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.
