Gas detector DG-A12/N-Nstd DG-A12/N-NSTD

Gas detector DG-A12/N-Nstd – reliable methane detection

The DG-A12/N-Nstd gas detector is an advanced device designed for continuous monitoring of methane (CH₄) concentration in industrial and enclosed spaces. It utilizes a semiconductor gas sensor, providing a fast and precise response to hazards. The detector is powered by the system, simplifying integration with existing infrastructure. Its splash-proof housing makes it resistant to harsh environmental conditions.

Functionality and application

The DG-A12/N-Nstd device is a two-threshold detector, meaning it has two independently adjustable alarm thresholds (set during production). Additionally, a built-in third threshold indicates the upper measurement range of the gas sensor. The 4-20 mA interface allows easy connection to control and data logging systems. The detector is particularly useful in places where there is a risk of explosion or methane poisoning – in industrial plants, mines, sewage treatment plants or gas storage facilities.

Key features and benefits

• Replaceable sensor: Intelligent semiconductor gas sensor ensures easy replacement and calibration of the device. This translates to minimal downtime and low operating costs.
• Two alarm thresholds: Allow precise adjustment of the detector's sensitivity to specific working conditions and applicable safety standards.
• 4-20 mA interface: Ensures compatibility with most control and monitoring systems, enabling remote reading and control.
• Built-in event history: Allows analysis of the causes of alarms and optimization of the gas detection system. Available after sending the device to the Manufacturer.
• Calibration period expiry signal: Reminds of the need for regular calibration, ensuring continuous measurement reliability.
• Built-in test procedure: Facilitates identification of output wires during installation and service.
• Accredited calibration: All detectors are calibrated in a GAZEX laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation no. AP150), which guarantees the accuracy and reliability of measurements.
• Compact dimensions: The housing with dimensions of 110 x 153 x 60 mm facilitates mounting in tight spaces.

The DG-A12/N-Nstd detector is designed to detect methane in the range of 10/30/(40) %LEL.

The DG-A12/N-Nstd detector is an investment in safety and work comfort – for both installers and end-users. Its reliability, precision and ease of integration make it an ideal solution for demanding industrial applications.
