Reactive maintenance and repair costs due to equipment failure can be quite aggravating and costly for companies. Thermal imaging can play an important role in enabling maintenance professionals to monitor equipment performance and therefore schedule planned maintenance while also extending the lifespan of essential machinery and equipment.

What is Thermal Imaging?

Heat generation is often an early indication of equipment failure or damage, making it vital to monitor. Thermal imaging uses infrared-sensitive cameras to inspect the infrared energy emitted by electrical equipment, machinery or buildings and produce thermal or heat pictures to help maintenance technicians locate faults commonly related to heat loss or heat gain. Thermal imaging cameras can measure and compare heat signatures for equipment and machinery without interrupting operations which allows maintenance technicians to instantly verify thermal performance of buildings or industrial equipment. 

Thermal imaging is often the first inspection tool a maintenance technician will use as part of their preventive maintenance program. Inspections take less time than repairs. Therefore, using thermal imaging on a regular basis to monitor the temperature of essential equipment makes it possible to track operating conditions over time and swiftly identify irregular readings. This will help maintenance personnel to determine a course of action where required.

Benefits of Thermal Imaging

Key benefits of thermal imaging include:

Thermal Imaging Applications

Until recently thermal imaging cameras were prohibitively expensive. In more recent years, technology has improved and pricing has been brought down to a level which is more affordable, in turn, opening up a host of new applications. 

Examples of Thermal Imaging Applications include:

Inspection Process

  1. Review maintenance history and compile a list of equipment for maintenance survey. Do not include equipment that is not suitable for infrared measurement. Prioritize key equipment that is problematic or prone to failure.
  2. Use a database to group critical equipment together. This may be determined either by area or function. Allow 2 to 3 hours per inspection block. 
  3. Use thermal imaging camera to capture baseline images of each piece of equipment.
  4. Record both numeric temperatures and thermal images to facilitate long-term data analysis. Temperature trends will help guide you as to which equipment required further investigation and which equipment may require less frequent inspection.
  5. Download the baseline images and temperatures and document your report with location information, inspection notes, alarm levels where appropriate and any other data relevant to your inspection.
  6. Once you have a database of baseline images, allocate an alarm temperature to each one. 
  7. Prior to the next inspection, and where your camera allows, upload the previous thermal images on to the camera. If the alarm goes off when you take the new measurement, it indicates a significant change in temperature that will require further investigation.
  8. Following the same steps each time you carry out an inspection ensures that you have consistent thermal images in your database for comparison.
