Quick to respond
March 1st 2009 Crowcon's new IREX infrared (IR)
flammable gas detector is designed to
replace pellistor (catalytic bead) type
flammable gas detectors. It is said to
offer faster response times and
reduced zero drift.
Capable of detecting methane,
butane, propane and many other
hydrocarbons, it is designed for the
oil, gas and petrochemical industries.
Using an IREX detector results in
a T90 response time of less than 7s.
As IREX operates from the same
control systems as pellistor-based
detectors, it allows existing pellistorbased
systems to be easily upgraded
without the costs associated with
installing a new control system.
IREX produces a mV Wheatstone
Bridge type signal (identical to a
pellistor) and operates from as little
as 2VDC. It is supplied with an M20
type fixing, allowing originally
installed detector junction boxes and
cables to be retained. No adjustments
are needed to the detector itself. More articles from Crowcon Detection Instruments Ltd: |
