Page 3: Theory Of Ultrasonic Leakage Detection
1. THEORY OF ULTRASONIC GAS LEAKAGE DETECTION Human ear can hear sound frequency up to 18 KHz. The sound frequency above 20 KHz is categorized as ultrasonic sound which is not audible. Ultrasonic sound is very directional in nature. We can utilize this nature to pinpoint the exact origin of the sound source where the leak is located. -

(7) Electrical arcing. Electrical arcing can be detected with the ultrasonic leakage detector. Arcing produces a rich ultrasonic spectrum that is quite noisy. Used the PVC pipe accessory to extend the sensor horn of the dector for safety purpose. (8) To check the bearing problems. (9) Bake system. -
