Abstract

L'invention concerne les dispositifs indicateurs de position. Elle a pour objet un dispositif comprenant un disque rotatif 10 muni références 11, 11', ainsi qu'un capteur fixe 12 et un capteur mobile 13 lié à l'organe mobile dont on désire détecter la position, ces capteurs émettant à chaque tour une impulsion au passage des références 11, 11'. Les impulsions émises activent et désactivent convenablement des compteurs 21, 23 recevant une fréquence fixe d'un générateur 18, et un calculateur fournit un signal numérique de position de l'organe mobile à partir des nombres d'impulsions totalisés par lesdits compteurs. Application au relèvement des positions du papillon des gaz d'un moteur à explosion.The invention relates to position indicating devices. It relates to a device comprising a rotating disc 10 provided with references 11, 11 ', as well as a fixed sensor 12 and a mobile sensor 13 linked to the mobile member whose position it is desired to detect, these sensors emitting at each turn a pulse when passing references 11, 11 '. The pulses emitted suitably activate and deactivate counters 21, 23 receiving a fixed frequency from a generator 18, and a computer supplies a digital signal of the position of the moving member from the numbers of pulses totaled by said counters. Application to the detection of the positions of the throttle valve of an internal combustion engine.
