  • Patent number: 4206437
    Abstract: A movable member pressure transducer is disclosed which incorporates various thermal and manufacturing tolerance compensation features. These include a temperature compensating bimetal interposed between the movable member and the pressure sensing aneroid; a threaded engagement between a potentiometer wiper contact and a movable member used to generate an electrical signal corresponding to the position of a lower member, with the threaded engagement allowing adjustment of the zero position of the wiper contact with respect to the potentiometer resistive element; a cantilevered spring is mounted in contact with the free end of the movable member. The cantilever spring mounted in a holder is constructed of a material selected to have a coefficient of thermal expansion compensating for variations in sensitivity due to temperature changes by corresponding changes in the effective lever arm of the cantilever spring by shifting the point of contact of the end of the movable member with the cantilever spring.
