The mounting position is situated on a flange behind the observation window outside the furnace.
The cooling of the system is performed by a heat exchanger (water-cooling system). The optical lens was developed so that only the minimal amount of infrared radiation needed reaches the camera. In order to keep the probe environment free from contaminants it is purged with nitrogen gas. High quality materials and components are used throughout to ensure durability even in the harshest of environments found within heat treatment companies. Glass fibre is used for video transmission to minimise or avoid electronic interference of the signals.
