Gas detectors – reliable safety in industry

The DG-0E.SO2/N gas detector is a device designed for continuous monitoring of sulfur dioxide (SO2) concentration in the air. It finds application in industrial and enclosed spaces where there is a risk of dangerous concentrations of this gas. Equipped with an electrochemical sensor, the detector provides precise measurement and signaling when defined alarm thresholds are exceeded. This is crucial for protecting the health of employees and ensuring safe working conditions.

Construction and principle of operation

The DG-0E.SO2/N detector belongs to the DG/F series, characterized by an exchangeable sensor module with two programmable alarm thresholds. The detector's construction is "conventional", which means it cannot be used in areas at risk of explosion from gases, vapors or dust – this is an important consideration when planning installation. The exchangeable sensor module design greatly simplifies calibration and repairs, and also allows changing the type of detected gas without having to replace the entire device. This reduces operating and servicing costs.

Applications and benefits

• SO2 detection: A specialized electrochemical sensor provides precise measurement of sulfur dioxide concentration, which is important in many industrial processes.
• Two-stage alarm signaling: Enables quick response to gas concentration increase and minimizes the risk of exposure to harmful substances.
• Easy maintenance: Exchangeable sensor module simplifies calibration and repairs, reducing installation downtime.
• Modularity: Compatibility 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) provides flexibility of the gas monitoring system.
• Calibration: Detectors are calibrated in their own GAZEX Accredited Calibration Laboratory according to PN-EN ISO/IEC 17025 (PCA No. AP150), which guarantees measurement accuracy.
• Splash-proof housing: Provides protection against moisture and mechanical damage (IP44).
• Optical signaling: Built-in optical signaling informs about the detector's operating status and exceeding alarm thresholds.

The DG-0E.SO2/N detector is a reliable tool for installers of gas monitoring systems and end-users looking for an effective solution to protect against hazards related to the presence of sulfur dioxide in the air. Its simple operation and high measurement accuracy make it an ideal choice for a wide range of industrial applications.
