Gas detector DEX-41/N ammonia, 500/1500 ppm, p-p sensor, F4-C design, brass housing

Gas detectors – reliable safety in every installation

The DEX-41/N gas detector is an advanced device designed for continuous monitoring of ammonia concentration in the air. Equipped with a semiconductor sensor with a measurement range of 500/1500 ppm, it provides effective protection against hazards associated with the presence of this gas. Explosion-proof construction and a solid brass housing guarantee reliable operation even in harsh industrial conditions. The detector signals exceeding two alarm thresholds, allowing for a quick response in the event of a failure or dangerous increase in ammonia concentration.

Application and functionality

DEX-41/N finds application in a wide range of facilities, such as chemical plants, sewage treatment plants, fertilizer warehouses, as well as in ventilation and air conditioning systems. The device is compatible with various GAZEX control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16 and MDD-1, MDD-1/T, MDD-1x/T), which allows integration with existing alarm and process control systems. The detector meets stringent ATEX standards, confirming its safety and suitability for use in potentially explosive areas.

Construction and product features

The DEX-41/N detector is characterized by a solid construction ensuring long-term and trouble-free operation. The brass housing protects the internal components from mechanical damage and external factors. A replaceable sensor module facilitates servicing and calibration of the device. F4-C execution provides high resistance to corrosion and aggressive environment. The device is designed to operate in zones 1 or 2 hazardous with explosive gases or vapors (explosion group IIA, IIB or IIC).

• High sensitivity: The semiconductor sensor provides a precise measurement of ammonia concentration over a wide range.

• Durable construction: The brass housing protects the device from mechanical damage and corrosion.

• ATEX compliance: Guarantee of safe use in potentially explosive areas.

• Easy integration: Compatibility with GAZEX control modules facilitates connection to existing alarm systems.

• Replaceable sensor: Allows for quick replacement and calibration of the device without the need to disassemble the entire housing.

• Two-stage alarm: Signaling of exceeding two alarm thresholds (A1 and A2) for increased safety.

• Wide range of applications: Ideal for monitoring ammonia concentration in various industrial and public utility facilities.

Thanks to these features, the DEX-41/N detector is a reliable solution for ensuring safety in workplaces and protecting human health from the harmful effects of ammonia.
