The Latest Piece Of Test Equipment

• No More Guessing What Is Hot And What Is Not• Never burn your fingers again• Watch thermal events as they unfold• Thermocouples and Mercury bulbs are gone

the way of the Dodo bird• Permanent color images of tested

components• Test refrigeration / cooling systems too

This Is How It’s Done

Infrared Thermography:

• Infrared Imaging (Thermography) is not a new technology but now it is available to the mass public with better features, color interpolation and lower cost than ever before.

• There are low cost toys you can own and high priced feature packed models that are often more cost effective to rent with an operator who is skilled in testing and can give you a report.

What Can We Test:

• Motors, Transformers, Pump Bearings & Seals • Refrigeration Compressor Cases, Evaporator and

Condenser Coils• Relays, Terminals, Bolted Connections• Transmitter Stack Discharge Temperatures• Magnet Body Coils, Cavity Hot Spots, Filter

Heating, Water Flow Restrictions, Beam Supply Oil Levels, Water Tank Levels, Cabinet Finger Stock Heating, Tuning Component Heating

What Else Can We Test:

• Generator Engine Blocks and Alternators • Circuit Breakers and Panel Board connections• Ground and Neutral Heating• Wiring Troughs, Split Bolts and Wire Nuts• Heat Exchangers and Blower Motors• Coaxial Cable and Rigid Transmission Line• Coaxial and Waveguide Switches• Dummy and Reject Loads• Hybrid Couplers and Antennas

Likely Suspects ( Or Not )

More Likely Suspects ( Or Not )

Is It Hot? Not? Or Too Hot?• With Infrared Thermography you can differentiate

between objects that are close together where conventional hand held non-contact IR thermometers will not work.

• Detail heat signatures down to the component level is a valuable troubleshooting tool

• Thermal analysis of objects dozens to hundreds or thousands of feet away are now possible

Long Range Testing:

Long Range Lens

Normal Range Lens

Long Range Testing:

Antenna issues can be easy to “SEE” and can give an indication that more invasive Line Sweeping may be needed.

Notice the heating of the fiber rod metallic joint connections

Long Range Testing:

Night time images with on board illumination or ambient light give good results.

See how the temperature of the transmission line is easy to differentiate from the steel of the tower and lights.

Long Range Testing:

The long range Infrared Images are accompanied by a standard lens range color images for easy reference.

Images taken from over 2500 feet away

• Tremendous detail is available even with long lens applications.

• Dusk images show thermal loads on the steel and other components
