1. A process variable transmitter system for sensing a first pressure at a first location and second pressure at a second location, comprising:

  • a first process variable transmitter having;

    a first pressure sensor configured to sense the first pressure; and

    a first analog output stage coupled to the first sensor configured to provide a first analog output signal related to the first pressure;

    a second process variable transmitter having;

    a second pressure sensor configured to sense the second pressure, the second pressure sensor spaced apart from the first pressure sensor;

    a second analog output stage configured to provide a second analog output related to the second pressure;

    an analog processing stage configured to provide a processed output related to the first and second pressures; and

    a two-wire output circuitry configured to provide an analog current output on a two-wire process control loop based upon the processed output.
