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

Gas detectors DG-7E/M – reliable protection against hydrogen leakage

The DG-7E/M gas detector is an advanced device designed for continuous monitoring of hydrogen concentration in various environments. It utilizes an electrochemical sensor, providing precise measurement in the range of 500-800 ppm. This detector finds application in industrial plants, logistics centers, and public buildings, where rapid detection of potential hazards related to the presence of hydrogen is crucial.

Wide application and high functionality

Detectors from the DG/M series, including the DG-7E/M model, are an integral part of the GAZEX Digital Gas Detection System. They enable real-time monitoring of gas concentrations, and in the event of exceeding permissible norms, activate optical signaling and transmit information to the supervisory module via the RS-485 network with the MODBUS RTU protocol. A replaceable sensor module facilitates maintenance and calibration, reducing operating costs.

Construction and user features

The device is characterized by a splash-proof housing made of high-impact ABS (IP44), which ensures its durability and resistance to mechanical damage. Two cable glands facilitate connecting subsequent detectors in a network. A built-in microprocessor guarantees stable operation and semi-automatic addressing in a digital network. Additionally, the detector has a thermal compensation circuit and a history of alarm states, allowing for a thorough analysis of events. Configuration of settings is done using the dedicated "DETnet View" software.

• RS-485 communication with MODBUS RTU protocol enables integration with control and monitoring systems.
• Replaceable sensor module ensures easy maintenance and calibration.
• Fast detector response time due to the relatively short permeability of gases through the sensor cover.
• Built-in microprocessor ensures reliable and stable operation of the device.
• Possibility of expansion with additional functions, such as relay outputs (DG/MR version).
• 24V= power supply ensures compatibility with various energy sources.
• All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation no. AP150).

Applications

The DG-7E/M detector is ideal for use in the following places:

• Industrial plants – monitoring hydrogen concentration in production processes.
• Logistics centers – control of safety during storage and transport of materials containing hydrogen.
• Public buildings – protection against hydrogen leaks in residential, office and commercial buildings.
• Large rooms threatened by the emission of toxic or explosive gases – ensuring safe working and operating conditions.

Please note that DG/M detectors cannot be used in areas classified as zones hazardous due to the explosion of gases, vapors or dusts due to their ordinary construction.
