Abstract

A thermowell assembly for measuring a process temperature includes an elongate thermowell having a proximal end and a distal end. A bore extends between the two ends with the thermowell assembly configured to extend into a process fluid. An infrared sensor detects infrared radiation from the distal end through the bore of the thermowell and responsively provides a sensor output. A configuration is provided in which infrared radiation received by the infrared sensor from a wall of the bore is reduced and or radiation received from the distal end of the bore is increased.
