Xgard (Please call for price)

Overview
Intrinsically Safe (I.S.) or Flameproof (Exd) versions are available, with case options comprising high-grade alloy, stainless steel or chemically resistant GRN polymer. Certifications include IECEx, ATEX and UL.
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
  • The Xgard multi gas detectors are 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 150oc)
  • 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)
