Gas Detectors DEX/A – Reliable Protection Against Hazards

Gas detectors of the DEX/A series are devices designed for continuous monitoring of dangerous gas or vapor concentrations in enclosed spaces. They signal exceeding two alarm thresholds, ensuring a quick response in emergency situations. An explosion-proof design allows their use in potentially hazardous areas. The DEX-A14/N detector, equipped with a selective methane sensor, is particularly recommended for industrial applications and boiler rooms where precise detection of this gas is required.

Features and Application

The DEX-A14/N detector uses a semiconductor sensor to detect methane in the range of 10-30% LEL (Lower Explosive Limit). A4-C construction with an aluminum housing ensures durability and corrosion resistance. The device operates with a 3-wire 4-20mA interface, enabling easy integration with control and alarm systems. Thanks to the ATEX certificate, the detector meets stringent safety standards and can be used in explosion-hazardous areas.

These detectors find applications in many areas, including:

• Industry: monitoring gas leaks in production plants, refineries, gas installations.
• Boiler rooms: controlling methane concentration in rooms with heating devices.
• Wastewater treatment plants and biogas plants: detecting methane generated during fermentation processes.
• Confined spaces: ensuring safety in warehouses, underground garages and other rooms with limited air access.

Advantages of the DEX-A14/N Detector

• High selectivity: the sensor reacts primarily to methane, minimizing the risk of false alarms caused by other gases.
• Wide measurement range: 10-30% LEL allows for the detection of both small leaks and high gas concentrations.
• Durable construction: the aluminum housing protects the device from mechanical damage and external factors.
• ATEX certificate: guarantee of safety and compliance with applicable standards.
• Easy integration: 4-20mA interface allows connection to various control and alarm systems.
• Reliability: thanks to the use of high-quality components, the detector ensures long-lasting and trouble-free operation.
• Versatility: compatibility with various control modules (MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16; MDD-1, MDD-1/T, MDD-1x/T; MD-1) and central units accepting a 4-20mA signal (after using a power limiter MDPL1).

The DEX-A14/N detector is an investment in safety – reliable methane detection protects people and property from potential hazards related to explosion or gas poisoning.
