INFRARED THERMOGRAPHY INQUIRY FORM


What is Infrared Thermography?

Infrared is an invisible portion of the light spectrum extending from 0.75 to 1000 microns.  All objects warmer than absolute zero (0 Kelvin or -273.15°C) emit energy somewhere within that range.  The warmer the object, the brighter is its image in thermal camera. In the color spectrum, the white is hotter & black is colder. Only Infrared Cameras can sense & display the surface temperatures of any object. The Thermography is evolving daily and being deployed in many unusual applications like Defence, Remote sensing, Green building applications, Predictive maintenance tool, Health monitoring of Electrical & Mechanical equipments etc. Thermography used to be expensive, difficult, and primarily used by large industrial facilities and the military. These days, it’s become much more affordable, more accurate; more broadly applied and even professional qualified thermographers of international standards are also available.

Who does the Infrared Thermography?

Infrared Thermography is a very specialized field and should only be done by a Trained and experienced Thermographer. A thermographer is a thermal evaluator and imaging expert. He or she will have a solid understanding of heat transfer laws, thermodynamics and behaviour of heat energy besides, expertise in thermal image capturing and correcting the effects of emmisivity & reflections. A thermographer also has good knowledge of the other non-destructive testing tools to evaluate the equipment health.
Why should Infrared Thermography be used?

As the old saying goes, “a penny saved is a penny earned”. In recent years, the idea of infrared thermography is gaining popularity in many industrial sectors. The objective is to develop cost effective programs that save the clients’ money and minimizes downtime. Mechanical, Process & Electrical components give off heat, so, the surveys seek out heat patterns and temperature differentials. comparison of temperatures/heat is vital in interpreting the situation and arrive at the root cause of the problem. Thermography helps in early identification & some times quantification of the potential problem area. Breakdowns and Downtime is a force to reckon with in all industries. Minimizing downtime is essential to running an efficient operation. Thermography is very effectively used to give early warnings on equipment/component failure and also helps to avoid excessive preventive maintenance. It optimizes the maintenance costs and also Minimizing Downtime.
