IR gas detector July 1st 2009 Crowcon's new IREX infrared (IR)
flammable gas detector is designed to
replace pellistor (catalytic bead) type
flammable gas detectors, resulting in
faster response times and reduced
zero drift. Capable of detecting
methane, butane, propane and many
other hydrocarbons, IREX is
specifically designed for the oil, gas
and petrochemical industries.
Pellistor and some other IR type
gas detectors are fitted with sinters
(flame arrestors) to achieve Exd
flameproof certification. Crowcon
says sinters slow response time and
can become blocked by
contaminants. Using an IREX
detector results in a T90 response
time of less than seven seconds,
comparable with the most expensive
conventional IR gas detectors. More articles from Crowcon Detection Instruments Ltd: |
