Observer-i Ultrasonic Gas Leak Detector

Featured Product from MSA - The Safety Company


Designed with Artificial Neural Network (ANN) intelligence and real-time broadband acoustic sound processing technology, the state-of-the-art Observer-i Ultrasonic Gas Leak Detector sets a new global industry standard in highly reliable ultrasonic gas leak detection with unprecedented suppression of false alarms.

 With the incorporation of ANN technology, the breakthrough Observer-i Detector makes it possible to fully analyze the sound spectrum above 12 kHz. The ANN algorithm has been “trained” to automatically distinguish between unwanted acoustic background noise and dangerous gas leaks. This advanced design provides a broader leak detection range, which also increases sensitivity to smaller gas leaks without interference from unwanted background noise.

 ANN technology also enables the leading-edge Observer-i Detector to be installed without time consuming "training" sequences, and provides industry-leading detection distance (up to 30 meters). In addition, ANN technology ensures that the Observer-i Detector has the same gas leak detection coverage in high and low noise areas. Furthermore, because it is self-adaptive, the detector requires no alarm set points to be configured, nor do alarm set points need to be adjusted if background ultrasound were to increase or decrease over time.

 Ultrasonic gas leak detectors (UGLD) 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 dilution, or leak directionality. To compensate for such situations, ultrasonic gas leak detectors pick up gas leaks by responding to the airborne ultrasound instead of relying on physical contact between the gas and the sensor element. This capability significantly improves total speed of response to dangerous gas leaks.

 The Observer-i Detector features proven Gassonic ultrasonic technology including the patented Senssonic™ self-test function.  This well-proven self-test checks the device’s electrical integrity and microphone every 15 minutes and ensures the Observer-i Detector is operational at all times. Both the microphone and the microphone windscreen are constantly monitored to ensure that the detector always has optimal sensitivity and detection coverage.

 Designed to support large plant distributed control systems, the Observer-i Detector features HART and Modbus communication compatibility, along with 4-20 mA output, providing complete status and control capability in the control room. It features ATEX, IECEx, FM, DNV GL, MED, and CSA approvals and is SIL 3 suitable.
