Gas detector DEX-P1KL5/N for propane-butane, measurement range 100% LEL, catalytic sensor, construction P4-C, aluminum housing

Gas Detectors – Reliable Protection and Precise Measurement

Gas detectors of the DEX/F series are designed for continuous monitoring of flammable, toxic, or oxygen concentrations in enclosed spaces. They are widely used across industrial facilities, ensuring safety and enabling rapid response in case of exceeding permissible limits. The DEX-P1KL5/N model, equipped with a catalytic sensor, is specifically dedicated to precise measurement of propane-butane (LPG) concentrations up to 100% LEL.

Design and Application

The DEX-P1KL5/N detector features a robust explosion-proof construction with an aluminum housing, enabling safe operation even in explosive atmospheres (Zone 1 and 2, Groups IIA, IIB, IIC). The device is compatible 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 central units accepting a 4–20 mA signal. This allows seamless integration into existing gas monitoring systems. The 4–20 mA analog output also enables connection to automation and data logging systems.

Advantages and Benefits

• High measurement precision: The catalytic sensor ensures accurate and reliable readings of propane-butane concentration.
• Safety: Explosion-proof construction and ATEX certification guarantee safe operation in potentially hazardous environments.
• Versatility: Compatibility with multiple control modules and central units simplifies integration into existing systems.
• Long-term reliability: Replaceable catalytic sensor extends device lifespan and reduces operational costs.
• Calibration standards: All detectors are calibrated in GAZEX’s own Accredited Calibration Laboratory, certified according to PN-EN ISO/IEC 17025.
• Fast installation: Modular design and no need for on-site calibration significantly accelerate commissioning.
• Broad application range: Ideal for monitoring gas installations in residential and industrial buildings, as well as in vehicles transporting LPG.

The DEX-P1KL5/N detector is a reliable solution for gas system installers and end-users seeking effective protection against propane-butane gas leaks. Its robust construction, precise measurements, and easy integration make it the ideal choice for demanding applications.
