Methane detector DG-14/MR-Nstd – reliable protection against explosion and poisoning

The DG-14/MR-Nstd gas detector is an advanced device designed for continuous monitoring of methane concentration in the air. It uses a selective semiconductor sensor, providing precise measurements and minimizing the risk of false alarms. The device is a key element of gas detection systems, protecting both people and installations from potential hazards.

Construction and principle of operation

The DG-14/MR-Nstd detector is based on proven gas semiconductor sensor technology. A built-in microprocessor ensures stable and reliable operation, and a thermal compensation circuit minimizes the impact of temperature changes on measurement accuracy. If defined alarm thresholds are exceeded, the detector signals the hazard optically and by changing the state of the built-in relays. Alarm information can also be transmitted to a central supervisory module via RS-485 communication with the MODBUS RTU protocol. A replaceable sensor module facilitates maintenance and calibration, reducing operating costs.

Application in practice

The DG-14/MR-Nstd detector finds wide application in places where there is a risk of methane leakage, such as:

• Industrial plants: monitoring methane concentration in production and storage areas.
• Logistics centers: safety control in warehouses of gases and flammable materials.
• Public utility facilities: protection against gas explosion in residential, commercial and public buildings.
• Large rooms: protection against the accumulation of methane in production halls, boiler rooms and other large spaces.

Thanks to its design and functionality, this detector is ideal for both professional installers of gas detection systems and end-users who care about safety in their surroundings. Semi-automatic addressing in a digital network facilitates integration with existing monitoring systems. Two cable glands allow easy connection of subsequent detectors in a network.

Key product features:

• High selectivity: The sensor reacts primarily to methane, minimizing the risk of false alarms caused by other gases.
• RS-485 communication: Enables integration with building management and control systems (BMS).
• Two alarm thresholds: Allow flexible adaptation to specific working conditions and safety requirements.
• Replaceable sensor module: Facilitates maintenance, calibration and reduces operating costs.
• Solid construction: Ensures durability and reliable operation even in harsh industrial conditions.
• Software configuration: The detector can be easily configured using the dedicated "DETnet View" software.
• Calibration in own laboratory: All detectors are calibrated in their own GAZEX Calibration Laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation no. AP150).
