Abstract
An electronic differential-pressure transmitter responsive to a difference between two pressure values to generate an output signal proportional to differential pressure for transmission to a remote station for acuating indicator or process control equipment. The transmitter is of the open-loop type that includes a pivoted force-beam to the lower end of which is applied an input force dependent on differential pressure, the resultant deflection of the beam being sensed by a motion detector coupled to the upper end thereof to produce the output signal.
