Abstract
A torque/position transducer is positioned between the valve stem of a valve and a valve operator and includes a body section including an input lug mated with the output lug of the valve operator and an output lug mated with the valve stem of the valve. Strain gauges mounted on the body generate an output signal indicate of the amount of torque necessary to open or close the valve. A magneto-resistive sensor generates a signal indicative of the position of the valve stem with respect to the valve. In another embodiment, the strain gauges are mounted on the valve stem.
