Gas detector DG-3R/MR-Nstd for organic compounds, field calibration, IR sensor DG-3R/MR-NSTD

Gas detector – reliable protection against hazards

This gas detector is designed for continuous monitoring of organic compounds in rooms. The device measures the concentration of gas in the surrounding air and, if defined thresholds are exceeded, activates optical signaling, switches on built-in relays, and sends information to the supervisory system via the RS-485 interface. This is a key solution for ensuring safety in industrial plants, logistics centers, and public facilities.

The DG-3R/MR detector uses an optical sensor (Infra-Red) for precise detection of organic gases. The replaceable sensor module simplifies maintenance, simplifies calibration, and reduces operating costs. The device is powered by 24V= and has two switching relay outputs. Communication is via the RS-485 standard with the MODBUS RTU protocol, enabling integration with automation and monitoring systems.

Application and functionality:

• Wide range of applications: ideal for monitoring in industrial plants, logistics centers, public facilities, and large rooms at risk of emissions of toxic or explosive gases.
• High measurement accuracy: the Infra-Red sensor provides accurate detection of organic compounds in the range of 20/40% LEL (Lower Explosive Limit).
• Configuration flexibility: ability to set two alarm thresholds or measurement mode.
• Easy integration: RS-485 communication with the MODBUS RTU protocol allows for seamless connection to existing monitoring systems.
• Replaceable sensor module: quick and easy sensor replacement minimizes downtime and service costs.
• Solid construction: the detector is designed for surface mounting and is characterized by compact dimensions (110 x 140 x 55 mm).
• Built-in protection: two relays with NO/NC contacts ensure reliable operation in emergency situations.

The DG-3R/MR detector complies with the PN-EN ISO/IEC 17025 standard thanks to calibration in the GAZEX Calibration Laboratory, which guarantees high quality and reliability of measurements. It also has semi-automatic addressing in a digital network, which simplifies installation and configuration. Additionally, the device offers a history of alarm states, allowing for event analysis and optimization of the gas detection system.
