Thermographic inspection, the latest service from Celsius
From experience Celsius knows that the normal regular and preventive inspections of machines and installations do not always offer the desired results. Premature faults result in expensive damage and repairs, unplanned downtime and inadmissible production loss. This is why from now on Celsius is offering its clients the option of having specific (regular) thermographic inspections carried out.
Prevention and detection of faults
Machine and installation maintenance using thermography as a diagnostic tool is an excellent way of detecting at an early stage whether something is wrong with crucial parts of a machine or installation. A faulty bearing, insufficient lubrication or poor product flow quickly lead to a raised temperature. Celsius aims to provide extra added value for its clients and to think collaboratively with them in a continuous improvement process so that clients can save costs, improve quality and increase productivity in their work.
Thermography is a measurement method which charts the temperature. Temperature differences are charted using a thermographic camera (infrared). By analysing these temperature differences it is possible to work towards detection. In part thermography also makes it possible to look 'under' the surface of a material. Of course it does not actually look through or under a material, but by accurately measuring the differences in the surface temperature it is possible to gain a picture of what is going on under a surface.
A thermographic camera is equipped with optics for infrared imaging and a detector that analyses the wavelength. Its operation is based on Wien's law. The camera provides a thermogram, a visual representation of the prevailing temperatures. A thermogram is like an ordinary photo, but is radiometric.
Advantages of thermographic inspection
Thermographic inspection has now proved itself to be one of the most cost-saving techniques where solving temperature-technical problems is concerned (in the widest sense of the word). Thermographic inspection does of course have a number of clear advantages:
Inspection is carried out during operation, so there is no unnecessary production loss.
The measurement is contactless and takes little time.
Everything is recorded in a photo so there is clear evidence.
The inspection costs are relatively low.
