Thermography enables inspections to be done without actually coming into contact with the equipment that may be behind guarding or shields, significantly above or below ground level or otherwise inaccessible locations. The ability to determine structural damage, excessive heat buildup, the presence of water, without dismantling makes for cost effective inspection. A preventative maintenance program using thermal imaging to identify over heated bearings, bushings, couplers etc. can be identified and replaced with relatively inexpensive parts before damage to the expensive power source occurs. The frequency of inspections would be dependent on the risk factors and cost of a breakdown. If the inspection point is critical the location can be continuously monitored with the results transmitted to a remote monitoring station.
Infrared Thermal Imagine Non Destructive Testing (NDT) is based on the assumption that equipment which has a temperature above or below normal may be subject to failure.
The typical Thermal Imagine instrument has the capacity to store temperatures of the element of the equipment being examined in the range of –20 to 1200 degree Celsius in increments of .2 degree Celsius. To days temperature reading will be stored for comparison to previous or future readings. The trending reports will identify components that are progressively deteriorating from one examination to the next. Actual operating temperatures can be compared to the manufacturers specifications.
Infrared Thermal Imagine Non Destructive Testing (NDT) is not dependent upon visible “light” thus components of a machine not visible to the operator or maintenance staff can be recorded by the Infrared Thermal Instrument. There is no limit to the distance of the object from the Instrument. Obviously the closer the better. A preliminary examination of a motor / light fixture / breaker indicating an abnormality would warrant a much closer examination to determine the specific reason for the temperature variation .
Infrared Thermal Imaging will record a thermal image of the subject as well as a digital image. The images will enable the reader of the colour printed reports to more easily identify the areas of concern. The FLIR Reporter will highlight detected abnormalities
