Abstract
The temperature sensor includes a light pipe and a cap configured to be positioned within a flow path of a fluid. The cap includes a material configured to emit radiation based on a temperature of the material. A light source is configured to emit light through the light pipe toward the cap, and a detector is configured to receive the radiation emitted by the material of the cap and to generate a first signal based on the received radiation emitted by the material. The detector is configured to generate a second signal indicative of a light-induced delta temperature caused by the light emitted toward the inner surface of the cap. The system also includes a controller configured to determine a condition of the temperature sensor based on the first signal and the second signal.
