Methane detector DG-1R2/N-Nstd – reliable explosion protection

The DG-1R2/N-Nstd gas detector is an advanced device designed for continuous monitoring of methane concentration in industrial and enclosed spaces. It utilizes an optical sensor (Infra-Red), which ensures high measurement accuracy and a fast response time. The detector is part of the GAZEX gas detection system, designed to provide early warning of dangerous gas levels, minimizing the risk of explosion and ensuring the safety of people and property.

Construction and application

The device belongs to the group of threshold, system gas detectors DG/F. Its construction is based on an exchangeable sensor module, which facilitates servicing and calibration. The detector is designed to cooperate with control modules of the MD and MDP series, enabling integration with comprehensive monitoring and control systems. It finds application in industrial plants, logistics centers, public utility facilities, and everywhere where there is a risk of methane leakage. Thanks to its compact dimensions (110 x 140 x 55 mm) and the possibility of mounting in various configurations (including on ventilation ducts), the detector can be easily adapted to the specifics of a given facility.

Functionality and benefits

• High measurement accuracy: The optical sensor (Infra-Red) guarantees accurate detection of methane even at low concentrations.

• Two alarm thresholds: Alarm thresholds set during production allow for a quick response in case of exceeding the permissible gas concentration levels. An additional threshold indicates the upper measurement range of the sensor.

• Exchangeable sensor module: Enables easy replacement of a damaged sensor or adaptation to other gases (after purchasing the appropriate module). This reduces operating costs and downtime.

• Optical signaling: A built-in multi-color LED lamp informs about the detector's status and exceeding alarm thresholds.

• Event history: Built-in memory stores event history, which facilitates analysis of alarm causes and optimization of system operation.

• Thermal compensation: Thermal compensation circuit ensures stable readings even under variable environmental conditions.

• Power from the system: Enables integration with existing power and control infrastructure.

• Accredited calibration laboratory: Detectors are calibrated in GAZEX's own laboratory, accredited according to PN-EN ISO/IEC 17025 (PCA accreditation no. AP150), which guarantees the reliability of measurements.

The DG-1R2/N-Nstd detector is an investment in safety that allows for effective protection against hazards related to the presence of methane in the air. Its reliability, measurement accuracy, and ease of use make it an ideal solution for both professional installers and end-users who care about safety in their facilities.
