FEATURES

The Marksman II Ultrasonic Diagnostic Tool converts and amplifies
inaudible ultrasonic sound into audible "natural" sound by
employing technologically advanced circuitry. It operates on the
principle of detecting high frequency ultrasonic waves, which are
created by friction from all moving parts, whether solid, liquid or
gaseous. These "sounds" reside far above the range of the human
ear and tend to be highly directional.
This directional aspect of ultrasonic waves allows one to isolate a
suspect signature sound from other background noises and detect its
exact location. This sound analysis can be used for efficiently
investigating the following areas of repair and preventive maintenance
in the following transportation and industrial applications:
1. Air leaks
Both vacuum and compressed air leaks create an energy packet or
wave front which can result in an ultrasonic emission with a
differential of 5 psi from a 12 inch (30.5 cm) distance, and/or a hole
down to 0.004 inches (0.1 mm) in diameter.
2. A/C refrigerant leaks (for most types of refrigerant)
3. Gas and liquid turbulence
Turbulence associated with steam trap and internal valve leaks,
cavitation, and blockages in liquid and air/gas lines.
4. Electrical discharge
Electrical discharge associated with insulation breakdown,
tracking, corona and arcing.
5. Diagnosing solenoid operations
6. Mechanical wear
State of mechanical wear in bearing and race assemblies, shafts
and gears (also indicating the state of lubrication).
INTRODUCTION
Faults, malfunctions and/or flaws in mechanical, electrical and
pneumatic devices, as well as in container-type objects, start as
small defects or leaks. The physical size of these defects is so
