What is a Thermographic Inspection?

A Thermographic inspection makes use of specially designed infrared cameras to generate images that show surface heat variations. This technology has a number of applications.

Thermograms (the images captured by the thermal camera) of electrical systems can detect abnormally hot electrical connections or components. Thermograms of mechanical systems can detect the heat created by excessive friction.

Why use our Thermographic Inspection service?

Thermographic inspections are an investment in your business. Potential monetary savings from performing a yearly audit of your machinery can be worth as much as ten times as much as the cost of our service.

A thermal scanning and predictive maintenance service program performed by Lewis Bass evaluates the following common line items:

Electrical Panels

Circuit breakers



Motor-control Centers

Motor and generator connections, windings, feeders and exciters

Thermagrams taken from the above line items may detect hidden infrared hot spots that a member of the Lewis Bass team can interpret to determine and provide recommended mitigations.
