Gas detector DEX-P1R2/N methane, 100% Methane, P4-C construction, IR sensor, brass housing

Gas detectors DEX/P – reliable safety in any environment

Gas detectors of the DEX/P series are devices designed for continuous monitoring of gas or vapor concentrations in enclosed spaces. They utilize advanced sensors, including optical (Infra-Red), catalytic, electrochemical, and semiconductor sensors, which allows for precise detection of hazards and ensuring safety in various industrial and commercial applications. Model DEX-P1R2/N, equipped with an IR sensor, is dedicated to measuring methane in the range of 100% LEL (Lower Explosive Limit).

Construction and application

DEX/P detectors are characterized by a robust explosion-proof construction (flameproof enclosure type), which enables their safe use in areas threatened by the explosion of flammable gases or vapors (explosion groups IIA, IIB, IIC and temperature classes T1-T6). The housing made of brass ensures durability and corrosion resistance. The device has an analog current output of 4-20mA, which facilitates integration with control and alarm systems. The DEX-P1R2/N detector is ideal for gas installations, wastewater treatment plants, mines, as well as in the chemical and petrochemical industries.

Advantages and benefits

• High measurement accuracy: The IR sensor provides accurate and reliable measurements of methane concentration.
• Safety: Explosion-proof construction guarantees safe operation in potentially hazardous environments.
• Versatility: Possibility of cooperation with various control modules (MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16; MDD-1, MDD-1/T, MDD-1x/T) and control panels accepting a 4-20mA signal.
• Durability: Brass housing provides resistance to mechanical damage and corrosion.
• ATEX certification: Compliance with the requirements of Directive 2014/34/EU guarantees compliance with European safety standards.
• Replaceable sensor: Allows for easy replacement of a damaged or worn element without the need to replace the entire detector – reduces operating costs.
• Calibration: Each detector is factory calibrated in the GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025.

The DEX-P1R2/N detector is a reliable tool for monitoring methane concentration, which ensures the safety of people and property. Its robust construction, precise measurements and ease of integration with existing systems make it an ideal choice for both professional installers and end users.
