Gas detector DG-P3R/N organic compounds, 100% LEL, IR sensor

Gas detectors for industrial and domestic applications

The DG/P series gas detectors are devices designed for continuous monitoring of the presence of harmful or dangerous substances in the air. They are used in industrial and enclosed premises, as well as in residential buildings, where there is a risk of gas leakage. These devices signal exceeding the permissible concentration norms of gases, ensuring the safety of people and property. The DG-P3R/N model, equipped with an optical sensor (Infra-Red), is dedicated to detecting organic compounds.

Construction and principle of operation

DG/P detectors are characterized by a solid construction and ease of operation. They have an analog 4-20 mA output, which allows easy integration with control and alarm systems. A splash-proof housing provides protection against moisture and dust. A replaceable sensor module with thermal and linear compensation algorithms guarantees precise measurements and long-term reliability. The optical sensor (Infra-Red) in the DG-P3R/N model uses the absorption of infrared radiation by organic compounds for their detection, which ensures high selectivity and measurement accuracy.

Advantages and benefits

• Wide application: ideal for monitoring the concentration of organic compounds in various industrial and commercial environments.
• High accuracy: the optical sensor (Infra-Red) provides precise measurements and minimizes the risk of false alarms.
• Easy integration: the analog 4-20 mA output allows connection to existing control and alarm systems.
• Low maintenance: replaceable sensor modules allow for quick and easy replacement of damaged elements without the need for calibration at the installation site.
• Calibration standards: all detectors are calibrated in their own GAZEX Calibration Laboratory, accredited according to PN-EN ISO/IEC 17025, which guarantees the reliability of measurements.
• Simple installation: modular design and no need for on-site calibration simplify the design and installation process of the gas detection system.
• Durable construction: a splash-proof housing protects the device from external factors, ensuring long-term reliability.

Applications

The DG-P3R/N detector is used in:

• Chemical industry – monitoring leaks of solvents, paints and other organic compounds.
• Food industry – control of gas concentrations generated during fermentation or storage of food products.
• Automotive workshops – detection of gasoline, oil and other petroleum substance vapors.
• Gas stations – monitoring the presence of fuel leaks.
• Warehouses – control of gas concentrations emitted by stored materials.
• Ventilation systems – controlling the operation of fans depending on the gas concentration in the air.
• Residential buildings - protection against carbon monoxide or other dangerous gases poisoning (requires proper calibration).

Additional information

The device is designed to cooperate with various control units, both from GAZEX (e.g. MDP-1 PLUS, MDD-1) and from other manufacturers accepting the 4-20 mA signal. The dimensions of the detector are 110 x 140 x 55 mm, and its weight is approximately 0.3 kg. This ensures easy installation even in hard-to-reach places.
