ABSTRACT:
A pressure transmitter for sensing fluidic pressure to produce an indication that is converted into a signal for transmission to a remote station. The transmitter includes a sensor constituted by a diaphragm which seals a chamber in a meter body subject to fluid pressure, the diaphragm being axially dilated in accordance with the applied pressure. Anchored on the diaphragm is an upstanding force beam which is pushed thereby in the axial direction. A range spring which is offset with respect to the axis of the beam is connected between an intermediate point on the beam and the meter body. The spring acts to constrain axial motion of the beam, whereby when the diaphragm is dilated by fluidic pressure, the beam is caused to deflect to an extent determined thereby. A motion detector is operatively coupled to the upper end of the beam to convert the deflection thereof into a corresponding signal for transmission.
