Gas detector DEX-P4K/N – reliable protection against ammonia leakage

The DEX-P4K/N gas detector is an advanced device designed for continuous monitoring of ammonia concentration in enclosed spaces. Equipped with a catalytic sensor, the detector provides precise measurement in a range of up to 20% LEL (Lower Explosive Limit). A solid brass housing with a steel sinter guarantees durability and corrosion resistance, and the explosion-proof design allows safe use even in potentially hazardous environments.

The DEX-P4K/N detector is compatible with various control and alarm systems, including MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16 modules, as well as addressable MDD-1, MDD-1/T, MDD-1x/T modules. The ability to cooperate with other control panels accepting a 4-20mA signal (after using the MDPL1 power limiter) provides installation flexibility. The device meets the requirements of the ATEX Directive, confirming its safety and compliance with European standards.

Application and functionality

The detector finds application in a wide range of industrial and public facilities where there is a risk of ammonia leakage – from refrigeration and food plants to wastewater treatment plants and fertilizer warehouses. Signaling the exceeding of permissible ammonia concentration levels allows for a quick response and minimization of potential threats to health and life. The 4-20mA analog output enables integration with monitoring and automatic control systems for technological processes.

Characteristic features:

• Precise measurement: A catalytic sensor ensures accurate and reliable measurements of ammonia concentration.
• Durable construction: A brass housing with a steel sinter protects the device against mechanical damage and corrosion.
• Safety: Explosion-proof design (flameproof enclosure) allows use in potentially explosive zones (IIA, IIB, IIC).
• Versatility: Compatibility with various control and alarm systems simplifies integration with existing infrastructure.
• Compliance with standards: Meeting the requirements of the ATEX Directive guarantees safe use.
• Calibration: All detectors are calibrated in their own GAZEX Calibration Laboratory accredited in accordance with PN-EN ISO/IEC 17025.
• Modularity: Allows easy sensor replacement, reducing operating costs.

Thanks to its reliability and precision, the DEX-P4K/N gas detector is a key element of the safety system in workplaces where the presence of ammonia may pose a threat.
