• Evaluate equipment reliably, efficiently, and without disruption to operations.
• Ensure uninterrupted power.
• Avoid costly failures and shutdowns.
• Postpone previously scheduled maintenance of equipment found to be in good condition.
• Verify new equipment installations to establish a baseline for future inspections.

In many cases, the savings in insurance claims due to predicted equipment failure have pushed insurance companies to obligate their clients to perform regular infrared inspections as a term of their policy renewal.
Many studies have shown that the financial and safety benefits to industrial and commercial facilities far outweigh the costs of implementing and maintaining an effective PdM program.
What is Infrared Thermography?
Heat is referred to as the transfer of electromagnetic energy, in the infrared band, through either conduction, convection, or radiation between two or more substances. The measurement of the transfer of this infrared energy is called temperature. There is no heat or temperature without this energy transfer. Infrared energy is invisible to the human eye but can be felt , sensed, and measured.
What is Infrared What is Infrared Thermography?Thermography?
The infrared camera evaluates and converts heat energy into meaningful temperatures. Components in various states of failure will emit more heat as a direct result of more energy dissipated into the component.
This extra energy is caused by increased friction in mechanical devices, and higher resistance in electrical devices.
What is Infrared What is Infrared Thermography?Thermography?
Why Use Infrared Thermography?
Just as doctors use temperature in disease diagnosis, infrared thermography allows us to diagnose and pinpoint problems based on the temperature differential of areas. Temperature provides an excellent indication of the condition of equipment.
It is the ability of the thermal camera to "see" these early stages of increasing temperature that makes thermography such a valuable technology.
