New Compact IRmax Infrared Hydrocarbon Gas Detector from Crowcon

Posted: Friday 24^th December 2010

Crowcon’s new IRmax is an ultra-compact infrared (IR) gas detector which delivers rapid, fail-safe detection of hydrocarbon gases with very low power consumption. Far smaller and lighter than comparable IR detectors, the IRmax is easy to install in even the most inaccessible locations.

Featuring dual-wavelength IR sensor technology in a rugged 316 stainless steel package, IRmax is designed to operate in the harshest conditions in temperatures ranging from -40°C to +75°C. Unlike conventional IR gas detectors, IRmax does not utilise heaters to prevent condensation on windows and mirrors – instead it has unique STAY-CLIR optical components which are treated with a highly durable coating that prevents faults due to condensation.

Because IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced – the device requires only 1 Watt of power, 75-90% lower than conventional IR gas detectors. IRmax detectors require smaller and lower cost power supplies and battery back-up systems. In addition, low power consumption also means longer cables can be used and more detectors can be powered on addressable networks.

A fast T90 response time of just four seconds is possible because of a compact diffusion gas chamber in combination with an effective weatherproof cap. The weatherproof cap also enables remote gassing and calibration of the detector without requiring a special calibration cap and without the need for scaffolding or cherry-pickers to access the detector.

Another important feature of the IRmax is an optional IR Display, which can be fitted directly to the detector or mounted up to 30 metres away to enable checking and calibration of detectors situated in remote or inaccessible areas. As well as delivering essential non-intrusive calibration functions, the display also provides diagnostic information and features to simplify testing and commissioning.

ATEX and IECEx certified for use in Zone 1 and Zone 2 hazardous areas, IRmax features HART communications and complies with the IEC61508 functional safety standard to SIL 2.
