Patent ID: 8033175

Claim:
A multivariable process fluid pressure transmitter comprising: an electronics module; a sensor module coupled to the electronics module; a differential pressure sensor disposed within the sensor module and being operably coupled to a plurality of process fluid pressure inlets; a static pressure sensor disposed within the sensor module and being operably coupled to at least one of the process fluid pressure inlets; a first temperature sensor disposed within the sensor module and configured to provide an indication of a temperature of the differential pressure sensor; a second temperature sensor disposed within the sensor module and configured to provide an indication of a temperature of the static pressure sensor; measurement circuitry operably coupled to the differential pressure sensor, the static pressure sensor and the first and second temperature sensors; a processor coupled to the measurement circuitry and configured to provide a compensated differential pressure output based on a measurement of the differential pressure sensor and the first temperature sensor, and to provide a compensated static pressure output based on a measurement of the static pressure sensor and the second temperature sensor.
