Key Thermal Imaging Applications

2022. jan. 13.

Everything on the planet produces infrared radiation, or heat. We cannot perceive it with the naked eye, but it can be detected with thermal imaging cameras. This modern technology is now used in almost every industry.

Thermal cameras can troubleshoot and analyze working machinery, pinpoint heat loss in building construction and improve security systems by revealing the unseen through detection of infrared radiation. These cameras are a powerful way for contractors and other technicians to save time and money, and prevent accidents that could lead to loss of property and life.


What Is Thermal Imaging?

Thermal imaging equipment does not see through objects, like an X-ray camera, but rather detects varying levels of heat based on the infrared waves emitted by the objects. Professional thermal imaging cameras can see subtle differences in temperature to create a detailed image of hot and cold areas with accurate temperature measurements. Differences in temperature can be used to pinpoint potential problems in malfunctioning equipment and in systems that have been installed improperly.

What Industries Use Thermal Imaging for Maintenance?

The benefit is that thermal scans do not require equipment to be shut down to be inspected.  The trained operator can quickly inspect and document faults and determine when repairs should be scheduled.

Safety is another reason that thermal cameras have become a regular tool for maintenance teams. Technicians do not have to be close to the machinery being tested as the photo can be taken from a distance, keeping techs safe while still acquiring the needed information.

Industrial Maintenance

Manufacturing companies often operate 24 hours a day, and taking equipment off-line to run any type of maintenance can cost businesses extremely valuable time. Reliability is enhanced when thermal imaging is part of an asset inspection and condition-based maintenance program (CBM). Downtime and maintenance expenses can both be reduced with a CBM program since maintenance only occurs when it's needed, rather than on a set schedule. Thermal imaging allows excessive heat in electrical, mechanical, and process equipment to be detected early in the failure curve. This minimizes the risk of a catastrophic failure, business interruption, and potentially dangerous conditions.

Utility Work

Electrical distribution systems support millions of users every day, and locating potential failures in the lines and in the metering is essential for providing constant service to customers. Transformers, circuit breakers, switches and bushings are common points in the system that will heat up before failure.  Thermal cameras can detect the hotspots, measure the temperature, and allow reliability engineers to schedule repairs.

Home Inspections

Home inspectors must find problems that are seen and unseen. One of the major concerns in a home inspection is finding water leaks that have not revealed themselves. Determining if there is excessive moisture and finding the source of a leak through the normal inspection process may prove impossible. Wet building materials will tend to be colder than dry materials and a thermal camera can alert an inspector where there may be problems. Wet insulation, framing, and drywall can be revealed, allowing potential home buyers to make an informed decision and a good investment.

Home Building

Thermal imaging is also used for air leaks (air tightness), Indoor Air quality, humidity and thermal bridging. Using a thermal camera during the build will ensure quality, reduce rework and costly callbacks.


It is also common for plumbers  to use thermal cameras to diagnose problems with floor heating systems.  A thermal camera can mean the difference between removing one tile to fix the problem and tearing out an expensive tile floor.

Thermal Imaging Equipment as Handheld Tools for Preventive Maintenance

The best maintenance practices require the ability to assess problems within minutes. Broken machinery, out-of-service electrical grids and homes that leak energy are issues that do not have to be a surprise. While early thermal cameras were bulky, complex and expensive, today's cameras are compact, rugged, affordable and can fit on a contractor's tool belt. But just because a thermal camera is portable doesn't mean the data it provides is limited. Professional equipment provides excellent image clarity, the ability to shoot stills and video with a high frame rate, multiple lens options and affordability.

Regardless of the industry you are involved in, thermal imaging should be an integral part of your company’s success plan.

How to Best Use Thermal Imaging Cameras for Home Inspections
Fact: A home inspection is a valuable service that can provide key insight into the systems a homeowner relies on. As a home inspector, you can provide an even more elevated quality of inspection and reporting by using a thermal camera to perform home inspections. Thermal imaging gathers data that can be interpreted by trained professionals to provide robust energy and systems reports.
Using Thermal Cameras To Find Electrical Faults
As most electricians know, heat is the byproduct of an operating electrical circuit. Excessive heat is also a way for service technicians to identify any hot spots and potentially dangerous electrical faults. These faults can increase costs through equipment failure, additional repairs, and service interruptions for business or related facilities.

An electrical fault is an abnormal condition that alters voltage or current. For example, it can be a loose connection, damaged insulation, or a buildup of debris. Because current flow naturally generates heat, faults can create thermal hazards which cause property damage and interrupt normal operations.
