Polytron 8900 UGLD

December 7, 2020 | Product News

Polytron 8900 UGLD

The Polytron 8900 UGLD contains an ultrasonic sensor that detects gas leaks regardless of environmental influences, even before a gas detection sensor detects a critical concentration.

The Polytron 8900 UGLD improves safety and efficiency and has a flexible installation with intrinsically safe remote sensor casing with cable also available. The sensor lifespan is 10+ years, which means no sensor replacement in the meantime. The results are easy to interpret as they are shown in percentages and the durable design and fully sealed sensor for reliable use even in harsh conditions.

An HSE study came to the conclusion that 36% of major gas releases and 69% of significant gas releases (0.1 – 1.0 kg/s) are undetected by gas detectors.

“Field trials have indicated that gas plumes in well ventilated areas may not be detected by fixed point or open path detectors. Analysis of hydrocarbon release incidents shows that conventional gas detectors have 65% detection efficiency.”

In the event of a potentially hazardous situation, the measured sound pressure is displayed in an easy-to-understand test value range of 0 to 100% (equivalent to 55 – 110 dBA). This value is easy to interpret, giving you complete transparency over the task at hand.

The Polytron 8900 UGLD triggers the gas leak alarm whenever the ultrasound caused by the gas leak exceeds background noise by 11% for a pre-adjustable period of up to 30 seconds.

The DrägerSensor® UGLD Ultrasonic Sensor

This unique sensor is PVC coated ceramic piezo, which does not need weather guard. The sensor has a built-in self-test, which runs hourly. A co-centric ring design inner ring reverses polarity to become speaker. The sensor has calibration memory, built-in temperature sensor, and an intrinsically safe design that is field replaceable without declassifying area.

Models and Accessories

Polytron 8900 UGLD (Ultrasonic Gas Leak Detector) and Polytron 8900 UGLD (Ultrasonic Gas Leak Detector with Remote Sensor)

Calibration Kit – for regular functionality checks

Field Survey Device – pre-installation background noise analysis

Commissioning Test Device – enables you to create leak simulations of up to 100 g/sec

Draeger Polysoft Software – facilitates configuration and readout of the Polytron 8900 UGLD

Schneider Electric Pressure Transmitter and the NSI OPA

November 4, 2020 | Product News

Need a flowmeter using differential pressure and an orifice plate, but don’t find it easy doing all of the necessary calculations and parts assembly?  Earlier this year we released our “OPA” product line, which featured a Foxboro IDP50S DP transmitter, a Lambda Square Orifice plate, and all of the necessary engineering know-how and parts to provide a total solution.  One recent customer just placed their second order, since they valued the fact that we could provide them all of the necessary process details and engineering for one turn-key solution.   

In case you missed it, here’s the video from our Technical Lead John Lamp, explaining the OPA series.  In addition, Foxboro just released a new video on the transmitter we chose! Here is their latest video showing why this Pressure Transmitter Series from Schneider Electric is the most unique on the market!
