Ultrasonic Sound & Leak Detector
XLG-80 by Fisher Research
Pinpoints and amplifies sounds outside of human
hearing range
for detection of leaks, corona, and bearing wear.
 |
 |
 |
| Sensing
refrigerant leak in vehicle air conditioning. |
Sensing
pinhole air leaks in a pressurized telephone line. |
Sensing a
corona discharge at a transformer. |
Description
The XLG-80 detector was designed for industrial troubleshooting applications.
|
| 1.
|
Pressurized Telephone Cable. Leaks
from pressurized cable in the telephone industry are at such low
pressure they are outside of the human hearing range. The
combination of the transducer and control box of the XLG-80 converts
the sound so that it is unmistakable when the ultrasonic transducer
is pointed at or close to the source.
|
| 2.
|
Corona Discharge.
Prior to visible
arcing, there is an electrical discharge which sounds like
vigorously frying bacon when perceived by the XLG-80.
|
| 3.
|
Bearing Wear.
Long before vibration
sounds are apparent, changes in the volume of ultrasonic sounds are
an early indication of bearing failure. Steam Traps. The functioning
of a steam trap including "blow-bys", "machine
gunning", leakage, blockage, and oversized traps can all be
determined ultrasonically without interference from other nearby
sounds.
|
| 4.
|
Valves.
Closed valves which are seated
properly emit no sound. The slightest flow from a liquid or gas
valve can be detected ultrasonically.
|
| 5.
|
Gaseous Leaks.
Small air, nitrogen,
helium and other non-flammable and non-toxic gas leaks are easily
sensed with the XLG-80. Larger gaseous leaks are in the sonic range
and can be heard easily without instrumentation. Do not use the
XLG-80 for detecting flammable or toxic gas leaks.
|
| 6.
|
Water Leaks.
Water companies and
liquid leak detection professionals can make use of the XLG-80 when
they add air to a water system to cause a distinct
"sputtering" at the leak location. The sputtering and
whistle sounds are usually in the ultrasonic range.
|
| 7.
|
An optional transmitter can be used
with the XLG-90 or XLG-80 to sense weakened areas and pinholes in
tanks.
|
Features
|
| 1.
|
Inexpensive but complete kit for
ultrasonic sensing.
|
| 2.
|
Compact control box which can be worn
on the belt, around the neck, or over the shoulder with an
attachable strap.
|
| 3.
|
Minimum number of controls for a
user-friendly control panel.
|
| 4.
|
Listening is loudness limited to
lessen sudden blasts of uncomfortable sound.
