Abstract
A radiant energy sensor is adapted to detect radiant heat energy incident on a surface. The energy sensor has a body portion with a pair of sides. A temperature sensor is located on each side of the body portion. In use the body portion is mounted on the surface such that one of the sensors is located between the body portion and the surface, thereby being masked by the body portion from heat energy otherwise incident on the surface.
