FIELD: measurement technology. SUBSTANCE: invention deals with passive transducer based on surface acoustic waves used to determining measurement values and to transmit measured values from remote place over radio into interrogator 1 that sends energy to sensitive element 5, 15 in the capacity of interrogation pulse over radio. Transducer based on surface acoustic waves is used for contactless recording of measurement values. Surface acoustic wave device is sensitive element. There is provided reference element based on surface acoustic waves employed for discrimination and/or measurement of time of passage. Transducer can be used to measure physical and other values. EFFECT: higher efficiency. 37 cl, 16 dwg
