Gas detector DEX-1R5/N-Nstd propane-butane, calibration on request, execution F4-C, IR sensor, brass housing DEX-1R5/N-NSTD

Propane-butane gas detector – reliable protection in hazardous areas.

This gas detector, designed to detect propane and butane (LPG), is a key element of safety systems in places where there is a risk of explosion. The device, made in a brass housing with an explosion-proof design, meets stringent ATEX standards, allowing for its safe use in potentially explosive atmospheres (IIA, IIB, IIC). Thanks to the use of an optical (IR) sensor, it provides precise and reliable gas concentration measurement.

Construction and application

The DEX-1R5/N detector is part of comprehensive gas leak detection systems. It works with various GAZEX 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 and MDD-1, MDD-1/T, MDD-1x/T), enabling a quick response in the event of exceeding the permissible gas concentration levels. The detector's design is intended for easy surface mounting. Replaceable sensor modules with built-in compensation algorithms ensure long-term and stable device operation.

Key features and benefits

• Safety confirmed by ATEX certificate: Possibility of use in potentially explosive atmospheres – a guarantee of protection for people and property.
• Precise measurement thanks to IR sensor: High accuracy of propane and butane detection minimizes the risk of false alarms and ensures a quick response to real threats.
• Durable brass housing: Resistance to mechanical damage and corrosion – long-term reliability even in harsh industrial conditions.
• Modular design: Easy replacement of sensor modules – reduced operating costs and the ability to adapt to different applications.
• Calibration in an accredited laboratory: Detectors are calibrated in their own GAZEX Calibration Laboratory (PCA accreditation No. AP150), which ensures compliance with standards and measurement accuracy.
• Quick installation and ease of use: Facilitates installation and configuration for installers and intuitive operation for end users.
• Two alarm thresholds: Signaling of exceeding two set alarm thresholds (A1, A2) – increased safety level by gradually warning of danger.

The DEX-1R5/N detector is not only a device signaling a gas leak – it is an investment in safety and peace of mind. Its solid construction, measurement accuracy and compliance with ATEX standards make it an ideal solution for both professional gas system installers and end users who care about safety in their surroundings. The device is factory calibrated to alarm thresholds of 10% and 30% LEL (Lower Explosive Limit).
