Abstract

L'invention concerne les dispositifs de lecture à distance des compteurs. Elle se rapporte à un appareil dans lequel une aiguille rotative 12 d'un compteur Il passe devant un transducteur 10 ayant des électrodes 14 formant un cercle dont le centre est aligné sur l'axe de rotation de l'aiguille 12. Les électrodes forment des paires diamétralement opposées qui reçoivent une phase d'une tension polyphasée, avec des polarités opposées. Une électrode centrale détecte la position, la vitesse ou le sens de déplacement de l'aiguille 12. Application à la lecture à distance des compteurs électriques.
