Gas detector DG-12/MR-Nstd methane, field calibration, proportional sensor DG-12/MR-NSTD

Methane detection with a reliable semiconductor sensor

This gas detector is designed for continuous monitoring of methane concentration in rooms. The device, utilizing a semiconductor sensor, signals exceeding permissible gas concentration levels both visually and through built-in relays. This solution is ideal for anywhere where constant methane monitoring is required – from gas installations, through industrial facilities, to public spaces.

Construction and functionality

The DG-12/MR-Nstd detector features a modular design. A replaceable sensor module facilitates maintenance and calibration, and also lowers operating costs. Communication is via an RS-485 port with the MODBUS RTU protocol, enabling integration with the Digital Gas Detection System. Two programmable alarm thresholds and built-in NO/NC relays provide configuration flexibility and rapid response in the event of a hazard.

• Fast response: Short gas permeability time through the sensor cover ensures almost instantaneous methane detection.
• High stability: Built-in microprocessor guarantees reliable and stable device operation.
• Thermal compensation: Thermal compensation circuit minimizes the impact of temperature changes on measurement accuracy.
• Alarm history: Recording of alarm states facilitates analysis of the causes of failures and optimization of the detection system.
• Easy installation: Screwless terminals simplify wire connection, and two cable glands allow connecting subsequent detectors in a network.
• Calibration: Possibility of custom calibration ensures measurement accuracy tailored to specific application needs.

The DG-12/MR-Nstd detector is a product of the GAZEX brand, which has an accredited calibration laboratory (PN-EN ISO/IEC 17025, PCA accreditation No. AP150), confirming the high quality and accuracy of measurements. The device is designed to work with the GAZEX Digital Gas Detection System, offering a comprehensive solution for gas presence monitoring.
