Abstract
A beam-type strain gage pressure transducer is disclosed having strips of piezo-resistive material supported on a sensing beam, one being subject to compression and another to tension in response to applied pressure. The beam structure may be made by screw machine techniques to form a beam integral with a circular base structure. A highly flexible diaphragm permits force generated by application of pressure to be transmitted entirely to the beam. Components and construction are suited to high production and automated assembly techniques.
