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
relatively small that the sounds they produce are above the range
of human hearing. Most commonly, these faults generate sounds
in the 38,000 to 43,000 cycles per second range, generally referred
to as being in the ultrasonic range.

To employ the ultrasound methodology in a usable manner, it is
imperative that the listener have access to an audible sound that
bears a resemblance to the natural sound of the defect.
A mechanical bearing with a defective ball should sound like such.

Likewise, converting the ultrasound frequencies to audible
frequencies is not sufficient with regard to rendering a usable
signal. For this reason, the Marksman II incorporates a
process whereby the audible signal bears a close likeness to
the natural incoming sample. We call this process “Sound

Signature Technology,” whereby a gas leak sounds like a gas leak
and a defective bearing sounds like one.

GENERAL INFORMATION

The Marksman II is sensitive only to ultrasound (40.5 kHz) and is
unaffected by audible noise. Internal Noise Control (I.N.C.) allows
the use of this instrument in extremely noisy environments such as
mechanical rooms, around operational chillers, etc. Drag your
finger upwards on the sensitivity touch pad to increase sensitivity
when experiencing little or no environmental noise. Drag your
finger downwards on the sensitivity touch pad to reduce sensitivity
in response to an increase in environmental noise. The I.N.C.
works much like a two-way radio squelch allowing only the
strongest and closest signals to penetrate the electronic wall built
by the I.N.C. circuitry.

Many variables can affect the amount of ultrasound generated by
the leakage of gas through an orifice. Such factors include the
pressure/vacuum versus the surrounding environment, how smooth
the edges of the orifice are, the diameter of the orifice, the leak
detector’s distance from the orifice and the presence of airflow,
which may dissipate the ultrasound. As you use the Marksman II,
keep in mind that these factors may affect your ability to detect
ultrasonic leaks.

KIT CONFIGURATIONS AND COMPONENTS

TP-9367 Master Kit Contains

1. The Marksman II ultrasonic receiver. This easy-to-use unit
incorporates audio feedback and five LEDs to indicate the
intensity of the signal. The receiver has a permanently fixed
2-inch directional receiver port, 3.5 mm stereo jack port,
sensitivity adjustment pad and power button.

2. One black rubber 7
length contact probe.

3. A full-sized headphone set with a 3.5 mm stereo jack.

4. A rugged carrying case for storage and transportation.

5. The ultrasonic emitter. Sends out a 40kHz pulse for use in
testing seal integrity in non-pressurized vessels.

6. Two “D” cell alkaline batteries.

Ultrasonic Emitter

The emitter gives off a warble output centered at 40kHz. This
output cannot be heard by the human ear. If the red indicator is on,
the unit is emitting.
