IR flammable gas detector is ATEX approved
01 October 2008
Crowcon’s IREX infrared flammable gas detector is designed to replace pellistor type flammable gas detectors, resulting in faster response times of less than seven seconds and greatly reduced zero drift.
Capable of detecting methane, butane, propane and many other hydrocarbons.
IREX operates from the same control systems as pellistor-based detectors, so it allows existing pellistor-based systems to be easily upgraded without any of the costs associated with installing a new control system. IREX produces a mV Wheatstone Bridge type signal and operates from as little as 2Vdc. It is
supplied with a M20 type fixing, allowing originally installed detector junction boxes and cables to be retained.
Zero and span adjustments, if required, are performed at the control panel, and gas response tests and calibration can also be done remotely, with test gas is simply applied via a tube to the standard weather cover.
IREX is designed to provide over 10 years reliable operation, and operating costs during its entire lifetime are minimal. Manufactured from 316 stainless steel, IREX has both ATEX and IECEx approval and is undergoing assessment for IEC61508 SIL 2 compliance.
