Ultrasonic Gas Leak Detector

Principles of Ultrasonic Gas Leak Detection

Ultrasonic gas leak detection uses acoustic sensors to identify fluctuations in noise that is imperceptible to human hearing within a process environment. The sensor and electronics are able to detect these ultrasound frequencies (25 to 100KHz), while excluding audible frequencies (0 to 25KHz). Unlike traditional gas detectors that measure the accumulated gas, ultrasonic gas detectors “hear” the leak, triggering an early warning system.
