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

Product features

Gas detector designed for detecting organic compounds.

This gas detector, based on an optical sensor (infrared), is designed to precisely detect the presence of dangerous concentrations of organic compounds in the air. The device is used in industrial and enclosed spaces where air quality monitoring is crucial for safety. It is a component of gas detection systems, cooperating with control modules, enabling a quick response to a threat.

Construction and principle of operation

The DG-3R/N detector is a threshold device, equipped with two independent alarm thresholds set at the factory and an additional threshold indicated optically. It uses optical technology (IR), which ensures high selectivity and accuracy in measuring organic compounds. The alarm signal is realized both optically (built-in LED) and through binary outputs, allowing integration with control and alarm systems. A built-in test procedure facilitates checking the correct connection of the output cables after installation. The thermal compensation circuit minimizes the impact of ambient temperature changes on measurement accuracy.

Applications and benefits

This detector is ideal for applications requiring reliable monitoring of organic compound concentrations, such as:

• Chemical industry: Control of leaks of solvents and other organic substances.
• Automotive workshops: Monitoring the concentration of gasoline and other fuel vapors.
• Food industry: Detection of gases generated during fermentation or storage of products.
• Warehouses: Control of the concentration of gases emitted by stored materials.
• Ventilation systems: Integration with ventilation systems to automatically start ventilation when a threat is detected.

It is worth emphasizing that the modular design of the detector facilitates sensor replacement in the event of calibration or repair, reducing operating costs. All GAZEX detectors are calibrated in their own laboratory accredited according to the PN-EN ISO/IEC 17025 standard, which guarantees their accuracy and measurement reliability. A splash-proof housing (IP44) provides resistance to harsh environmental conditions.
