Gas detector DEX-1KL5/N propane-butane, calibration 10/30 % LEL, catalytic sensor, execution F4-C, aluminum housing

Gas detectors – protection and safety

The DEX/F series detectors are designed for continuous monitoring of air in enclosed spaces for the presence of explosive gases, toxic substances, or oxygen deficiency. These devices signal exceeding defined alarm thresholds (A1 and A2), set in the replaceable sensor module. This ensures a quick response in the event of a hazard and minimizes the risk of dangerous situations.

Design and application

The DEX-1KL5/N detector is an explosion-proof device, made in an aluminum housing, designed for detecting propane-butane. Equipped with a catalytic sensor, it reacts to the presence of gas in the range of 10-30% Lower Explosive Limit (LEL). This model finds application both in domestic and industrial installations where there is a risk of flammable gas leakage. Thanks to ATEX certification, the detector can be used in potentially explosive zones (IIA, IIB or IIC), making it an ideal solution for industrial plants, warehouses and other places requiring a high level of safety.

Advantages and benefits

• High reliability: Explosion-proof design and ATEX certification guarantee safe use even in difficult conditions.
• Precise measurement: The catalytic sensor provides accurate detection of propane-butane over a wide range of concentrations.
• Easy sensor replacement: The replaceable sensor module enables quick and easy calibration and maintenance of the device, minimizing operating costs.
• Wide application: The detector is compatible with various control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, MDD-1, MDD-1/T, MDD-1x/T), allowing integration with existing alarm and control systems.
• Calibration: Each detector is factory calibrated in its own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which ensures measurement accuracy and compliance with applicable standards.
• Durable construction: The aluminum housing provides resistance to mechanical damage and corrosion.

Additional information

DEX/F detectors are modular devices, which means the system can be easily expanded with additional functions and sensors. Proper placement of the detector is important – it should be installed in a place where gas may potentially accumulate, in accordance with the manufacturer's recommendations. Regular calibration of the detector is crucial to ensure its correct operation and measurement reliability.
