Thermography
Thermal Imaging or
Thermography is the process of using a special
camera designed to look only for heat by way of
Infra Red (IR) energy waves.
Unlike light waves, IR is invisible to the naked eye
therefore so is heat. Potential problems can often
be found due to an excess of heat being released by
the component, even those which would normally
produce some heat when performing at their optimum
level. |
 |
|
 |
If undetected these
problems can lead to failure. These failures can
result in expensive production loss or downtime and
in the most extreme case can lead to fire.
Because heat cannot be seen and certainly any
differences between normal temperature and raised
levels due to possible malfunction could not be
picked up by even the most highly skilled engineer,
Thermography makes perfect sense to use as part of a
normal maintenance schedule. |
Thermography is a
non-contact and non-destructive type of testing, and
is an invaluable resource for predictive
maintenance. Complete surveys can be carried out
with no interruption to normal or critical
production.
A regular programme of Thermal Imaging as part of
routine maintenance can highlight potential problems
long before any event. As a result any required
repairs can be planned for in terms of both time and
budget. |

 |
By using an infra red
camera, we can analyse the
temperature of individual components
within any industrial equipment.
Normally the survey
can be performed without having to
suspend production (therefore having
no impact on up-time).
Where the
thermography engineer identifies a
component that appears to be
overheating then a picture of the
component is recorded. On completion
of the survey all data is downloaded
into the reporting software where
faults and recommendations are
documented. A copy of the report
is then supplied to the customer in
either paper format or on CD-ROM. |

Example 1 -
Bearing
appears to be overheating. This would be reported to the site
engineer with recommendation for further inspection during planned
maintenance. |
 |
Example 2 - Localised heating on red line,
could be causing internal
contacts to overheat, recommend
inspection during planned
maintenance. |
