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)
