Gassonic Observer-I Ultrasonic Gas Leak Detector
Acoustic Gas Leak Detection (AGLD)The OBSERVER-i is the world’s first ultrasonic gas leak detector equipped with Artificial Neural Network (ANN) real-time broadband acoustic sound processing technology. This technology is based on extensive studies and real recording of gas leak sounds and industrial background noise from a wide array of industry sources over the years. The ANN algorithm has been “trained” with these recordings to automatically distinguish between unwanted acoustic background noise and dangerous gas leaks.
Description
With ANN technology, the OBSERVER-i makes it possible to fully analyze the sound spectrum as low as 12 kHz since common high pass filters are not used. This provides a broader leak detection range which also increases sensitivity to smaller gas leaks, without interference from unwanted background noise. ANN technology enables the OBSERVER-i to be installed without time consuming “training” sequences, and provides industry-leading detection distance, with unprecedented suppression of false alarms. In addition, ANN technology ensures that the OBSERVER-i has the same gas leak detection coverage in high and low noise areas.
The device requires no alarm set points or trigger levels to be configured, nor do these alarm parameters need to be adjusted if background ultrasound were to increase or decrease over time. The OBSERVER-i is backwards compatible with earlier versions of the Observer by means of the Classic Mode setting wherein ANN is disabled and the legacy electrical interface is used. The OBSERVER-i features the patented Senssonic™ self-test function.
This well-proven self-test checks the device’s electrical integrity and microphone every 15 minutes and ensures the OBSERVER-i is operational at all times. The microphone and the microphone windscreen are constantly monitored to ensure that the detector always has optimal sensitivity and detection coverage.
