1. A pressure transducer comprising:

  • a housing defining an opening;

    a diaphragm formed by an elongated member mounted in the opening in the housing;

    the elongated member being free to flex in response to fluid pressure applied to the surface of the elongated member;

    means for measuring deformation of the elongated member;

    a pair of electrodes in electrical connection with the means for measuring deformation of the elongated member; and

    an elastic material sealing the gap between the housing and the elongated member to create a seal for the diaphragm, the housing being adapted for a source of reference fluid pressure to be applied on one side of the diaphragm against the elongated member, the housing being further adapted for a source of fluid pressure to be measured to be applied against the elongated member on the other side of the diaphragm.
