Oil and gas employ infrared technologies for condition monitoring and predictive maintenance. However, infrared technology does not need physical contact with the monitored machinery, which has various advantages over visual inspection and other approaches. IR thermography measures a component's temperature as heat (thermal radiation) flows through, from, or toward it. IR thermography is sometimes called thermal imaging, infrared thermometry, and thermal testing. Today's post explains IR thermography. Let's start with a brief introduction to IR thermography. Thermography Infrared Meaning Infrared thermography "views" and "measures" an object's infrared radiation. It uses an infrared camera. The human eye cannot see thermal or infrared light because its wavelength is too long. This electromagnetic spectrum region represents heat. Everything above absolute zero emits infrared radiation, not visible light. Ice emits infrared radiation. Our eyes can...
