Abstract

See full text

A process fluid temperature measurement system includes a thermowell configured to couple to a process fluid conduit and extend through a wall of the process fluid conduit. A temperature sensor assembly is disposed within the thermowell and includes a first temperature sensitive element and a second temperature sensitive element. The first temperature sensitive element is disposed within the thermowell adjacent a distal end of the thermowell. The second temperature sensitive element is spaced apart from the first temperature sensitive element along a spacer having a known thermal conductivity. Transmitter circuitry is coupled to the first and second temperature sensitive elements and is configured to perform a heat flux calculation to provide a process fluid temperature output.
