ABSTRACT:
A tensioned bellows pressure transducer having a pressure chamber [40], an elastic vibrating member [50], an electromagnetic coil [60] a linkage [33], a rigid body [30], a body extension [35], and a pressure deformable member [22] defining in part a reference chamber [20]. In preferred embodiments, the pressure deformable member is a bellows. Bellows [22] is attached at bellows fixed end [23 to rigid body [30] and is deformable in response to a difference between a bellows internal reference pressure p.sub.0 and any pressure p.sub.1 external to bellows [22], such as in pressure chamber [40]. Elastic vibrating member [50] is connected at a first end to linkage [33]. Linkage [33] projects rigidly from an interior face of bellows free end [24] and vibrating member [50] is connected to linkage [33] at a distance d.sub.2 from free end [24], and is connected to body extension [35] at a distance d.sub.1 from free end [24], where d.sub.1 is less than d.sub.2. Thus tensile stress in elastic vibrating member [50] is increased by compressional deformation of bellows [22], and member [50] restrains deformation of bellows [22] through tension loading of bellows [22].
