6.1.1
Functional description
The WABCO Leakage Finder 2.0 is used to detect ultrasonic signals.
Using WABCO Leakage Finder 2.0, faulty components can be located in systems and their risk
potential for the process evaluated. Ultrasonic signals, e.g. caused by friction on damaged parts, form
the basis. Ultrasound can occur in a variety of processes, including:
on leaks in compressed air, steam and vacuum systems
when operating steam traps
on leaking valves, gate valves, shutoff valves or cocks in pipe systems
during the operation of roller bearings
in the case of cavitation caused by pumps and compressors
The ultrasonic signals generated during the above processes are recorded with the WABCO Leakage
Finder 2.0, converted into audible sound and output in their intensity via headphones or a loudspeaker.
At the same time, the level of the ultrasound is shown graphically on a display.
The sound pressure is given in dB (relative value). This is calculated from the ratio of the sound
pressure to the reference value of the microphone voltage of 1 μV.
The following applies: 1 μV
≙
0 dBμV
If the measured value is less than 1 μV, negative dB values may also occur. Values below 0 dB are at
the detection limit of the instrument and are unsuitable for reliable evaluations.
