DIFFERENTIAL PRESSURE TRANSMITTER WITH COMPLIMENTARY DUAL ABSOLUTE PRESSURE SENSORS
摘要
<p>A process variable transmitter for measuring a pressure of a process fluid includes a process coupling having a first port configured to couple to a first process pressure and a second port configured to couple to a second process pressure. A differential pressure sensor is coupled to the first and second ports and provides an output related to a differential pressure between the first pressure and the second pressure. First and second pressure sensors couple to the respective first and second ports and provide outputs related to the first and second pressures. Transmitter circuitry is configured to provide a transmitter output based upon the output from the differential pressure sensor and/or the first and/or second pressure sensors. Additional functionality is provided by the transmitter using the sensed first and/or second pressures.</p>
