PCT No. PCT/DE90/00399 Sec. 371 Date Dec. 18, 1990 Sec. 102(e) Date Dec. 18, 1990 PCT Filed May 30, 1990 PCT Pub. No. WO90/15335 PCT Pub. Date Dec. 13, 1990.In a sensor (10) for determining the angular velocity ((Omega)), an ultrasonic wave is radiated into a sound conductor (11) by means of a piezoceramic shear oscillator (12) as transmitter, two receivers (14, 15) being located adjacent to one another at the other end of the sound conductor (11) so as to be separated from one another by a narrow gap (16). If no angular velocity ((Omega)) acts on the sensor (10), the ultrasonic wave directed to the gap (16) should excite the two receivers equally, so that the differential signal of the two receivers (14, 15)-supported by an alignment-is equal to zero. If the sensor (10) is located in a rotating system, the ultrasonic ray is deflected by means of the acting Coriolis force (+E,rar/K/ c), so that a differential signal of the two receivers (14, 15) is obtained, which differential signal is a measurement for the angular velocity ((Omega)). The sensor (10) has a simple, mechanically stable construction with low sensitivity to shaking and temperature.
