Temperature is one of
the important parameters to tell the condition of
internal process, material and even quality of the
desired output. A qualitative but accurate conclusion
can be drawn by observing the temperature profile of any
surface. On the other hand higher temperature also
indicates obvious loss of energy in the form of heat.
Therefore temperature monitoring would give ample
indication of the condition of the material, process
quality and explore the possibility of energy
conservation avenues.
In recent years, many
temperature monitoring techniques have been in use in
our industries. These techniques find their application
based on the measurable temperature range, sensitivity
and ease in application. A comparison of various typical
techniques has been given in table no. 1.
With the on-line
condition monitoring technology becoming an inevitable
part of maintenance strategy in today’s scenario,
non-contact type temperature monitoring methods have
become more popular. Infrared Thermography is such a
non-contact type technique which provides a fast,
reliable and accurate temperature profile of any
material surface.
This paper deals with
various application of infrared thermography including
the justification of energy saving potential in many
cases.
