Ultrasound works by detecting the high frequency sound associated with friction, arcing and turbulence in industrial systems. These sounds are translated/converted down to the audible range where they can be heard in the headset and viewed on the meter. Translation is done by heterodyning --comparing the incoming signal with one generated by the meter. Our meters are most sensitive to sounds around 40 kHz, that's twice the frequency of the best human hearing. Because we focus on a specific band of sound... wind noise, industrial noises, voices, traffic, and most normal operational sounds will NOT be detected. You can actually yell directly into the sensor and hear nothing. This exact frequency focus allows for precise leak detection and bearing defect discovery.
