Infrared exproof detectors for explosive gases & CO2


DIREX X is the new detector using infrared technology for explosives and CO2 gas detection.

It has been designed for its use in environments with probability of formation of an explosive atmosphere because of vapours or gases. (Group II of instruments - Category 2 from the ATEX Directive)

It is certified meeting the European Standard ATEX LOM08ATEX2059 X

DIREX X has been specially designed for:

Installations with presence of inhibitant or poisonous gases for catalytic detectors – pellistors. DIREX X is not affected by these gases.

Available gases; pentane, ethane, ethylene oxide, propilene, natural gas, propane, butane methane and carbon dioxide.

In atmospheres with no oxygen presence.Unlike pellistors, DIREX X does not need oxygen for its functioning.

For CO2 infrared detection, contrary to other technologies, CO2 presence does not reduce sensor's useful life. DIREX X is not affected by CO2 presence.

At those installations with special conditions where maintenance operations must be reduced to the minimum. DIREX X only requires to be checked once every 3 years.

Also available in RS485C format.

Detection range from 0 to 100% L.E.L. (explosives) & from 0 to 2% vol. (CO2)

Optical indications for sensor and loop faults.

Optional programmable relay output module: 1 programmable alarm level, instant/retarded disconnection, retard disconnection programming and initial relay idle state.

Reusable adaptor, which considerably reduces maintenance costs.

Calibrated at factory with target gas: no need to calibrate them at installation.
