CO2H2SCI2NH3O3COO2CH4SO2CO2H2SFixed detectors for flammable, toxic or oxygen gasesXgard Type 1: Intrinsically safe toxic and oxygen gas detectorXgard Type 2: Flameproof toxic and oxygen gas detectorXgard Type 3: Flameproof flammable gas detectorXgard Type 4: Flameproof high temperature flammable gas detectorXgard Type 5: Flameproof flammable gas detector with 4-20mA outputXgard Type 6: Flameproof thermal conductivity type gas detectorXsafe: Safe area flammable gas detectorXgardXgardThe 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• Xgard detectors are designed for easy installation and maintenance to keep costs down.• The three junction box options are all designed to make replacement of sensors and sinters extremely simple.Spare sensors simply plug-in.• Many spare parts are common to all Xgard models, which keeps spares holding requirements to a minimum.Flexible installation options• Xgard is designed for either wall or ceiling mounting without the need for additional brackets.• Xgard can accommodate M20, 1/2” NPT or3/4” NPT cable glands to suit 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 for simple sensor checking.Wide range of sensorsXgard offers an extremely wide range of sensors for all applications:• 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• Xgard is 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. All versions are designed to operate even in the harshest conditions.• 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).Accessories(all accessories require an Accessory Adaptor to be fitted to the Xgard junction box)For outdoor use and protection against wash-down operations.Spray DeflectorFor use where a detector is installed in direct sunlightSun ShieldFor use in very wet conditions, such as offshore installations and ships.Weatherproof CapFor aiding detection of gases which are lighter than air, such as hydrogen and methane.Collector ConeFor use in sampling applications.Flow AdaptorFor fitting accessories to Xgard.Accessory AdaptorXgard labelAmplifier PCBUniversal junction box‘O’ ringPlug-in sensor moduleWall mounting lugsPCB coverScrew-on lidSensor retainer with sinter on flameproof modelsM20, 1/2” or 3/4” cable entryCeiling mounting lugsThe Xgard range offers a comprehensive selection of fixed point gas detectors that meet the diverse requirements for flammable and toxic gas detection and oxygen monitoring in industries throughout the world.This diagram is designed to help you choose the correct Xgard detector to suit your needs.Detector SelectorOrdering RequirementsThe following code is designed to help in the selection of the correct detector. The product reference number should be compiled by inserting the appropriate integer in each box.*1: Xgard Type 1 ATEX certified detectors will be supplied in a glass-reinforced nylon enclosure as standard, or in a 316 stainless steel enclosure as an option. Xgard Type 1 UL certified detectors and all other Xgard Types will be supplied in aluminium as standard, or in a 316 stainless steel enclosure as an option.*2: The stainless steel option is not available for Xsafe and Xgard type 4.
