Abstract
A sensor system for remote detection of a measurable variable includes a sensor, with a first resonator () which has a resonant frequency that is variable under the influence of the measurable variable; an antenna () for sending and receiving a modulated high-frequency signal; a modem () for coupling the first resonator () to the antenna; and a second resonator () 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.
