Thermography is using an infrared imaging and measurement camera to see and measure thermal energy emitted from an object. Thermal or infrared energy is light that is not visible because its wavelength is too long to be detected by the human eye; it's the part of the electromagnetic spectrum that we perceive as heat. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. The higher the object's temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot. Infrared thermography cameras produce images of invisible infrared or "heat" radiation and provide precise non-contact temperature measurement capabilities.

As nearly everything gets hot before it fails, infrared cameras are cost-effective, valuable diagnostic tools in many diverse applications.
An infrared camera is a non-contact device that detects infrared energy (heat) and converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations. Heat sensed by an infrared camera can be very precisely quantified, or measured, allowing you to not only monitor thermal performance, but also identify and evaluate the relative severity of heat-related problems. This is the sum total of infrared thermography.
An infrared camera image without accurate temperature measurements tells very little about the condition of an electrical connection or worn mechanical part. An infrared image without measurement can be misleading because it may visually suggest a problem that does not exist. Infrared cameras that incorporate temperature measurement allow predictive maintenance professionals to make judgments about the operating condition of electrical and mechanical targets. Temperature measurements can be compared with historical operating temperatures, or with infrared readings of similar equipment at the same time, to determine if a significant temperature rise will compromise component reliability or plant safety.
Digital image storage, available on most FLIR Systems infrared cameras, produces calibrated thermal images that contain over 78,000 independent temperature measurements that can be measured at any time with FLIR Systems infrared software products on standard PC platforms.
A picture says a thousand words; infrared thermography is the only diagnostic technology that lets you instantly visualize and verify thermal performance. FLIR's infrared cameras show you thermal problems, quantify them with precise non-contact temperature measurement, and document them automatically in seconds with professional easy-to-create IR reports.
Nearly everything that uses or transmits power gets hot before it fails. Cost effective power management is critical to maintaining the reliability of your electrical and mechanical systems. Finding and fixing a poor electrical connection before a component fails can save you the much greater costs associated with manufacturing downtime, production losses, power outages, fires and catastrophic failures.
