allsun Ultrasonic Leak Detector Diagnostic Stethoscope 36-44kHz Air/Contact Probe,Kit w/Rotary Volume,Tone Generator,Find Vacuum Gas Seal Faults,Auto& Industrial Leak Detection Tool
This tool consists of an ultrasound receiver, a tone generator, an air probe, a contact probe and a headphone.
The receiver is sensitive only to ultrasonic energy in the frequency range of 36000 to 44000Hz. The energy is amplified by internal circuitry and converted to audible sounds (available through the headphone) and an intensity reading on the red LED display.
The tone generator is used with the ultrasound receiver to check for faulty seals in nonpressurized enclosures, such as automotive cabin windows/doors/roofs, etc.
Operating Principle
Moving parts, liquids and gases cause turbulence or friction.This turbulence or friction can produces high frequency ultrasonic waves whose frequencies are normally higher than 20kHz and are far above the range of human hearing.
This Ultrasonic Diagnostic Tool operates on the principle mentioned above, it uses advanced ultrasonic sensing technology and converts inaudible ultrasonic sound into an audible sound which bears a close likeness to the natural incoming sample.
