In a bid to set a new global industry standard in highly reliable Ultrasonic gas leak detection, the MSA has introduced the new Gassonic Observer-I Ultrasonic Gas Leak Detector with Artificial Neural Network (ANN) intelligence.

MSA Africa Fixed Gas and Flame Detection product manager Robbie Taitz said in a statement recently that with the incorporation of ANN technology, the breakthrough Gassonic Obsever –I detectore is making it possible to fully analyse the sound spectrum above 12 kHz.

Taitz says the ANN algorithm has been trained to automatically distinguish between unwanted acoustic background noise and dangerous gas leaks.

He explains that the advanced ANN technology provides a broader leak detection range which also increases sensitivity to smaller gas leaks without interference from unwanted noise.

“It enables the Gassonic Obsever –I to be installed without time consuming training sequences and provides industry leading detection distance   with unprecedented suppression of false alarms, “he says.

The alarm is self adaptive therefore it requires no alarms set points to be configured nor do alarm set points need to be adjusted if background ultrasound were to increase or decrease over time, he says.

Taitz points out that Ultrasonic gas leak detectors are used in pressurized gas applications to complement conventional gas detection methods.

“In outdoor or ventilated locations, conventional detectors can miss gas leaks due to wind conditions, gas dilutions or leak directionality, “he says.

He says to compensate for such situations, ultrasonic gas leak detectors picks up gas leaks by responding to the airborne ultrasound instead of relying on physical contact between the gas and sensor element.

He further says the capability significantly improves total speed of response to dangerous gas leaks.

The Gassonic Observer-I features the patented Senssonic self test function which checks the devices electrical integrity and microphone every 15 minutes and ensures the detector is operational at all times.

He observes that that the Gassonic Observer-I is ideally suited for numerous applications ranging from offshore oil and gas platforms to refineries, underground gas storage facilities and downstream chemical processing plans.

He says the Gassonic Observer-I detector is designed to support larger plant distributed control systems and features Hart and Modbus communication compatibility along with 4-20mA output, providing complete status and control capability in the control room .

Taitz confirms that the Gassonic Observer –I detector features ATEX, IECEx, FM and CSA approvals and is SIL 3 suitable.
