Infrared instrument detects hydrocarbon gases

Product Details Supplier Info More products

Crowcon’s IRmax is an ultra-compact infrared (IR) gas detector that delivers rapid, failsafe detection of hydrocarbon gases with very low power consumption.

Said to be 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 to 75C.

IRmax features Stay-Clir optical components that 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 reduced and the device requires only 1W of power – 75-90 per cent lower than conventional IR gas detectors, according to the company.

IRmax detectors require smaller and lower-cost power supplies and battery back-up systems.

In addition, low power consumption also means that longer cables can be used and more detectors can be powered on addressable networks.

A T90 response time of 4sec 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 feature of the IRmax is an optional IR Display, which can be fitted directly to the detector or mounted up to 30m 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.
