitoring the axial load or thrust on the valve stem of an air operated valve assembly. The top end of the valve stem is connected to bottom end of the valve actuator drive shaft by a marriage block connector member having a plurality of strain gages capable of generating an electrical signal representative of the axial load or thrust on the valve stem. The marriage block connector member is also provided with a gage capable of generating an electrical signal representative of the axial position of the valve stem. The apparatus and methods disclosed are used for valve diagnostic testing from a remote location or for a valve control system.
