Gas detector DG-6R7/N-SF6 SF6, 500/1500 ppm, IR sensor

Gas detectors of the DG/F series – reliable safety in industry

The DG/F gas detectors are devices designed for continuous monitoring of hazardous gas or liquid vapor concentrations in industrial environments and enclosed spaces. Equipped with replaceable sensor modules with two alarm thresholds, they provide effective protection against hazards caused by explosion, toxicity, or oxygen deficiency. The DG-6R7/N-SF6 model, with an optical IR sensor, is dedicated to precise detection of SF6 in the range of 500-1500 ppm.

Design and application

The DG/F detectors are characterized by a modular design, which facilitates servicing and calibration. Replacing the sensor module is simple and quick, minimizing system maintenance costs. These devices find application in a wide range of industrial facilities, such as:

• Power plants and substations – monitoring SF6 leaks from high-voltage equipment.
• Chemical and petrochemical plants – detection of leaks of toxic and explosive gases.
• Production halls – control of gas concentrations generated during technological processes.
• Warehouses and storage facilities – protection against the accumulation of hazardous substances.
• Tunnels and underground parking garages – monitoring oxygen levels and exhaust gas presence.

It is important to remember that the DG/F detectors have a standard construction and cannot be used in areas at risk of explosion of gases, vapors, or dust.

Advantages and benefits

• Replaceable sensor module: Allows for quick replacement of a damaged element or adaptation of the detector to other applications without the need to replace the entire device.
• Optical signaling: Built-in LEDs inform about the detector's operating status and exceeding alarm thresholds.
• Thermal compensation: Ensures measurement stability even under changing environmental conditions.
• Splash-proof housing (IP44): Protects the device from moisture and dust, ensuring reliable operation in harsh industrial conditions.
• Accredited calibration: All detectors are calibrated in their own GAZEX Calibration Laboratory, accredited according to PN-EN ISO/IEC 17025 (PCA No. AP150), which guarantees measurement accuracy.
• Wide range of applications: Availability of various sensor modules allows adaptation of the detector to specific user needs – the DG-6R7/N-SF6 model is ideal for monitoring SF6.
• Simple installation and operation: Modular design and no need for calibration at the installation site facilitate the design and commissioning of the gas detection system.

The DG-6R7/N-SF6 detector with an IR sensor is a precise tool for monitoring SF6 concentration, ensuring safe operation in high-voltage installations and minimizing the risk of failures related to leaks of this gas. Its reliability is confirmed by numerous certificates and accreditation of the GAZEX calibration laboratory.
