Abstract

1498287 Pressure transducers DUCELLIER ET CO 4 July 1975 [9 July 1974] 28179/75 Heading G1N [Also in Division H1] A fluid pressure transducer comprises a diaphragm 4, Fig. 1, attached by a spring-loaded arm 6 to a lever 7, pivotted at 8 and carrying a sliding contact 11 for a resistance track 12, whereby the pressure on the outer surface of diaphragm 4 determines the angular displacement of the lever 7 and the voltage tapped off the potentiometer 12. A toothed eccentric 15 enables adjustment to be made of the tension in loading spring 5 and of the initial position of the slider 11 on the track12; the pressure between the latter is adjusted by rotation of the slider carrier 10 about a locking screw 20.
