Compressed Air Ultrasonic Leak Detector L300
Compressed air is one of the most expensive energy forms. 15% to 20% of this could easily be saved as a large portion of these costs are caused by leaks in compressed air systems. The air “escapes” unused.
The Ultrasonic leak detector L300 allows maintenance personnel to detect a leak on the spot by being able to distinguish the leak sound among various equipment sounds.
Applications include leak detection for,
- Compressed air systems
- Tanks
- Pneumatic brakes
- Pipe systems
- Oxygen plugs in hospitals
- Pressure and vacuum systems
- Steam traps
- Valves
- Refrigerants
- Partial electrical discharges causing damages on insulations
- Insulation tests on doors and windows
- Tightness tests
- Any gas leaks in general
When gases are leaking through tubes and tanks an ultrasonic sound is produced which can be detected by L300 even from several meters distance. L300 transforms these inaudible signals into a frequency which can be easily heard by using the supplied noise isolated headset. In unpressurized systems an ultrasonic tone generator can be used whose sound will leak through small openings. The ability to discriminate between these sounds is accomplished by an electronic process called ‘heterodyning’ that accurately converts the inaudible ultrasounds sensed by the instrument into the audible range where users can hear the audible signal through supplied noise isolated headset. It is therefore simple to isolate these signals from any background plant noises and to detect their exact location. The high frequency, short wave, directional characteristic of ultrasound enables users to accurately pinpoint the location of a leak or a particular sound in a machine. The basic advantages of ultrasonic instruments are that they can easily locate leaks, provide advanced warning of impending mechanical failure and can be used in loud, noisy environments. In unpressurized systems an ultrasonic tone generator can be used whose sound will leak through small openings. The L300 integrates a laser pointer which helps to spot the leak from distance.
Optional Accessories
Ultrasonic Tone Generator
The optional ultrasonic tone generator can be a useful addition to the standard kit for detection of leaks from unpressurised pipes, vessels, enclosures, and tightness tests. This allows for testing of welds, joints and seals without the cost or contamination issues of actual gas testing. The ultrasonic tone generator can also be useful as a training tool for new users.
