Thermography is an inspection technique that is able to give immediate results and cost savings to clients. The applications are almost limitless for most industry types. Seeing the problem is normally easily done, however this is only part of the process, it is also necessary to interpret the results. In addition the high capital cost of the equipment can make one off requirements uneconomic. Using Velosi to complete the service is a cost effective way to ensure that the inspection is carried out by qualified and experience personnel at a reasonable cost using the most up to date equipment available.

“Nearly everything gets hot before it fails”

Thermography 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; 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. Even very cold objects, like ice cubes, emit infrared. 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.

Here an electrical circuit breaker is clearly shown as overheating indicating a problem such as a poor connection, an internal fault, or corrosion.

High definition Thermographic cameras have migrated into other fields as varied as engineering, medicine and archaeology. More recently, the lowering of prices have helped fuel the adoption of infrared viewing technology. Advanced optics and sophisticated software interfaces continue to enhance the versatility of this diagnostic tool. As industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.

In modern applications, equipment failures are usually preceded by an abnormal temperature pattern, and this temperature rise can be easily detected by an infrared thermographic inspection.

The advantages are that it can reduce unplanned down-time, maintenance costs, and also improves production, equipment life, and plant safety.

One of the advantages of this non-destructive and non-contact technique is the ability to detect faults in time without the necessity to shut down the plant.

The most common applications:

Temp measurement.

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 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 professionals 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 will compromise component reliability or plant safety.
Digital image storage on our equipment produces calibrated thermal images that contain over 78,000 independent temperature measurements that can be measured at any time with infrared software products on standard PC platforms.
