30 Dec What is Infrared Thermography?

Thermal/Infrared Testing, or infrared thermography, is used to measure or map surface temperatures based on the infrared radiation given off by an object as heat flows through, to or from that object. We can use the temperature to predict or diagnose a potential failure. This temperature is directly related to the materials, the thermal energy level and heat transfer rate. Thermal imaging can be used to detect corrosion damage, delamination, disbonds, voids, inclusions.

Why Infrared?

All matters with a temperature greater than absolute zero emits thermal radiation. When the temperature of a body is greater than absolute zero.

Where can we use IR Thermography?

For this high temperature steam boiler, thermal imaging shows that that the insulation on the inside of this vessel has deteriorated. Only infrared imaging provides a fast, safe, non-contact method of inspection! This thermogram shows the hot water radiant coils under a tile floor. Thermal imaging accurately located the exact position of each radiant coil, confirmed there were no leaks and identified safe locations to drill fixture mounting holes.
