Ultrasonic gas detection system ensures earlier protection from combustible gas

05 August 2009

General Monitors now offers a fully integrated ultrasonic gas leak detection system that is suitable for a wide range of process safety monitoring applications. Ultrasonic gas leak detectors offer a responsive, reliable method for detecting gas that reduces the risk of fires and explosions.

The detectors respond to the ultrasonic noise generated by escaping gas at pressures of minimum 145 psi for maximum coverage of 5-20 m in radius. Ultrasonic technology detects gas leaks regardless of ventilation rates, gas dilution, or the direction of the leak – and without the gas having to make physical contact with a sensor element.

Gassonic detectors use a robust and accurate stainless steel microphone that measures the sound pressure level (SPL) in the ultrasonic range. T

hey feature the Senssonic integrated acoustic self-test, which periodically verifies the operation of the acoustic sensor to eliminate unrevealed failures. The detectors hold relevant C-UL and ATEX certifications. The Gassonic Observer is certified for SIL 2 and 3 systems, while the Gassonic Surveyor is suitable for SIL 1 and 2.
