Compressed Air Leak Detection System - FLEX.US Ultrasonic Leak Detector
|
The FLEX.US Ultrasonic Leak Detector kit comes with the FLEX.US Ultrasonic Leak Detector, carrying case and manual and uses two AA alkaline batteries (included). The FLEX.US Ultrasonic Leak Detector is a complete kit, the high quality flexible sensor is mounted on the end of a flexible steel pipe so the ultrasonic sound sensor can access hard to reach areas. The unit converts the ultrasonic noise of a leak into a sound humans can hear (hissing sound) not just some beeping sound or LED display that may not distinguish a leak sound from other phenomenon. The headset has excellent noise attenuation for use in the noisiest environments.
The FLEX.US Ultrasonic Leak Detector is a solid tool built to last, it is easy to use and will provide many years of service. FLEX.US Ultrasonic Leak Detector - How It Works Ultrasound is beyond the human hearing capacity. Most humans hear frequencies from 2 Hz to 20 kHz. Ultrasonic sound is beyond this range between 20 kHz to 100 kHz. The FLEX.US Ultrasonic Leak Detector converts the ultrasonic sound to an audible range for humans. Compressed air leaks generate this range of ultrasonic sound "noise" that the unit picks up.
Why The FLEX.US Ultrasonic Leak Detector Does The Job Remember The better the system, the more leaks you find and the more money you save. Always be aware of cheap ultrasonic leak detectors that just may not do the job. Ours does the job because of the following:
SECOND: Look at frequency range. Our frequency is centered at 38.4 kHz with an open window of +/- 2kHz. By having a bandwidth this narrow we are able to eliminate other sources of ultrasonic parasite noise. It is absolutely critical that you amplify just this narrow single harmonic band of sound. Some detectors amplify EVERY frequency from 20kHz up to 100kHz. That's because the manufacturer did not include any low pass filters. This also affects the output signal in the headphones. It also affects the directionality of the device. At low frequency it is much more difficult to know where the sound is coming from because the wavelength is larger and more reflective.

The
FLEX.US Ultrasonic
Leak Detector
is a hand held,
high quality
compressed air
leak detection
system that
has all the
features necessary
for flexible
use in finding
costly air leaks.
A
rugged carrying
case protects
the FLEX.US
Ultrasonic Leak
Detector when
not in use.
FIRST:
Look at the
headphones.
If they are
an open Walkman
style, it will
be useless in
a noisy plant
because they
offer absolutely
NO protection
from the ambient
noise which
can be at high
levels! (After
all, why else
would you need
an ultrasonic
lead detector!).
So how can you
hear the leak
in the headphone
without protection
from the ambient
audible noise
in the plant?
Our headphones
completely cover
the ear providing
130dB hearing
protection.
Some competitive
units would
not be useable
in a typical
factory where
hearing protection
is mandatory
because the
inspector would
have to insert
ear plugs in
his ears. Our
headphones don't
require this.
THIRD:
Extension tubes.
For accessing
tight areas some
firms suggest
using a hollow
tube (tubular
extension) with
their system.
Ultrasound will
not travel well
into this tube
so the equipment
will be less sensitive
in hard to reach
areas. If the
tube is 6"
long for example,
that means the
sensor is always
a minimum of 6"
away from the
source. The Nex
Flow system sensor
is at the end
of the flexible
extension so the
sensor is “always”
directly exposed
to the leak making
our equipment
much more sensitive.
If more sensitive
of course you
will more easily
detect the leak
(one you may not
even find it with
another system.)
