Natural gas detector methane, 10/30% DGW, AL housing, F4-C design, p-p sensor, for gas boiler rooms DEX-12/N

Natural Gas (Methane) Detector DEX-12/N – Safety for Your Home and Business

The natural gas detector DEX-12/N is a reliable device designed for continuous monitoring of methane presence in the air. Designed to provide maximum safety, this detector is an ideal solution for both installers and end-users, especially in gas boiler rooms and other rooms where gas leaks may potentially occur. The device signals exceeding two alarm thresholds, ensuring a quick response in case of danger.

Features and Application

The DEX-12/N detector is made with an aluminum (AL) housing and features F4-C construction with a semiconductor sensor (p-p). The explosion-proof design of the device allows its use in areas at risk of explosion of gases or flammable vapors (IIA, IIB, IIC), making it an indispensable element of safety systems in industrial and public utility facilities. Thanks to this, the detector not only protects against the direct threat of explosion but also minimizes the risk of carbon monoxide poisoning resulting from incomplete gas combustion.

The device is compatible with various control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, MDD-1, MDD-1/T, MDD-1x/T), enabling integration with existing alarm and access control systems. The detector meets the requirements of ATEX Directive 2014/34/UE and the Regulation of the Minister of Development of June 6, 2016, confirming its compliance with the highest safety standards.

Advantages of the DEX-12/N Detector

• High sensitivity: The semiconductor sensor provides precise methane detection even at low concentrations.
• Wide measurement range: The detector operates in the range of 10/30% LEL (Lower Explosive Limit), allowing monitoring of different hazard levels.
• Durable construction: The aluminum housing provides resistance to mechanical damage and corrosion.
• ATEX compliance: Guarantee of safe use in potentially explosive atmospheres.
• Easy integration: Compatibility with various control modules simplifies installation and configuration of the alarm system.
• Replaceable sensor: Allows quick replacement of a damaged sensor without replacing the entire device – reduces operating costs.
• Calibration: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), ensuring measurement accuracy.
• Intended for gas boiler rooms: Ideally suited to the specific conditions prevailing in gas boiler rooms.

Technical Data (for professionals)

The DEX-12/N detector is powered by an external system and has two bistable (threshold) outputs. The dimensions of the device are 105 x 103 x 54 mm. The device is designed to operate at a temperature of -10°C to +40°C (recommended) and -20°C to +45°C (periodically permissible). Avoid contact of the sensor with silicone substances and strong reducing compounds during operation of the detector to ensure its long-term efficiency.
