Hydrogen Sulfide Detection – Reliability and Precision

The DG-P5E/M gas detector is an advanced device designed for continuous monitoring of hydrogen sulfide (H2S) concentrations in various industrial and public utility environments. Its purpose is to detect dangerous gas levels early, ensuring worker safety and protecting installations. This detector is an integral part of the GAZEX Digital Gas Detection System, enabling comprehensive air quality monitoring.

Construction and Operating Principle

The device utilizes an electrochemical sensor characterized by high selectivity and measurement accuracy. When defined alarm thresholds are exceeded, the detector activates an optical signal, and hazard information is transmitted to the central supervisory module via an RS-485 interface with the MODBUS RTU protocol. The replaceable sensor module facilitates maintenance, calibration, and reduces operating costs.

The DG-P5E/M detector has a splash-proof housing (IP44) made of durable ABS, ensuring its reliability in harsh industrial conditions. Two cable glands allow easy connection of additional detectors in a network. Additionally, the device is equipped with a thermal compensation circuit, ensuring measurement stability at varying temperatures. The ability to expand with additional relay outputs (DG-P/MR version) increases the device's functionality and allows integration with existing alarm systems.

Applications and Benefits

The DG-P5E/M detector is used in:

• industrial plants (e.g., wastewater treatment plants, refineries),
• logistics centers,
• public utility facilities (e.g., wastewater treatment plants),
• large rooms at risk of toxic gas emissions.

Benefits of use:

• High measurement accuracy: The electrochemical sensor provides precise detection of even low concentrations of H2S.
• Fast response: The detector's short response time minimizes the risk of exposure to dangerous gas levels.
• Easy maintenance: The replaceable sensor module simplifies calibration and reduces operating costs.
• System integration: RS-485 communication enables integration with the GAZEX Digital Gas Detection System and other control and monitoring systems.
• Reliability: The durable housing and high-quality components ensure long-lasting and trouble-free operation of the device.
• Configuration: Detector settings can be configured using the dedicated "DETnet View" software.
• Calibration: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150).

The device is powered by 24 V= and its dimensions are 110 x 140 x 55 mm. Thanks to its compact size and simple installation, the DG-P5E/M detector can be easily installed anywhere requiring hydrogen sulfide concentration monitoring.
