1. A process fluid multivariable measurement system comprising:
a thermowell configured to couple to a process fluid conduit and extend through a wall of the process fluid conduit;
a temperature sensor assembly removably disposed within the thermowell, the temperature sensor assembly having at least one temperature sensitive element disposed therein;
a pressure sensor assembly coupled to the thermowell, the pressure sensor assembly that is a having at least one pressure sensitive element disposed therein that is fluidically isolated from the process fluid conduit; and
transmitter circuitry communicatively coupled to the temperature sensor assembly and the pressure sensor assembly, the transmitter circuitry 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; and
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;
wherein the transmitter circuitry is configured to communicate the temperature measurement output and the pressure measurement output using a process communication protocol.
