Gas detector DEX-A31/N organic vapors, 20/40% LEL, A4-B design, p-p sensor, brass housing

Gas detectors – reliable safety in any environment

The DEX-A31/N gas detector is an advanced device designed for continuous monitoring of dangerous concentrations of organic gases in the air. Equipped with a semiconductor sensor, the detector signals exceeding two alarm thresholds (20/40% LEL), ensuring a quick response in case of a hazard. Explosion-proof design and a solid brass housing guarantee reliable operation even in harsh industrial conditions.

Application and functionality

The DEX-A31/N detector finds wide application in various industrial facilities, such as:

• Chemical industry: monitoring leaks of solvents and other organic substances.
• Refineries and petrochemical plants: control of gas concentrations in production processes.
• Automotive workshops and paint shops: protection against harmful fumes.
• Warehouses and storage facilities: detection of dangerous gas concentrations during the storage of chemicals.
• Boilers and furnaces: control of gas emissions during fuel combustion.

The device works with various control modules, such as MDP-1, MDP-4, MDD-1, allowing integration with existing alarm and control systems. The 4-20mA output allows easy connection to a central unit accepting standard input lines with current emission.

Design and product features

The DEX-A31/N detector is characterized by a solid explosion-proof design, which ensures safe operation in areas threatened by the explosion of gases or flammable vapors (IIA, IIB, IIC). The brass housing provides high resistance to corrosion and mechanical damage. A4-B execution guarantees appropriate durability and reliability of the device. The semiconductor sensor provides high sensitivity and selectivity in measuring organic compounds. Compact dimensions (105 x 103 x 54 mm) facilitate installation in hard-to-reach places. The device meets the requirements of the ATEX Directive, confirming its compliance with European safety standards.
