Description

The analog cGas Detector is designed for use in non-explosion rated, commercial / light industrial applications that require continuous monitoring of carbon dioxide or alcohols such as ethanol or methanol.

It offers one 4-20 mA analog output, is powered by 24 VDC or ground referenced AC and has an LCD display, temperature compensation and a thermal resetting fuse. The firmware and configuration can be upgraded in the field using a USB connection. Pre-calibrated sensors with true Plug & Play Smart Sensor technology makes replacing sensors quick and easy.

The cGas Detector comes in a standard water / dust tight, corrosion resistant ABS/ polycarbonate enclosure with a hinged, secured door. With the optional, factory installed splash guard the enclosure is IP54 rated and provides protection in water spray or wash down applications.

Note: Ethanol and Methanol are highly flammable. The cGas Detector is intended for use in non-classified areas only. Follow project specifications. If monitoring area is classified, our combustible or infrared CXT Explosion Proof products would be a suitable alternative.
