Abstract: To provide a rotation sensor for detecting a relative rotation angle, which shows little variation in detection accuracy even in the presence of disturbances. The rotation sensor detects a variation in impedance of each of two exciting coils (12b) which is produced depending on the strength of eddy currents induced in first and second rotors (11, 13), and determines a relative rotation angle on the basis of a difference between the amounts of both variations. A first conductive layer (11a) is provided on at least one of the opposite sides of the first rotor as viewed along a rotation axis, and consists of a plurality of portions arranged in a circumferential direction of the first rotor with predetermined spaces between. The stationary core (12) is so arranged that a core body (12a) holding the two exciting coils (12b) is symmetrical with respect to a plane normal to the rotation axis.

Abstract: A method and apparatus are described for noncontact measurement of torque applied to a torque-bearing member such as a shaft. The method involves the use of a piezoelectric transducer mechanically coupled to the shaft for rotation therewith, and having electrical characteristics responsive to applied torque. Electrical signal characteristics are changed by the torque-dependent transducer characteristics. The electrical signals are coupled to the outside (non-rotating) world by at least one capacitive coupler. In one embodiment, an fixed-frequency oscillator produces signal, and the transmission of the signal is affected by the torque-dependent resonant frequency of the transducer. In another embodiment, the transducer is coupled in the feedback loop of a circuit to form an oscillator, in which the frequency is responsive to the torque. A transducer may be placed and distributed in a protective holder. The holder may be pierced in particular locations in order to increase or decrease its sensitivity.

Abstract: A capacitive pressure sensor for measuring a pressure applied to an elastic member includes a capacitive plate disposed adjacent to the elastic member so as to define a gap between a planar conductive surface of the elastic member and a corresponding planar surface of the capacitive plate.

The capacitor and the electrical conductor together form an electrical resonator having a characteristic resonant frequency. Varying the capacitance of this tank circuit varies the resonant frequency of the tank circuit.
