Gas detectors of the DEX/F series – reliable protection against hazards

The gas detectors of the DEX/F series are devices designed for continuous monitoring of the concentration of gases or vapors of liquids in enclosed spaces. They find application both in industrial installations and in public buildings, ensuring the safety of people and property. Explosion-proof construction and ATEX certification allow them to operate in potentially explosive areas.

Construction and application

The DEX-P1R5/N detector, using an optical sensor (Infra-Red), is dedicated to detecting propane and butane in the range of 100% LEL (Lower Explosive Limit). The device is characterized by high selectivity and measurement stability, which translates into reliable detection. The 4-20mA analog output allows for easy integration with control and alarm systems, such as MDP-1.A/T, MDP-1 PLUS, MDD-1 or other control panels accepting the standard 4-20mA input line. Thanks to the explosion-proof construction (flameproof enclosure type), the detector can be installed in zones 1 or 2 hazardous due to the presence of gases from group IIA, IIB or IIC.

Key features and benefits

• High selectivity: The IR sensor provides a precise measurement of propane and butane concentration, minimizing the risk of false alarms.
• Explosion-proof construction: Ensures safe operation in potentially explosive atmospheres, confirmed by ATEX certification.
• Versatility: The ability to cooperate with various control modules and alarm panels increases the flexibility of the system.
• Replaceable sensors: Allow for quick replacement of a damaged sensor without the need to replace the entire detector, reducing operating costs.
• Calibration standards: Each detector is calibrated in its own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025, which guarantees measurement accuracy.
• Simple installation: Modular construction and no need for calibration at the installation site facilitate and speed up the installation process.
• Durable housing: Made of brass, it provides resistance to corrosion and mechanical damage.

The DEX-P1R5/N detector is a solid solution for installers looking for a reliable and precise device for detecting propane-butane gases and for end-users who value safety and comfort of use.
