CAPACITIVE SENSOR FOR TORQUE MEASUREMENT

Abstract:
Based on acapacitive angle/angular speed sensor a sensor measuring the torque on a rotating shaft has been developed. The torsion resulting from the torque on the shaft is measured by two rotatable electro desplaced between two sensor plates. The relative angle between the two rotors is calculated from measurements of the capacitive coupling between different transmitting stator segments. A prototype of this sensor has been developed with a range of the torque of ± 2 N·m with a measurement error of 0.04 N·m and a resolution of 0.02 N·m.
