Gas detector DG-0E.O3/MR ozone, 0.2/0.3 ppm, electrochemical sensor

Ozone gas detector DG-0E.O3/MR – reliable air quality monitoring

The DG-0E.O3/MR gas detector is an advanced device designed for continuous monitoring of ozone concentration in premises. It uses an electrochemical sensor, providing a precise measurement in the range of 0.2 – 0.3 ppm. This makes it suitable for both industrial plants, logistics centers, and public utility facilities, where air quality control is crucial.

Functionality and application

The device is part of the GAZEX Digital Gas Detection System, enabling integration with other detectors and a central supervisory module via an RS-485 interface with the MODBUS RTU protocol. In the event of exceeding defined alarm thresholds, the detector signals this with a built-in optical signaling and activates two low-voltage relays (NO/NC contacts). This allows for a quick response and minimization of the risk associated with the presence of harmful substances.

The DG-0E.O3/MR detector finds application everywhere where monitoring of ozone concentration is required:

• Industrial plants: control of processes generating ozone or exposed to its action.
• Logistics centers: monitoring of air quality in warehouses and loading areas.
• Public utility facilities: ensuring safe conditions for users of buildings (e.g., swimming pools with ozone water treatment).
• Large rooms: protection against emission of toxic or explosive gases with locally controlled signaling devices.

Construction and characteristic features

The detector is distinguished by a solid construction and a number of functions facilitating installation, configuration and operation:

• Replaceable sensor module: Enables quick replacement of a damaged sensor or adaptation to other measurement needs (compatible with DG/F and DG/P modules). This reduces maintenance costs and extends the life of the device.
• Two alarm thresholds: Allow for flexible setting of warning and alarm levels, tailored to the specifics of a given application.
• Screwless terminals: Facilitate connection of power and signal wires, saving time during installation.
• Semi-automatic addressing: Simplifies the configuration of a network of detectors without the need to open the device housing.
• Configuration via DETnet View software: Intuitive configuration software allows for remote setting of detector parameters and monitoring of its operation (available from the manufacturer).
• Built-in microprocessor: Ensures stable and reliable operation of the device and thermal compensation of the measurement.
• Alarm status history: Enables analysis of events and identification of potential problems in the installation.

The device is powered by 24V= voltage and its compact dimensions (110 x 140 x 55 mm) allow for easy mounting in various locations. It should be remembered that DG/MR detectors are not intended for use in areas hazardous due to the explosion of gases, vapors or dusts – these are devices of conventional construction. All GAZEX detectors are calibrated in their own Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees measurement accuracy and compliance with applicable standards.
