Gas detector DG-0E.ETO/MR ethylene oxide, 2/5 ppm (cross-calibration), electrochemical sensor

Gas detectors – reliable protection in industrial plants and beyond

Digital detectors of the DG/MR series are devices designed for continuous monitoring of gas presence in rooms. Their task is to measure the gas concentration in the air and, in the event of exceeding defined thresholds, activate an alarm signal and transmit information to the central monitoring system via the RS-485 interface. These detectors work perfectly in industrial plants, logistics centers, public utility facilities, and anywhere where there is a risk of emission of toxic or explosive gases.

DG/MR detectors are characterized by a modular design, allowing for easy replacement of sensor modules – semiconductor, electrochemical, or optical (Infra-Red). This feature significantly simplifies maintenance, calibration, and reduces operating costs. It is worth remembering that these are devices of ordinary construction and should not be used in explosion-hazard zones.

Functionality and application

The DG-0E.ETO/MR detector is designed to detect ethylene oxide in the range of 2/5 ppm (with cross-calibration). It uses an electrochemical sensor, which ensures high measurement accuracy. The device has two low-voltage relay outputs and communicates via the RS-485 standard with the MODBUS RTU protocol.

Thanks to this, the detector can be integrated with a gas detection system, enabling central monitoring of safety in the facility. Built-in relays allow for direct control of alarm devices or ventilation systems.

Advantages and benefits

• Replaceable sensor module: Facilitates maintenance and calibration, reducing operating costs.
• RS-485 communication: Enables integration with the monitoring system and remote monitoring of the detection status.
• Two alarm thresholds: Allow for flexible adaptation to specific application requirements.
• High sensor selectivity: Ensures precise detection of ethylene oxide, minimizing the risk of false alarms.
• Cross-calibration: Expands the sensor's application range, allowing the detection of other gases with similar properties (taking into account the potential measurement error).
• Configuration via DETnet View software: Enables easy adjustment of the detector settings to individual needs.
• Calibration in an accredited GAZEX laboratory: Guarantees the accuracy and reliability of measurements (compliance with PN-EN ISO/IEC 17025 standard).
• Thermal compensation: Ensures stable measurements regardless of ambient temperature.
• Semi-automatic addressing: Facilitates installation and configuration on a digital network without the need to open the housing.

The DG-0E.ETO/MR detector is a solid and reliable device that will provide effective protection against hazards related to the presence of ethylene oxide in the air – both for installers looking for easy-to-install and configure equipment, and for end-users expecting a reliable gas detection system.
