Abstract
An explosion-proof thermal imaging system is provided. The system include an explosion-proof housing having a window that is configured to allow thermal radiation therethrough. An infrared camera is positioned within the explosion-proof housing and is disposed to receive and image thermal radiation that passes through the window. An emissivity target is disposed within a field of view of the infrared camera, but on an opposite side of the window from the infrared camera. A temperature sensor is operably coupled to the infrared camera and is configured to provide an indication of temperature proximate the emissivity target.
