A pressure transmitter (10) is provided. The pressure transmitter (10) includes a pressure sensor (60) including a pair of process fluid pressure ports (14, 16) each having a deflectable diaphragm (70, 72). A first variable capacitor is disposed within the pressure sensor (60) and has a capacitance that varies with differential pressure between the process fluid ports (14, 16). A second variable capacitor is disposed within the pressure sensor (60) and has a capacitance that varies with line pressure. |
