Methane detector DEX-14/N-S methane, 10/30% LEL, F4-S-C p-p sensor, stainless steel housing, for wastewater treatment plants

Methane detector DEX-14/N-S – reliable protection against explosion and poisoning

The DEX-14/N-S methane detector is an advanced device designed for continuous monitoring of methane concentration in enclosed spaces. Designed with safety in mind in demanding conditions, it finds application both in wastewater treatment plants and biogas plants, as well as in other industrial facilities where there is a risk of explosion or gas poisoning. The device signals exceeding two alarm thresholds, ensuring a quick response in the event of a hazard.

Construction and application

The DEX-14/N-S detector is characterized by a solid construction based on a stainless steel housing, which guarantees high resistance to corrosion and mechanical damage. F4-S-C execution and the use of a semiconductor sensor (p-p) make the detector particularly effective in monitoring methane concentration in environments with increased humidity and aggressive chemicals. The device is designed to cooperate with various GAZEX 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), providing flexibility and the possibility of integration with existing alarm systems.

Key features and benefits

• High selectivity: The detector has been designed to precisely detect methane (CH₄), minimizing the risk of false alarms caused by the presence of other gases.
• Durable construction: The stainless steel housing provides resistance to corrosion and mechanical damage, extending the life of the device even in harsh industrial conditions.
• ATEX compliance: The detector meets the requirements of Directive 2014/34/UE (ATEX), guaranteeing safe use in areas at risk of explosion of gases or flammable vapors (II 2G).
• Two-stage alarm: Signaling the exceeding of two alarm thresholds (A1 and A2) allows for a quick response and minimization of the risk of serious consequences.
• Replaceable sensor: The ability to replace the sensor module allows for easy calibration and maintenance of the device and reduces operating costs.
• Intended for wastewater treatment plants: A special F4-S-C execution dedicated to applications in wastewater treatment plants and biogas plants ensures reliable operation in specific environmental conditions.
• Measurement range: The detector operates in the range of 10/30% LEL (Lower Explosive Limit), which corresponds to typical methane concentrations occurring in industrial installations.
• Calibration: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150).

The DEX-14/N-S detector is an investment in safety and reliability of explosive gas monitoring – for both professional installers and end users.
