Disclosed is a pressure sensor, for example for a domestic central heating boiler, comprising a rolling diaphgram (15) that adjusts its position in dependence upon the fluid pressure admitted through a pressure port (5). The diaphgram acts against an actuator (7) which adjusts the position of a wiper (20) of a thick film potentiometer, to provide an output voltage in dependence on the admitted fluid pressure. The potentiometer may be calibrated at the factory by rotating an adjustment cap (11) of the actuator (7), which has claw- like projections in engagement with outward projections of part-helical form on a body part (8) of the actuator. There is a one-to-one axial position relationship between the actuator (7) and the wiper (20).

L'invention concerne un capteur de pression, par exemple destiné à une chaudière de chauffage central à usage domestique, le capteur de pression comprenant une membrane à enroulement (15) réglant sa position en fonction de la pression fluide à l'admission par un orifice de pression (5). La membrane agit contre un organe d'actionnement (7) qui règle la position du curseur (20) d'un potentiomètre à film épais, afin de produire une tension de sortie en fonction de la pression fluide à l'admission. On peut calibrer le potentiomètre à l'usine en tournant un couvercle de réglage (11) de l'organe d'actionnement (7) doté de saillies en forme de pinces coopérant avec des saillies vers l'extérieur d'une forme partiellement hélicoïdale sur une partie de corps (8) de l'organe d'actionnement. Il existe un rapport un à un de position axiale entre l'organe d'actionnement (7) et le curseur (20).
