ABSTRACT:
The torque transducer for rotating machines enables precise measurement of the torque transmitted between a torquing means and a driven load at any rotational speed. A torsionally compliant means is concentrically attached between the torquing means and load shaft attached to the driven load. The torsionally compliant means' angular deformation representing torque is measured between capacitive elements attached to the torquing means and capacitive elements attached to structure attached to the load shaft. An electronic circuit transforms the differential capacitance created by the torsionally compliant means's angular deformation to a voltage proportional to torque.
