Why Infrared Thermography?
As a “thermographer”, taking thermal images may seem easy: simply “aim, focus, shoot” – and you get your thermal image! However, the true value lies in what one understands about the object of interest, how it operates, the heat transfer within and to the surface of the object, how to adjust the camera to include maximum thermal detail. Most importantly, it boils down to the Thermographer’s ability to analyse the thermogram, interpret the thermal data appropriately to identify thermal anomalies as existing or potential problems or faults. Finally at end, document and present the work done and ﬁndings in a clear and concise report.
No, this is no simple task of just “aim, focus and shoot”, as most camera manufacturers and vendors would reiterate to you.
Many thermographers still grapple with the issues of
- Reﬂected images (that are easily confused with or mistaken as a “hot-spot”) and
- the impact of “emissivity” of different objects within thermal images.
Equally worrisome is that many “certiﬁed” thermographers were taught the “old-school” “DeltaT” approach towards analysis of thermal data (i.e. simply taking the temperature differential between the lowest and hottest spot – as a means of determining the “severity” of an thermal anomaly). This is not an appropriate basis, especially within the context of electrical IR applications, by which our Institute has strenuously distance itself from. At IIRT’s training, you are assured of our full guidance on the appropriate approach!
“The use of Infrared Thermography (IRT) using measurements of surface temperature to monitor condition and diagnose faults in civil, mechanical and electrical systems has become a key activity in predictive maintenance programmes for most industries. The effectiveness of these programmes depends on the capabilities of individuals who perform the measurements and analyse the data.
Certiﬁcation to this speciﬁcation will provide evidence of the qualiﬁcation and assessment of individuals to perform Infrared Thermography measurements and analysis using appropriate sensors and equipment. (UK) BINDT- PCN CM/GEN.
At IIRT, we strive to instil the need for being alert, observant and maintaining an inquisitive mind-set in each participant. We structure our tutorials with an extensive mix of video presentation and illustrative real-world thermal images that will help participants gain effective understanding on each topic of study. Special guidance is attention is rendered on the Do’s and Don’t’s in Report Writing, in preparing a clear, concise and meaningful report.
