ABSTRACT:
A sensor system for remote detection of a measurable variable includes a sensor, with a first resonator (5) which has a resonant frequency that is variable under the influence of the measurable variable; an antenna (1) for sending and receiving a modulated high-frequency signal; a modem (2) for coupling the first resonator (5) to the antenna; and a second resonator (3) that can be excited by a carrier frequency of the high-frequency signal. An interrogation unit generates an inquiry radio signal for exciting the two resonators and interrupts the broadcasting of the inquiry radio signal in order to receive a response radio signal broadcast by the sensor.
