Step by step guide to using the CABIN-SAFE™ for hole detection –
- The CABIN-SAFE™ transmitter is placed inside the container, vessel or vehicle. The magnetic base can be used to hold the transmitter in a convenient place. The unit should be switched on, and the green LED should flash.
- The headphones are plugged into the SLD receiver. The trigger turns on the SLD (Sonic Leak Detector) and the laser will shine out of the tube. The tube is often referred to as the nose. It is there to direct the sound into the internal microphone.
- The surveyor begins to inspect the vessel or vehicle, moving the SLD across the exterior of the vessel. Any gaps through which air or water can pass will allow the ultrasonic signal to pass and can be detected.
- Any ultrasound that can escape to the outside is converted to an audible sound that can be heard through the headphones. The louder the sound, the larger the leak.
Step by step guide to using the CABIN-SAFE™ for gas detection –
The SLD (Sonic Leak Detector) when used on its own allows the rapid detection of pressurised gases escaping from any form of plant system.
The ultrasound ‘noise’ generated from any gas, e.g. – compressed air, steam, refrigerant or vacuum, bad bearings and electrical arcing can be easily detected, and the leak location can be rapidly and accurately identified through the headphones.
The SLD can significantly reduce leak detection times and produce substantial cost savings.
Savings potential in compressed air plants –
In many companies, compressed air systems have leaks in the ducts, coupling and hoses (leakages of 30% and more are not uncommon).
This results in significant costs for the company. Moreover, this results in additional unnecessary maintenance measures are required for the compressor and the compressed air processing.
The following example clearly shows the financial consequences of smaller leaks, (which are acoustically hardly perceivable by the human ear). Average operating costs for compressed air costing 0.02EUR/m³ at 7 bar; per year, see chart below –
