Xgard Type 2 Flameproof Toxic and Oxygen Detector by Crowcon

The Xgard range of gas detectors has been specifically designed to meet your requirements. The dangers presented by toxic and flammable gases as well as oxygen deficiency vary with each application.

Xgard offers three different sensor concepts so you can choose exactly what you need for your site. Xgard is available in flameproof, intrinsically safe, or safe area formats for use in all environments, whatever the classification.

Low cost of ownership

  • Designed for easy installation and maintenance - keeps costs down
  • Three junction box options - designed to make replacement of sensors and sinters extremely simple. Spare sensors simply plug-in
  • Many spare parts are common to all Xgard models - keeps spares holding requirements to a minimum

Flexible installation options

  • Designed for either wall or ceiling mounting - no need for additional brackets
  • Can accommodate M20, 1/2" NPT or 3/4" NPT cable glands - suits all site requirements
  • High temperature models are available for hot environments (up to 150°c)
  • Accessories are available for duct mounting and sampling applications as well as remote gassing - simple sensor checking

Wide range of sensors

  • Poison resistant pellistors, for all flammable detection needs including hydrocarbons, hydrogen, ammonia, jet fuel, leaded petrol and vapours containing halogens
  • Electrochemical sensors are used to detect a vast range of toxic gases and oxygen
  • Thermal conductivity sensors are available to monitor % volume concentrations of gases

Rugged and reliable

  • Manufactured using a choice of three materials: glass reinforced nylon, highly durable aluminium with a tough polyester coating, or 316 stainless steel for ultimate corrosion resistance - designed to operate even in the harshest environments
  • Spray deflectors and weatherproof caps are available for use in areas subject to regular wash-downs, or offshore environments
  • All models have been validated to the functional safety standard IEC 61508 (SIL 1 to SIL 3)
