<p>A process variable transmitter (36) for measuring a pressure of a process fluid includes a first inlet (386) configured to couple to a first process pressure (P) and a second inlet (386) configured to couple to a second process pressure (P). A differential pressure sensor (56) couples to the first and second inlets (386) and provides an output related to a differential pressure between the first pressure and the second pressure. A first pressure sensor (304A) couples to the first inlet (386) and provides an output related to the first pressure. Transmitter circuitry (72) 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.</p> |
