Abstract:
A process variable transmitter system for sensing a first pressure at a first location and second pressure at a second location, includes a first transmitter having a first pressure sensor configured to sense the first pressure and first analog output stage coupled to the first sensor configured to provide an analog output signal related to the first pressure. A second pressure transmitter includes a second pressure sensor configured to sense the second pressure and spaced apart from the first pressure sensor. A second analog output stage provides an analog output related to the second pressure. An analog processing stage provides a processed output related to the first and second pressures. A two-wire output is configured to provide an analog current output on a two-wire process variable loop based upon the processed output.
