Abstract: A process fluid multivariable measurement system is provided. The multivariable measurement system includes a thermowell configured to couple to a process fluid conduit and extend through a wall of the process fluid conduit. The multivariable measurement system also includes a temperature sensor assembly disposed within the thermowell, the temperature sensor assembly having at least one temperature sensitive element disposed therein. The multivariable measurement system also includes a pressure sensor assembly coupled to the thermowell, the pressure sensor assembly having at least one pressure sensitive element disposed therein. The multivariable measurement system further includes transmitter circuitry, communicatively coupled to the temperature sensor assembly and the pressure sensor assembly, configured to receive a temperature sensor signal from the at least one temperature sensitive element and responsively generate a temperature measurement output based on the temperature sensor signal. The transmitter circuitry is further configured to receive a pressure sensor signal from the at least one pressure sensitive element and responsively generate a pressure measurement output based on the pressure sensor signal.
