The Xgard Type 6 is an Exd Flameproof gas detector using a thermal conductivity sensor within an Xgard enclosure, which also contains an amplifier to provide a 3-wire 4-20mA sink or source output. Operating temperature +10 to +55°C. Designed to detect % vol. levels of gas in binary mixtures.

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.
