Abstract
A pressure transducer comprises a bellows as the pressure sensing element and a variable inductance coil whose inductance is made to vary as a function of pressure sensed by the bellows. Motion is transmitted between the bellows and a plunger associated with the coil by means of a bent lever mechanism. The mechanical advantage of the bent lever is adjustable, after assembly of the transducer, to set the span to a desired value.
