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, UL and GOST-R.

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^oc)
• 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)
