Low cost of ownership
- Designed for easy installation and maintenance – keeps costs down
- Three junction box options – designed to make replacement of sensors and sinters extremely simple. Spare sensors simply plug-in
- Many spare parts are common to all Xgard models – keeps spares holding requirements to a minimum
Flexible installation options
- 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
- Electrochemical sensors are used to detect a vast range of toxic gases and oxygen
- Thermal conductivity sensors are available to monitor % volume concentrations of gases
Rugged and reliable
- 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)
