ABSTRACT:
In order to measure torques on valves, measuring devices have heretofore been used which measure the force to be transmitted with the aid of weighing cells fitted with strain gauges. The structural make-up of such devices and the structural size resulting therefrom are not suitable to permit the measuring device to be permanently left between the valve and the electromotor, so that these measuring devices can be used only for periodic measurements. It is accordingly an object of the invention to provide a permanently installed device which allows continuous torque measurement. For this purpose, the housing of the actuator and the housing of the valve are connected to one another through a flanged bush. The flanged bush carries a strain gauge in the region of a recess, and has a clearance for the passage of the valve stem. While the flux of force reaches through an adaptor from the actuator to a threaded sleeve which adjusts the valve stem, the flanged bush fixedly disposed between the actuator and the valve is subjected to a torsional moment which is measured with the strain gauge.
