General Monitors has introduced a new Gassonic Observer-H Ultrasonic Gas Leak Detector for a range of applications.

A General Monitors press release describes the product as being ideal for compressor stations, hydrogen storage, LNG, and refineries, among a number of other applications.

The Gassonic Observer-H is ideal for gas leak detection in pressurised systems and features HART communications, Modbus with single and block transfer modes, Emerson AMS Intelligent Device Manager support, and event logging.

The Observer-H is ATEX, IECEx, FM and CSA hazardous area certified and SIL 3 suitable.

The new product detects gas leaks by sensing the airborne ultrasound emitted from leaking gas at high pressure. It is suitable for gas detection in open, well-ventilated areas, where traditional detection methods may be unsuitable or dependent on ventilation.

Since the gas leak detector 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 leak. The Gassonic Observer-H’s wide coverage zone makes it possible to supervise areas up to a 20 meter radius, for the detection of leaks as small as 0.1 kg/sec., with only one device.

Rugged and designed for failsafe operation, the Gassonic Observer-H features robust microphone technology with an advanced stainlesssteel microphone. The detector also offers the Senssonic™ integrated acoustic self-test, which verifies the integrity of the instrument’s electric circuit and microphone every 15 minutes. It features stainless steel, AISI 316L explosion-proof housing, offering corrosion resistance in the harshest environments.
