Abstract

A registering system in the form of a communication system with means on the transmitter side for the transmission of a phase-modulated high frequency signal. A receiver in a sensor includes an electronic relay (5) supplying the remaining circuits in the sensor with energy at the receiving of a signal. The remaining circuits phase- detect (at 7) the received signal to produce a pulse for each period, the number of pulses being counted and compared with a predetermined value in the sensor and a signal being transmitted in case of identity. The frequency of the signal transmitted is preferably the second harmonic series of the signal received, a loop on the transmitter side being arranged to produce the same harmonic series of the modulated transmitted signal. The signal received and the harmonic series are transferred to a multiplier (12), the moment of a possible signal transmission from the multiplier corresponding to the predetermined value in the sensor. <IMAGE>
