INFRARED THERMOGRAPHIC ANALYSIS


Infrared thermography is the science of acquiring thermal radiation by electronic means and displaying the information as temperature contours on a monitor or video tape.


UNIVERSAL JOINT

Universal joint rotating at 1700 RPM.

The U-joint pins are lubricated

prior to operation. Analysis is to

test lubrication retention.

THERMOGRAM OF UNIVERSAL JOINT

Thermogram shows hot area

at U-joint pins indicating heating

and premature lubricant dry out,

a precursor of failure.

ELECTRICAL COIL

Large experimental electrical

coil for magnetic force measurement.

The device is being checked for

short circuits and

other faults.

THERMOGRAM OF COIL

Thermogram shows hot spots that

are short circuits which must be

repaired. The hot spots indicate

where to repair

the coil.

ELECTRICAL WIRING

Two electrical wires are

short circuited causing an arc.

As the arc continues, ionization

occurs.

ELECTRICAL ARC

Thermogram shows the ionized

cloud at the electrical

arc. The cloud is nearly

spherical.
