Thermography can be described as a

temperature picture

Every Colour represents a temperature.

This temperate picture will give you an in depth idea of what is happening to the component that you are looking at.

What is Thermography

• All objects emit infrared radiation .

• With a Thermal Imager we measure the amount of radiation emitted by an object by electromagnetic waves

• Visual Images are reflected whereas Thermal Images are emitted.

• Radiation increases with temperature. The more the object

radiates, the higher the temperature.

• Temperature is a calculation of how much energy is being radiated by an

object.

• The Thermal Camera serves as the receiver and only measures surface

temperatures

How will a Thermographer measure up when he is asked what Thermography is?

A qualified Thermographer with the necessary experience will be able to stipulate between the various testing methods, the accuracy of the results and providing consistent results through

understanding the test method.

Collection of data : It is about more than taking pretty

pictures

Cost effective Evaluation Understand what you see The Correct interpretation Measurements Detect changes Operating conditions : Potential failure Information

Thermography Training

How to establish inspection routes How Hot is to Hot? Probability of failure Consequence of the failure Accurate (Radiometric)

Measurements The Influence of Electrical Load What is the Powerful effect of

A thermal imaging camera is only as good as the operator

WHY do you need to attend Certified Thermography Training ? It is not just about taking a pretty picture By attending Certified Training you will be provided with valuable information on

HOW to interpret what they see .

HOW to solve many costly maintenance problems in their work environment

A Certified Thermography course is an important part of becoming a skilled , practising Thermographer The American Society of Non-destructive Testing has created qualification and certification standards for

Thermography . Professional certification adheres to industry accepted and proven best practices for training and qualifying thermographers internationally.

Differentiate a qualified thermographer from a camera operator.

I can see a hot spot

But I can’t measure it

………So I move closer and FOCUS

Or I Change my lens

Or Use the correct camera

for the application

Level 1 is the most basic

requirement anyone handling a thermography camera should have.

Level 1 certification requires the

candidate to have completed 31 hours of training, have at least 210 hours of practical experience and pass a three-part examination which includes a practical evaluation of the candidate’s ability to handle a camera.

Ultimately the demonstrated skill and knowledge along with documented training and experience required for a person to properly perform the duties is an essential part of a fully functional and effective thermography program.

Comprehensive Knowledge, skills

and Know how, combined with a documented training programme, will empower the Thermographer to become fully functional, and deliver truly effective solution
