Industrial Maintenance

Infrared thermography is a powerful & non-invasive method of monitoring and troubleshooting industrial processes and facilities.

When selecting a thermal imaging camera for industrial maintenance there are several considerations that should be taken into account. While a standard camera might provide excellent image quality, a harsh environment may present a whole new set of challenges.

Qualities to consider are:

environmental conditions for testing
temperature range
data gathering capabilities
ease of use
resolution

Environmental conditions or considerations include potential exposure to dust, dirt, water, chemicals and or extreme heat or cold. If the camera is not suited for the environment that it is used in, or not used with extreme care in harsh environments, its life could be very short lived. While you may be able to purchase a less expensive camera with similar radiometric specifications, cameras in this category are generally better suited for less than ideal testing conditions.

Temperature range should be carefully considered during the selection process. Lower temperature range cameras like those used in building science are not well suited for industrial applications where elevated temperatures and the need to quantify them exist. If the range selected is to low, high temperature objects will wash out in the image and over range the camera.

Data gathering is an important part of managing a thermography maintenance program. Because of PPE requirements in harsh or electrical environments, feature like voice annotation become very desirable when gloves make data recording hard if not impossible.

Ease of use is of critical importance when selecting an imager. Single handed operation, easy focus, hand straps, wrist straps, and other features which improve ergonomics are all features to consider.

Resolution is extremely important when your work is further away. Electrical inspection and mechanical inspection can provide may challenges when the distance becomes a limitation. Higher resolution means better image quality both near and far. While a higher resolution camera may initially cost more, the ability to work from the ground or at longer distances can improve workflow and eliminate the need for a lift.
