7.1 Leak search
With the WABCO Leakage Finder 2.0, leaks and untightness on compressed air components can be
located quickly and easily.
When a gas escapes from a leakage, the resulting turbulences - dependent on the pressure difference
and the size of the leakage - generate ultrasound. These ultrasonic signals are initially not perceptible
to the human ear. The WABCO Leakage Finder 2.0 converts the signals into visually and acoustically
perceptible information. The detectable tightness class is 10-2 mbar*l/s
