Ultrasonic Gas Leak Detectors – Observer-I Get latest price

Principle of Operation

The GASSONIC OBSERVER-i makes it possible to fully analyse 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 GASSONIC 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 GASSONIC 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.
