Gas detector DG-7E/MR hydrogen, 500/800ppm, electrochemical sensor

Gas detectors DG-7E/MR – reliable protection against hydrogen leaks

The DG-7E/MR gas detector is an advanced device designed for continuous monitoring of hydrogen concentration in various environments. It utilizes an electromechanical sensor, offering precise measurement in the range of 500-800 ppm. Audible and visual alarm signaling, combined with RS-485 communication and two relays, ensures a rapid response in case of exceeding permissible norms. The detector finds application in industrial plants, logistics centers, and public utility facilities.

Functionality and application

The device is designed to work with a Digital Gas Detection System, enabling central supervision of multiple measurement points. Built-in relays and an RS-485 interface with the MODBUS RTU protocol allow integration with existing control and alarm systems. A replaceable sensor module facilitates maintenance, calibration, and reduces operating costs. The detector will prove useful wherever continuous monitoring of hydrogen concentration is required – from laboratories to warehouses and production halls.

Key features and benefits

• Precise measurement: The electromechanical sensor ensures accurate determination of hydrogen concentration in the range of 500-800 ppm.
• Fast response: Built-in optical signaling and two relays enable immediate notification of exceeding permissible norms.
• RS-485 communication: Enables integration with control and monitoring systems via the standard MODBUS RTU protocol.
• Replaceable sensor module: Facilitates maintenance, calibration, and reduces operating costs. Allows for quick replacement of a damaged sensor or adaptation to other measurement needs.
• Universal application: Ideal for use in industrial plants, logistics centers, and public utility facilities.
• Standards and calibration: All detectors are calibrated in their 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.
• Easy configuration: Detector settings can be configured using the dedicated "DETnet View" software.
• Solid construction: The device is made of high-impact ABS/PC providing durability and resistance to mechanical damage.

The DG-7E/MR detector has two relay control outputs, communicates via the RS-485 interface, and has a built-in optical signal. The device is powered by 24V= voltage and its dimensions are 110 x 140 x 55 mm.

The DG-7E/MR detector is a reliable solution for anyone who needs effective protection against hydrogen leaks. Its precision, functionality, and ease of use make it an ideal choice for both professional installers and end-users. However, remember that the device is intended for use in areas not classified as zones hazardous due to the explosion of gases, vapors, or dust – it is a detector with a conventional construction.
