Leak testing by ultrasonic-bubble-detection

To detect leaks of production parts, under water visual testing can be used. If using this cost-effective method in an automatized way, ultrasonic-bubble-detection can be easily used and integrated. First of all, apply pressure to the test object and then dive it into the water bath. If there is detected a leak, air bubbles rise.  The bubbles can be detected and localised by the so called ultrasonic-bubble-detection-system. This method can be used and applied for fuel tanks, heat exchangers and pipings as well as hydraulic cyclinders.
