Gas Detectors DEX/F – Reliable Protection Against Hazards

Gas detectors of the DEX/F series are devices designed to detect dangerous concentrations of gases or vapors of explosive, toxic liquids, or oxygen in enclosed industrial premises. They signal exceeding two alarm thresholds, set in a replaceable sensor module. The explosion-proof design makes these detectors suitable for use even in demanding conditions, in areas at risk of explosion.

Application and Compatibility

DEX/F detectors work with various control modules, providing flexibility and the ability to adapt the system to individual needs:

• Threshold modules: MD-1.A/T, MD-1, MD-2, MD-4
• Measurement-threshold modules: MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16
• Addressable modules: MDD-1, MDD-1/T, MDD-1x/T

Construction and Characteristics

DEX/F detectors are characterized by a solid construction and high quality workmanship. The housing made of brass ensures durability and corrosion resistance. A replaceable sensor module with thermal and linear compensation algorithms and a weighted average calculation function (NDS, NDSCh) guarantees precise and reliable measurements. The ability to replace sensors translates into low operating costs and a long device life. The DEX-8R/N detector uses an optical sensor (Infra-Red) to detect carbon dioxide (CO2) in the range of 0.5/1.5 %v/v. The device is designed to be powered from an external system.

Safety and Compliance with Standards

DEX detectors meet the essential requirements of Directive 2014/34/EU (ATEX), confirming their safety and suitability for use in potentially explosive atmospheres. They have a KDB 04ATEX133X certificate along with Supplementary Certificates. The devices are calibrated in their own GAZEX Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150).

Key Advantages of DEX/F Detectors:

• Explosion-proof design: Safe operation in areas at risk of explosion.
• Replaceable sensor: Low operating costs and easy calibration.
• High measurement accuracy: Compensation algorithms ensure reliable results.
• Modularity: Ability to adapt to different control systems.
• ATEX compliance: Guarantee of safety and legality of use.
• Durable brass housing: Resistance to corrosion and mechanical damage.
• Specialization: DEX-8R/N model dedicated to precise measurement of carbon dioxide (CO2).
