설명
This product is no longer available.
Ultrasonic sound (20 to 100 kHz) is
generated by turbulence created by air
or a gas forced through a small orifice.
Ultrasonic sound is very directional in
nature and can be used to pinpoint the
exact location of the leak point. Leaking
air or gas is generally considered
to be viscous flow and as the flow
velocity increases, the frequency of the
ultrasonic sound emitted will become
higher. The HHLT-1R amplifies and
converts these sounds to frequencies
and levels that the human ear can hear.
The HHLT-1T transmitter can supply
ultrasonic signals for locations where
the gas/air leak does not have sufficient
pressure to create an ultrasonic sound.
This transmitter will allow the ultrasonic
detection of cracks and openings.
Detection Principle
When a gas passes through a restricted
orifice under pressure, it’s going from a
pressurized laminar flow to low pressure
turbulent flow. The turbulence generates
a broad spectrum of sound called “white
noise”. There are ultrasonic components
in this white noise. Since the ultrasound
will be loudest by the leak site, the
detection of these signals is usually
quite simple.
