Gas detector DG-3R/N organic compounds, 20/40% LEL, IR sensor

Gas detector – reliable safety in industry

The DG-3R/N gas detector is an advanced device designed to detect leaks of organic gases in industrial and enclosed spaces. It utilizes an infrared (IR) sensor, which ensures high precision and reliability of measurements in the range of 20-40% LEL. This detector is a key element of safety systems, protecting against hazards related to the presence of explosive or toxic substances.

Construction and application

The DG-3R/N detector, thanks to its replaceable sensor module, is extremely flexible and easy to adapt to different needs. The ability to replace the module not only facilitates calibration and repairs but also allows changing the detector model without replacing the entire device. This is particularly important in the case of changing working conditions or the need to monitor other gases. The device works 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, which enables integration with existing alarm and control systems.

It is important to remember that the detectors of the DG/F series have a standard construction and cannot be used in areas at risk of explosion of gases, vapors or dusts – this is an important limitation when planning installations.

Advantages and benefits

• High measurement accuracy: The IR sensor ensures accurate detection of organic gases over a wide range of concentrations (20-40% LEL).
• Easy maintenance: The replaceable sensor module significantly reduces calibration and repair costs and allows for quick change of the detector model.
• Versatility: Compatibility with various control modules facilitates integration with existing safety systems.
• Optical signaling: Built-in optical signaling informs about the detector's operating status and exceeding alarm thresholds.
• Splash-proof housing: The housing made of high-impact ABS (IP44) protects the device against moisture and mechanical damage (with the recommended mounting position).
• Calibration: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation no. AP150), which guarantees their accuracy and reliability of measurements.
• Modularity: Simple construction and no need for calibration at the installation site significantly speed up the system installation and commissioning process.
• Resistance to temporary concentration spikes: The sensor is resistant to short-term increases in gas concentration, which minimizes the risk of false alarms.

The DG-3R/N detector is an investment in safety and comfort of work in demanding industrial environments. Its reliability, precision and ease of use make it an ideal choice for both professional installers and end-users who care about protecting the health and life of employees.
