Sensor detects co2 October 1st 2007 The Xgard IR from Crowcon
is a new, low cost infrared
(IR) flammable gas and
carbon dioxide sensor for
use in fixed point detection
systems.
The company says that
conventional
flammable gas
detectors based on
catalytic pellistors
are susceptible to
poisonoing in some
industrial
atmospheres. This
can make their
readings unreliable
and even destroy
the sensor
altogether. The
Xgard IR is said to
be totally immune
to poisoning.
The IR sensors will fail to
safety, detect flammable gas
in inert backgrounds and
are not damaged by high
gas concentrations.
The device can be
specified with two types of
enclosure: polyester-coated
aluminium or 316 stainless
steel for corrosion
resistance in extreme
environments. The sensor is
a simple plug-in module.
ATEX and IEXEx approved,
Xgard IR is Exd flameproof
rated. More articles from Crowcon Detection Instruments Ltd: |
