Infrared Thermography Services
1. WHAT IS IR ?
Infrared thermography is the technique of using a non-contact & non-destructive Infrared Scanning Camera to detect invisible Infrared thermal radiation of objects, and recording these pictures as thermal images called "Thermograms" to assist in identifying potential equipment failures.
Infrared radiated energy is emitted by all objects, animate or otherwise, having a temperature above absolute zero.
Amount of energy emitted depends upon how hot the object is and how well it can emit energy.
2. HOW IS IT MEASURED ?
Since Infrared energy is not visible to the human eye, detection requires a physical device to convert the IR to a visible image.
The Thermographic Camera utilizes a system to focus the IR energy onto an IR sensitive detector which is sensitive to radiation within the Infrared Wavelength between 2 - 14 um.
The detector converts the IR energy to a voltage signal, which is in turn, imaged into a TVlike display. These images would then be recorded onto Disk or memory chips.
The Temperature range of a typical Infrared Camera is –15° C to 1500° C in 0.1° C steps.
Analysis of the Thermal Images would be carried out on Computer using specialised software. As a general rule, the following temperature differentials for electrical connections is recommended:
||MAXIMUM TIME TO REPAIR
|5 to 10°C
|11 to 20°C
||As soon as possible
||Next scheduled shutdown (but < 12 mths.)
|21 to 29°C
