Gas detector DEX-P4E/N ammonia, 500-1000ppm, P4-C design, electrochemical sensor, brass housing

Gas Detectors – Reliable Protection of the Working Environment

The DEX-P4E/N gas detector is an advanced device designed for continuous monitoring of ammonia concentration in the air. It finds application both in enclosed spaces and in leak detection systems, ensuring safety and health protection. The device is characterized by high measurement accuracy in the range of 500-1000 ppm, allowing for effective detection of even slight exceedances of permissible norms. Explosion-proof construction and a solid brass housing with a steel sinter guarantee reliability and durability even in harsh industrial conditions.

Construction and Application

The DEX-P4E/N detector is part of the DEX/P family of detectors, which utilize an analog 4-20mA current output to cooperate with various control modules and alarm panels. The ability to integrate with MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, MDD-1, MDD-1/T, MDD-1x/T and other control panels accepting a 4-20mA signal (after using the MDPL1 power limiter) provides flexibility and ease of adaptation to existing infrastructure. The device meets the stringent requirements of the ATEX Directive, confirming its safety of use in potentially explosive atmospheres.

The detector finds wide application in:

• Chemical industry – monitoring ammonia concentration during production processes.
• Agriculture – control of ammonia emissions in livestock buildings.
• Food industry – detection of ammonia leaks from refrigeration installations.
• Wastewater treatment plants – monitoring ammonia concentration during biological wastewater treatment processes.
• Warehouses and storage facilities – protection against hazardous ammonia concentrations.

Key Features and Benefits

• High measurement accuracy: Measurement range of 500-1000 ppm ensures accurate detection of ammonia concentration.
• Explosion-proof construction: Use of a flameproof enclosure allows operation in areas at risk of explosion (IIA, IIB, IIC; T1-T6).
• Durable housing: Brass housing with a steel sinter protects the device against mechanical damage and external factors.
• Analog 4-20mA output: Enables easy integration with various control and alarm systems.
• Replaceable electrochemical sensor: Ensures low operating costs and the possibility of quick replacement of a damaged element.
• Compliance with ATEX standard: Guarantees safety and legality of use in potentially explosive areas.
• Calibration in an accredited laboratory: All detectors are calibrated in their own GAZEX Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which ensures the reliability of measurements.

Thanks to these features, the DEX-P4E/N detector is a reliable tool for monitoring ammonia concentration, ensuring the safety of employees and protecting the natural environment. Its modular construction and ease of integration with existing systems make it an optimal solution for both professional installers and end users.
