INFRARED THERMOGRAPHY

AND VIBRATION

MONITORING

What is in f rared thermography.? ?

Infrared thermography is equipment or method, which detects infrared energy emitted from object, converts it to temperature, and displays image of temperature distribution.

HISTORY OF IRT.!

PRINCIPLES OF INFRARED THERMOGRAPHY

•THERMAL IMAGING.

•THERMOGRAMS

• heat and temperature.

• > conduction•> convection•> radiation
