The Crowcon Xgard Type 1 is an Exia Intrinsically Safe toxic and oxygen gas detector using an electrochemical sensor within an Xgard enclosure, which also contains the amplifier/transmitter to provide a two-wire 4 to 20mA sink output. A Zener barrier or galvanic isolator is required for I.S. hazardous area operation.

Suitable for use with a range of cable glands; M20 or 1/2″ NPT or 3/4″ NPT. There is a choice of housing; glass-reinforced nylon, durable aluminium with a tough polyester coating, or 316 stainless steel suitable for deployment in extreme environments, such as offshore or in heavy industry- corrosion resistant.

Units can be installed on walls or ceilings, with three junction box choices—replacement sensors plugin.  Accessories are available for duct mounting, sampling applications and remote gassing – simple sensor checking.  In wash down areas or marine applications, splash guards and weatherproof caps are available.

Features

  • Simple install and maintenance, common spares for all Xgard types, minimise inventory
  • Validated to IEC 61508 (SIL 1 to SIL 3)
  • Ingress protection IP65
  • Operating temperature -40 to +50°C (range varies for some sensor types)
  • Response time T90 <15s Oxygen. T90 <30s to 120s Toxic
  • Global approvals ATEX/ IECEx UL, INMETRO & GOST-R
  • Size 156 x 166 x 111 mm (6.1 x 6.5 x 4.3 inches)
  • Weight Nylon 0.5kg, Aluminium 1kg & Stainless Steel 3.1kg
