It responds to the airborne ultrasound generated from gas releases in open, well-ventilated areas, where traditional methods of detection may be unsuitable or dependent on ventilation. Since the Gassonic Observer-H responds to the source of a gas release rather than the dispersed gas, it remains unaffected by changes in wind direction, gas dilution, and the direction of the gas leak. Further, with its wide coverage radius, it can supervise a relatively large area with a single device.
The Gassonic Observer-H is immune to many false signals and can be configured to filter short-timescale ultrasonic noise that can produce nuisance alarms. Frequencies below 25 kHz are removed by a high-pass filter, 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. The result is a reliable method of detection, capable of monitoring environments with high levels of ultrasound, such as turbine rooms and compressor stations.
The Gassonic Observer-H also features the Senssonic patented self-test for full failsafe operation. This self-test checks the electrical integrity of the device and microphone every 15 minutes, ensuring the Observer-H remains operational at all times. Additionally, the ultrasonic gas leak detector is available with Modbus or HART protocols to facilitate asset management and process improvement.
