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.
