Wireless transmission from moving parts

摘要

The arrangement has a measurement transducer (M) and a measurement system containing an antenna (A2,A3) near the transducer, and at least one electronic assembly. At least one supply frequency is generated in the measurement system, which is radiated to the measurement transducer and received from the transducer. The transducer has at least one resonator coupled to at least one non-linear electronic component. The resonator is influenced by the value being measured. For mixing, or forming harmonics multiples of the supply frequency, the sums or differences of several supply frequencies are formed in the non-linear component. The frequencies formed in the transducer stimulate the resonator which transmits the measurement information to the receiver, at a measurement frequency lower then the supply frequencies.
