Abstract

Circuit électrique pour des sondes de pression et de température permettant des relevés à distance sans influence de la résistance électrique des conducteurs. Dans ce circuit, une sonde de pression 3 et une sonde de température 1 sont montées en série dans un circuit c1-c7 d'alimentation en courant continu; les conducteurs reliés aux bornes des sondes et aux autres points de prélèvement des signaux fournissent des signaux de tension à distance des sondes, en utilisant un câble ne comportant qu'un nombre minimal de conducteurs, en l'espèce sept conducteurs.
