What is IR Thermography
IR Thermography is the technique of producing
pictures called thermograms, from the invisible thermal
radiation that objects emit. This is a non-contact means
of identifying electrical and mechanical components that
are hotter than they should be, often an indication of impending
failure, it also indicates excessive heat loss which is
normally a sign of faulty or inadequate insulation.
What can IR Thermography
do for me?
IR Thermography is playing an increasingly
important role in facility maintenance, Non Destructive
Evaluation (NDE) and predictive maintenance programs. Thermography
detects hidden problems and allows for corrective action
before costly system failures. Using IR Thermography can
reduce downtime by avoiding unplanned shutdowns, by assisting
in the timing and planning of scheduled maintenance. Thus
allowing production time to be increased by maximising equipment
availability. Thermographic equipment can also provide valuable
data in building maintenance, common applications are:
Predictive Maintenance
Predictive maintenance programmes are by their
nature very difficult to manage.
Todays high performance thermographic equipment provides
an excellent tool for predicting equipment failure, especially
as it has been proved that thermal characteristics change
gradually prior to failure. Digital Images from a survey
contain reference signals that when decoded by our software
allows for more detailed thermal analysis and archiving
to a standard database. Image subtraction (where one image
can be subtracted from a standard or previously saved image
of an object) quickly highlights all temperature differences.
More in depth measurement techniques such as histograms
or temperature gradients are used in applications where
trend analysis is required.
Why Should I use IR Thermography?
Todays Companies are finding that strict
regulations regarding quality, safety and manufacturing
standards together with a constant battle to maintain productivity
levels can become a drain on precious resources. Managers
are becoming more aware of technological advances in equipment,
whose practical applications can assist them in meeting
statutory and production requirements, thus releasing valuable
resources to the company. Current methods in use are slower,
labour intensive and in most cases will require some interruption
to the process being inspected. IR Thermography is a faster
and totally non-intrusive means of inspection and as a result
is a less expensive option than traditional inspection methods.
