Description

The Crowcon Xgard Type 1 (XG1) is an intrinsically safe fixed-point detector for toxic gases and oxygen. Its electrochemical sensor runs on a 2-wire 4-20mA loop, and the sensor range is the widest in the Xgard family — from hydrogen sulfide, carbon monoxide and ammonia to arsine, bromine, hydrogen fluoride and volatile organics — plus a long-life oxygen sensor with a 2-year lifespan that halves sensor replacement cost versus conventional oxygen detectors.

Fitted in a Zone 0, 1 or 2 (Class I, Division 1) area, it operates through a zener barrier or galvanic isolator. The UL/cUL configurations listed here are supplied in aluminium or 316 stainless steel junction boxes.

How to read the configuration code: each code spells out the build — XG type, then housing and cable entry (A = aluminium, S = 316 stainless steel, N = glass-reinforced (GRP) nylon; 1 = M20, 2 = 1/2" NPT, 4 = 3/4" NPT, 5 = 2× M20), certification (01 = ATEX/IECEx, 02 = UL/cUL, 07 = INMETRO), then the gas code. Every configuration in the dropdown also names its housing, thread, gas, range and certification in full.

Certifications on this page: configurations are listed in UL/cUL, ATEX/IECEx and INMETRO builds. The certification of each configuration is stated in full at the end of its dropdown label — check it before ordering, as certifications are not interchangeable and an ATEX/IECEx or INMETRO build is not a UL/cUL unit.

Common Applications:
Oil & Gas • Petrochemical • Chemical Plants • Water & Wastewater • Steel • Power Generation • Marine & Offshore

  • Intrinsically safe (Ex ia) for Zone 0, 1 or 2 and Class I, Division 1 areas — barrier or galvanic isolator required
  • Electrochemical sensors for toxic gases and oxygen, 2-wire 4-20mA (current sink) output
  • Long-life oxygen sensor with a 2-year lifespan
  • Universal Xgard junction box — sensors and sinters are plug-in, so replacement takes minutes
  • Wall or ceiling mounting with no additional brackets
  • Many spare parts are common to all Xgard models, keeping spares holding to a minimum
  • Junction boxes in polyester-coated aluminium or 316 stainless steel (UL builds)
  • Accessories available for duct mounting, sampling and remote gassing
  • Spray deflectors and weatherproof caps available for washdown and offshore environments
