Crowcon Xgard (Type 4) High Temperature Flammable Gas Detector (Methane 0-100% LEL)
The Xgard range is a comprehensive selection of fixed point gas detectors that meet the diverse requirements for gas detection in industries throughout the world. This includes many water treatment, oil and gas, power, research facility and manufacturing installations. 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, GOST-R and MED.
Type 4 Exd Flameproof flammable gas detectors use a poison resistant pellistor within a 316 stainless steel housing attached to an Xgard enclosure (aluminium), which also contains the terminals to provide a 3-wire mV Wheatsone Bridge output. Operating temperature -20 to +150?C. Can be connected directly to Crowcon Gasmaster and Gasmonitor, an Accessory Enclosure accessory is required for connection to 4-20mA type control systems such as Vortex.
Key Features:
Designed for easy installation and maintenance – keeps costs down Detector designed to detect Methane 0-100% LEL Many spare parts are common to all Xgard models – keeps spares holding requirements to a minimum 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 Poison resistant pellistors, for all flammable detection needs including hydrocarbons, hydrogen, ammonia, jet fuel, leaded petrol and vapours containing halogens 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)
