Crowcon Xgard (Type 5) Flameproof Flammable Gas Detector with 4-20mA Output
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 5 Exd Flameproof flammable gas detectors use a poison resistant pellistor within an Xgard enclosure, which also contains an amplifier to provide a 3-wire 4-20mA output. Operating temperature -40 to +55?C. Xgard Type 5 units are designed from a sturdy aluminium material as standard.
