Abstract

Détecteur de proximité capacitif. Un récepteur est associé à l'émetteur à haute fréquence entre l'émetteur à haute fréquence et le récepteur est branché un condensateur à champ de dispersion, qui sert à l'émission et à la réception d'un signal issu de l'émetteur ainsi qu'à la détection d'une variation du signal de l'émetteur provoquée par l'approche d'un corps, l'une des armatures du condensateur à champ de dispersion étant reliée à la sortie de l'émetteur, tandis que l'autre armature est reliée à l'entrée de l'émetteur. Entre l'emetteur à haute fréquence et le récepteur, il est prévu un montage de compensation, et qu'une partie de la tension de l'émetteur est appliquée au récepteur par l'intermédiaire du montage de compensation Systèmes de surveillance électronique.Capacitive proximity switch. A receiver is associated with the high frequency transmitter between the high frequency transmitter and the receiver is connected a stray field capacitor, which is used to transmit and receive a signal from the transmitter as well upon detection of a change in the transmitter signal caused by approaching a body, one of the armatures of the stray field capacitor being connected to the output of the transmitter, while the other armature is connected to the input of the transmitter. Between the high frequency transmitter and the receiver, there is a compensating circuit, and part of the voltage from the transmitter is applied to the receiver through the compensating circuit Electronic Monitoring Systems.
