Abstract: A thermographic temperature sensor includes a probe having a housing and a light pipe disposed within the housing. The light pipe includes a thermographic phosphor that may phosphoresce in response to absorbing light. The phosphorescence by the thermographic phosphor is representative of a temperature of a fluid in contact with the probe, and a surface area of the light pipe is not in contact with an inner surface of the housing.
