Gas detector DG-1R2/N methane, 10/30% LEL, IR sensor

Gas Detectors – Reliable Safety in Any Environment

The DG-1R2/N gas detector is an advanced device designed for continuous monitoring of methane presence in the air. It utilizes an infrared (IR) sensor, ensuring high precision and reliability of measurements in the range of 10% to 30% of the Lower Explosive Limit (LEL). This detector is suitable for both industrial installations and residential buildings where gas leakage risk exists.

Construction and Operating Principle

The DG-1R2/N detector is part of the DG/F series, characterized by a modular design. This means that the sensor module can be easily replaced if necessary, significantly reducing service and calibration costs. The device uses infrared absorption measurement technology, which allows for selective detection of methane even in the presence of other gases. Built-in optical indicators inform about the detector's operating status and exceeding the set alarm thresholds.

Detectors from the DG/F series are designed to work with various control modules, such as MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8 and MDP-16. Please note that these detectors have a standard construction and cannot be used in areas with a risk of explosion of gases, vapors or dust.

Key Features and Benefits

• High Selectivity: The IR sensor provides a precise measurement of methane concentration, minimizing the risk of false alarms.
• Modular Design: Allows for quick and easy replacement of the sensor module in case of failure or the need for calibration.
• Optical Signaling: Built-in LEDs indicate the detector's operating status and exceeding alarm thresholds.
• Wide Measurement Range: The detector operates in the range of concentrations from 10% to 30% LEL, allowing its use in various conditions.
• Calibration: All GAZEX detectors are calibrated in their own Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees the accuracy and reliability of measurements.
• Simple Installation: Modularity and no need for calibration at the installation site facilitate and speed up the installation of the device.
• Splash-proof Housing: Provides protection against moisture and mechanical damage (IP44).

Applications

The DG-1R2/N detector is ideal for the following situations:

• Monitoring methane concentration in gas installations.
• Detecting gas leaks in industrial and commercial premises.
• Protecting residential buildings against the risk of gas poisoning.
• Fire alarm and signaling systems.
• Atmosphere control in confined spaces (e.g., tanks, ventilation ducts).

The device is particularly recommended for gas system installers and companies servicing heating and ventilation equipment due to its ease of installation and configuration, as well as low operating costs. For end-users, it provides a guarantee of safety and comfort when using the building or installation.
