IRT — Infrared Thermography

A non-contact inspection technique that detects and visualizes temperature variations using infrared imaging technology.

Definition

Infrared Thermography (IRT) is a nondestructive testing and condition monitoring technique that uses infrared cameras to measure and visualize surface temperature distributions. Thermal images identify abnormal heat patterns associated with electrical faults, insulation failures, refractory damage, mechanical defects, fluid leakage and process abnormalities without interrupting equipment operation.

Why It Matters

Infrared Thermography enables early detection of developing equipment problems by identifying abnormal thermal signatures before failures occur.

In Practice

IRT inspections are widely used within predictive maintenance programs because they can identify overheating components and deteriorating equipment without requiring physical contact or process shutdown.

Common Misuse

Infrared Thermography detects temperature differences remotely, whereas Ultrasonic Testing evaluates internal material conditions using high-frequency sound waves.
