1、 About ThermographyThermography is the use of 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; its the part of the electrom
2、agnetic spectrum that we perceive as heat. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared. The higher the objects temperature, the greater the IR radiation emitted. Infrared allows us to
3、 see what our eyes cannot.Infrared thermography cameras produce images of invisible infrared or heat radiation and provide precise non-contact temperature measurement capabilities. Nearly everything gets hot before it fails, making infrared cameras extremely cost-effective, valuable diagnostic tools
4、 in many diverse applications. And as industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.How Do Infrared Cameras WorkAn infrared camera is a non-contact device that detect
5、s 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 pe
6、rformance, but also identify and evaluate the relative severity of heat-related problems. Recent innovations, particularly detector technology, the incorporation of built-in visual imaging, automatic functionality, and infrared software development, deliver more cost-effective thermal analysis solut
7、ions than ever before.Why measure temperature?Finding a problem with an infrared camera is sometimes not enough. In fact, an infrared camera image alone without accurate temperature measurements says very little about the condition of an electrical connection or worn mechanical part. Many electrical
8、 targets are operating properly at temperatures that are significantly above ambient. 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 professi
9、onals to make well informed 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 w
10、ill 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
11、 on standard PC platformsWhy Use Infrared?A picture says a thousand words; infrared thermography is the only diagnostic technology that lets you instantly visualize and verify thermal performance. FLIRs infrared cameras show you thermal problems, quantify them with precise non-contact temperature me
12、asurement, 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. And today,
13、 no one would argue that infrared thermography is the most effective proven predictive maintenance (PM) technology available to quickly, accurately and safely locate problems prior to failure. In June 2001, Maintenance Technology magazine reported a $4 (USD) return on investment in for every $1 (USD
14、) spent on infrared inspection. 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. But using infrared images to find a problem is somet
15、imes not enough. In fact, an infrared camera image without an accurate measurement says very little about the condition of an electrical connection or worn mechanical part. And, an IR survey without a simple, fast way to report and analyze inspection results provides no ability to make timely repair

FLIRs ThermaCAM infrared cameras and Reporter software not only quickly locate problems, their non-contact precision temperature measurement and analysis capabilities instantly deliver the answers you need to understand what repair action to take, and when. Whether youre looking at buildings or hybrid circu
