A process variable transmitter for measuring a pressure of a process fluid includes a first inlet configured to couple to a first process pressure and a second inlet configured to couple to a second process pressure. A differential pressure sensor couples to the first and second inlets and provides an output related to a differential pressure between the first pressure and the second pressure. A first pressure sensor couples to the first inlet and provides an output related to the first pressure. Transmitter circuitry provides a transmitter output based upon the output from the differential pressure sensor and further provides enhanced functionality based upon the output from the first pressure sensor. |
