<p>A pressure transmitter is provided. The pressure transmitter includes a pressure sensor including a pair of process fluid pressure ports each having a deflectable diaphragm. A first variable capacitor is disposed within the pressure sensor and has a capacitance that varies with differential pressure between the process fluid ports. A second variable capacitor is disposed within the pressure sensor and has a capacitance that varies with line pressure.</p> |
