ABSTRACT:
A pressure transducer includes an electromagnetic drive coil which vibrates a thin walled cylinder at a natural vibrational mode. A capacitor unit senses the vibrational frequency of the cylinder and gives an output signal corresponding to the pressure differential between a fluid contained within the cylinder and a vacuum reference that is maintained adjacent to the exterior surface of the cylinder. Electric heaters maintain a constant operating temperature of the transducer.
