How the Thermal Imager Works and Thermal Imaging Buyers Guide

Thermal Imaging - Here's how it works:

A special lens focuses the infrared light emitted by all of the objects in view.
The focused light is scanned by a phased array of infrared-detector elements. The detector elements create a very detailed temperature pattern called a thermogram. It only takes about one-thirtieth of a second for the detector array to obtain the temperature information to make the thermogram. This information is obtained from several thousand points in the field of view of the detector array. 

The thermogram created by the detector elements is translated into electric impulses.
The impulses are sent to a signal-processing unit, a circuit board with a dedicated chip that translates the information from the elements into data for the display.
The signal-processing unit sends the information to the display, where it appears as various colors depending on the intensity of the infrared emission. The combination of all the impulses from all of the elements creates the image. 

How the Wahl Thermal Imager Works
Thermal Imaging is a technique for creating an image of a scene based on the invisible thermal radiation emitted from an object. Using this technology, thermal images of faults in mechanical or electrical plant can be displayed.

Thermal imaging can be used in any process where the temperature of the object gives an indication of its state not visible to the eye. For example, a loose electrical connection or a worn bearing will heat up. These defects can be seen with a thermal imager as a 'hot spot'.

The ability to measure the temperature of an overheating component enables the operator to determine the seriousness of the fault, and take corrective action before costly breakdown occurs.

How to Purchase a Thermal Imaging Camera
