| Where compressed air escapes, friction develops between the gas molecules and the pipe wall. This friction produces a high-frequency ultrasound inaudible to the human ear. The LEAK DETECTOR registers the ultrasound, transforms it into an audible sound and indicates it optically. In this respect, only those frequencies are registered which will occur in the case of leakage. Thus, the precise location of the leak is also identified where the industrial noise is present. Using the LEAK DETECTOR, the detection of compressed air losses at microcracks, worn-out flange joints, defective sealing rings or loosened connections no longer presents a problem. |
