Abstract
A pressure transducer 10 is disclosed wherein a bellows 11 is expanded by an external pressure applied at pressure port 16. The force created by external pressure applied to bellows 11 is mechanically transferred to one end of a vibrating elastic member 14 by axial displacement of saddle 13. A change in external pressure is thereby read as a change in resonant frequency of elastic member 14.
