Gas detector DG-0E.CLO2/MR chlorine dioxide, nds/ndsch (cross-calibration), el-ch sensor

Gas detectors – reliable protection and control

Digital detectors of the DG/MR series, such as the DG-0E.CLO2/MR model, are devices designed for continuous monitoring of gas concentrations in various environments. These detectors measure the level of chlorine dioxide in the air, providing a quick response in case of exceeding permissible norms. In the event of an alarm, the detector signals this visually, changes the state of the relays, and sends information to the central supervisory module via the RS-485 network. This is crucial for ensuring safety in industrial plants, logistics centers, and public utility facilities.

Functionality and application

The DG-0E.CLO2/MR detector uses an electrochemical sensor for precise measurement of chlorine dioxide (ClO2) concentration. The replaceable sensor module facilitates maintenance, calibration, and reduces operating costs – sensor replacement is simple and does not require specialized knowledge. The device is compatible with the Digital Gas Detection System, allowing integration with existing monitoring infrastructure. Thanks to two alarm thresholds or measurement mode (for electrochemical sensors), the detector can be adapted to specific application needs.

Detectors from the DG/MR series find application in:

• industrial plants, where there is a risk of toxic gas emissions;
• logistics centers, requiring constant monitoring of air quality;
• public utility facilities, where safety is a priority;
• large rooms threatened by the emission of toxic or explosive gases.

Construction and user features

The DG-0E.CLO2/MR detector is characterized by a solid construction and easy installation. It has:

• RS-485 communication with MODBUS RTU protocol – enables integration with automation and control systems;
• two relays with NO/NC contacts – allow for activation of external alarms or ventilation systems;
• screwless terminals – facilitate connection of wires;
• two cable glands – allow connecting subsequent detectors in a network;
• configuration possibility using dedicated “DETnet View” software.

It is worth remembering that DG/MR detectors are not intended for use in explosion-hazardous areas. The devices are calibrated in their own GAZEX Accredited Calibration Laboratory according to PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees the accuracy and reliability of measurements. The detector is powered by 24V=. The dimensions of the device are 110 x 140 x 55 mm.
