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.

Abstract: A temperature sensor includes a temperature probe, an adapter, a resilient device, and a visual indicator. The temperature probe includes a temperature sensing device disposed at a temperature probe tip. The adapter surrounds a portion of the temperature probe such that the temperature probe is movable within the adapter in a lengthwise direction. The adapter includes a physical reference. The resilient device is adapted to produce a force between the adapter and the temperature probe. The force being variable based on a position of the temperature probe within the adapter. The visual indicator is disposed on a surface of the temperature probe. Alignment of the visual indicator with the physical reference corresponds to a desired force produced by the resilient device.
