IR sensors
March 1st 2008 The Xgard IR from Crowcon is a
low cost infrared flammable gas
and carbon dioxide sensor
designed for use in fixed point
detection systems.
The company says conventional
flammable gas detectors based on
catalytic pellistors are susceptible
to poisoning in some industrial
atmospheres, making their
readings unreliable.
Crowcon says the Xgard IR is
totally immune to poisoning and
will reliably warn of gas hazards in
environments unsuitable for other
types of sensor. The sensor, a
simple plug-in module, will fail to
safety, detect flammable gas in inert
backgrounds and is not damaged
by high gas concentrations. More articles from Crowcon Detection Instruments Ltd: |
