IR Inspection Windows for Electrical System Reliability
An Infrared Inspection Window is used to separate environments of differing pressures or temperatures while allowing light energy at a specified electromagnetic wavelength to pass between the two environments. They must meet the strength and environmental requirements for the type of equipment in which they are fitted, as well as be compatible with the infrared inspection equipment being used.
IR Inspection Windows enable the following:
- Collection of real-time, condition status data on critical electrical systems...
