Gas detector DG-P7KL3/M hydrogen, range 100% LEL, catalytic sensor, RS-485

Gas detectors of the DG-P/M series – reliable hydrogen presence control

The DG-P/M gas detectors are devices designed for continuous monitoring of gas concentrations in various environments – from industrial plants and logistics centers to public utility facilities. The DG-P7KL3/M model, equipped with a catalytic sensor, is dedicated to the precise detection of hydrogen in a range of up to 100% LEL (Lower Explosive Limit). Optical alarm signaling and transmission of information to a digital supervisory module via the RS-485 interface with the MODBUS RTU protocol ensure a rapid response in the event of exceeding permissible levels.

Construction and functionality for professionals and end-users

The construction of DG-P/M detectors is based on interchangeable sensor modules – semiconductor, electrochemical or optical. This solution facilitates maintenance, calibration and reduces operating costs. Replacing a damaged sensor is simple and does not require specialized knowledge. The device has a built-in microprocessor that ensures stable operation and semi-automatic addressing in a digital network – configuration is intuitive and does not require opening the housing. In addition, the thermal compensation circuit minimizes the impact of temperature changes on measurement accuracy. The detector records the history of alarm states, which facilitates event analysis. A splash-proof ABS housing (IP44) protects against moisture and dust. Two cable glands allow easy connection of subsequent detectors in the system.

Key features and benefits

• Hydrogen detection: A catalytic sensor provides a precise measurement of hydrogen concentration in a range of up to 100% LEL. This is crucial for safety in applications related to the production, storage or use of hydrogen as a fuel.
• RS-485 communication: The RS-485 standard with the MODBUS RTU protocol enables integration of the detector with existing monitoring and control systems.
• Interchangeable sensor modules: Allow for quick replacement of a damaged sensor and adaptation of the detector to various applications by selecting the appropriate sensor type.
• High reliability: The built-in microprocessor and thermal compensation circuit ensure stable and accurate operation of the device.
• Easy configuration: Semi-automatic addressing in a digital network and dedicated configuration software „DETnet View” simplify the installation and configuration process.
• Compliance with standards: All detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees the reliability of measurements.
• Solid construction: A splash-proof housing made of high-impact ABS (IP44) provides protection against harsh environmental conditions.

The DG-P7KL3/M detector is a reliable solution for anyone who needs effective control of hydrogen presence in their work or usage environment.
