Dräger releases the Polytron 8900 ultrasonic gas leak detector

The Dräger Polytron 8900 ultrasonic gas leak detector (UGLD) transmitter is an early warning area monitor for detecting high-pressure gas leaks in outdoor industrial process environments.  

Thanks to an ultrasonic acoustic sensor, it responds earlier than conventional gas detectors because it registers the sound of leaking gas, instead of measuring the concentration of accumulated gas clouds. As gas escapes, leaks are immediately detected in the surrounding area, regardless of the wind direction. 

Gases that are discharged from compressed gas lines or containers, at more than 29 pounds per square inch, generate both audible and inaudible noises. Industrial noises primarily occur in the audible spectrum. Polytron 8900 measures in the inaudible ultrasonic range and can, therefore, detect methane gas leaks of 3.5 ounces per second within a radius of approximately 49 feet, even in loud industrial environments.  

“The Polytron 8900 UGLD is not affected by environmental influences, such as wind or by background noise, and detects a gas leak on a compressed gas line as soon as the gas escapes,” explained John Wilson, Dräger’s senior vice president of marketing and sales for safety solutions in North America. “An early warning system for leaking gas can prevent a plant, or part of a plant, from having to be shut down unnecessarily, thus saving time and money.” 

Polytron 8900 UGLD is designed for use in Class I Div I hazardous areas and certified as SIL 2 by TÜV. It is resistant to water and dirt and has an expected life span of more than 10 years.
