What is an Ultrasonic Gas Leak Detector?
Basically, ultrasonic gas leak detector is also known as UGLD and is a non-centrifugal base detector. It detects ultrasound generated by pressurized gas escaping from leak points. Ultrasound is a pulse signal in the air, which is detected by the human ear through a microphone. The UGLD is designed to ignore audible noise and perceive low ultrasonic frequencies and only ultrasonic frequencies in the range of 25 kHz to 70 kHz. UGLD measures ultrasonic sound in decibels (dB). When a gas leak occurs within the range of the detector, the sound level will exceed the trigger level of the UGLD and generate an alarm.
Conventional gas concentration base detectors become problematic in open ventilated areas where the gas is easily diluted and the gas moves away from the sensor. UGLD solves this problem by detecting the acoustic ultrasound produced by pressurized gas escaping from the leak.
