Gassonic Launches Observer Ultrasonic Gas Detector

The Gassonic Observer Ultrasonic Gas Detector is a detector for fugitive gas leaks in compressor stations. It is a non-concentration based gas detector used to detect leaks from high-pressure systems. It responds to the airborne ultrasound generated from gas releases in open, well ventilated areas. Since the Gassonic Observer responds to the source of a gas release rather than the dispersed gas, it is unaffected by changing wind directions, gas dilution and the direction of the gas leak.

The Gassonic Observer is based on robust microphone technology and provides a detection radius of up to 20 meters at a leak rate of 0.1 kg/s. In addition, the detector offers the Senssonic integrated acoustic self-test, which periodically verifies the integrity of the electronic circuitry and the operation of the acoustic sensor. The detector features the following approvals: CSA, FM, ATEX, IECEx, and C-UL. The detector is SIL 2 suitable and is FM certified to IEC 61508.

The Gassonic Observer is designed with a high pass filter to remove frequencies below 25 kHz, effectively eliminating interference from audible and low frequency ultrasonic noise. At the same time, setting the alarm trigger level above the ultrasonic background noise ensures immunity to other noise sources.
