Control apparatus comprising at least one electrically-conductive target portion (12). A position sensor (14) in the form of a pulse induction device is arranged in proximity with the said at least one electrically-conductive portion (12) to provide a signal indicative of a position attribute of that portion. Relative movement is possible between the target portion (12) and a coil portion (14a of the position sensor (14). Control means (16) are connected to receive such a signal from the pulse induction device (14) and to respond in dependence upon that signal. The invention extends to such a position sensor (14) itself.
L'invention concerne un appareil de commande comportant au moins une portion cible (12) électroconductrice. Un capteur de position (14) se présentant sous la forme d'un dispositif d'induction à impulsions est disposé à proximité de la ou des portions électroconductrices (12) pour délivrer un signal indiquant un attribut de position de cette portion. Un mouvement relatif est possible entre la portion cible (12) et une portion bobine (14<u>a</u>) du capteur de position (14). Des moyens de commande (16) sont reliés pour recevoir un tel signal émanant du dispositif d'induction à impulsions (14) et pour réagir en fonction de ce signal. L'invention concerne également le capteur de position (14) lui-même.
