Crowcon Xgard Type 3 Fixed Gas Detector

The Crowcon Xgard Type 3 is an Exd Flameproof flammable gas detector using a poison-resistant pellistor within an Xgard enclosure, which also contains the terminals to provide a three-wire mV Wheatstone Bridge output. Can be connected directly to Crowcon Gasmaster and Gasmonitor. An Accessory Enclosure is required for connection to 4-20mA type control systems such as Vortex.

Suitable for use with a range of cable glands: M20 or 1/2″ NPT or 3/4″ NPT. There is a choice of housing: durable aluminium with a tough polyester coating or 316 stainless steel, suitable for deployment in extreme environments, such as offshore or in heavy industry, corrosion-resistant.

Units can be installed on walls or ceilings, with three junction box choices—replacement sensors plugin. Accessories are available for duct mounting, sampling applications and remote gassing – simple sensor checking. In wash-down areas or marine applications, splash guards and weatherproof caps are available.
