Xgard
The Xgard range of gas detectors has been specifically designed to meet
your requirements. The dangers presented by toxic and flammable gases
as well as oxygen deficiency vary with each application.
Xgard offers three different sensor concepts so you can choose exactly what you need for your site.
Xgard is available in flameproof, intrinsically safe or safe area formats for use in all environments,
whatever the classification.
Low cost of ownership
•
•
gard detectors are designed for easy installation and
X
maintenance to keep costs down.
T he three junction box options are all designed to make
replacement of sensors and sinters extremely simple.
Spare sensors simply plug-in.
• Many spare parts are common to all Xgard models, which
Wide range of sensors
Xgard offers an extremely wide range of sensors for all
applications:
•
•
keeps spares holding requirements to a minimum.
•
P
oison 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.
Flexible installation options
Rugged and reliable
•
•
•
•
•
Xgard is designed for either wall or ceiling mounting
without the need for additional brackets.
Xgard can accommodate M20, 1/2” NPT or
3
/4” NPT cable glands to suit 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 for simple sensor
checking.
•
Xgard is 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. All
versions are designed to operate even in the harshest
conditions.
Spray deflectors and weatherproof caps are available
for use in areas subject to regular wash-downs, or
offshore environments.
A
ll models have been validated to the functional
safety standard IEC 61508 (SIL 1 to SIL 3).
