The invention disclosed herein is a pressure transducer utilizing a Hall effect sensor to detect the displacement of the transducer's diaphragm. The pressure transducer includes a power supply to draw current from a 4mA to 20mA current loop and deliver current to the Hall effect sensor at an average rate of 4mA or less.
La présente invention concerne un transducteur de pression muni d'un capteur d'effet de Hall pour déceler le mouvement de la membrane du transducteur. Ce dernier comprend un bloc d'alimentation en courant provenant d'une boucle de courant de 4mA à 20mA, afin d'acheminer ce courant au capteur à effet Hall à un courant de 4 mA ou moins.
