Abstract: The subject matter disclosed herein relates to temperature monitoring devices, and more specifically to surface temperature monitoring devices (e.g., surface temperature loggers, surface temperature sensors, surface thermal probes). In an embodiment, a system includes a temperature monitoring device configured to measure a temperature of a surface. The temperature monitoring device includes a housing and a thermal sensor disposed in the housing. The temperature monitoring device also includes a thermal pad disposed on a measurement face of the housing, wherein the thermal pad is configured to provide a high-thermal conductivity path between the surface and the temperature monitoring device.

Abstract: A system includes a sensor body that has a folded optical waveguide configured in a “U” shape, wherein the waveguide is configured to convey infrared energy from one end of the waveguide to the other end of the waveguide.
