Abstract: A thrust-torque transducer for measuring the end thrust or torque of a rotating shaft comprising a thrust bearing producing an axial displacement of the shaft from a no load or null position and an LVDT (Linear Voltage Differential Transformer) having a movable core axially aligned with, secured to and rotatable with the shaft producing an output signal corresponding to thrust or torque. A feedback loop may be incorporated in the transducer to maintain the shaft in the no load or null position from which a signal may be obtained corresponding to thrust or torque.
