Gas detectors – reliable safety in any environment

The DEX-2E/N gas detector is an advanced device designed for continuous monitoring of carbon monoxide concentration in enclosed spaces. Thanks to the use of an electrochemical sensor, the detector provides precise and reliable measurements, signaling when permissible levels are exceeded. The device is a key element of gas detection systems, guaranteeing the safety of people and property.

Features and application

The DEX-2E/N detector finds wide application in various industrial, commercial and residential facilities where there is a risk of carbon monoxide emissions. It is ideal for:

• boiler rooms,
• garages,
• car workshops,
• industrial kitchens,
• rooms with fuel-burning appliances (stoves, fireplaces).

The detector's design based on the principle of flameproof enclosure allows for its safe use even in potentially explosive atmospheres. This makes it an ideal solution for installers carrying out projects in demanding conditions.

Advantages of the DEX-2E/N detector

• High measurement accuracy: The electrochemical sensor provides accurate and reliable detection of carbon monoxide.
• Alarm signaling: If the permissible gas concentrations are exceeded, the detector immediately activates a visual and audible alarm.
• Explosion-proof design: Ensures safe operation in potentially explosive zones (II 2G).
• Replaceable sensor module: Allows easy replacement of the sensor without the need to replace the entire device, reducing operating costs.
• ATEX compliance: The detector meets the requirements of Directive 2014/34/EU and the Regulation of the Minister of Development, confirming its safety and reliability.
• Modularity and simple installation: Facilitates integration with existing alarm systems and quick installation on site.
• Calibration: Each detector is factory calibrated in its own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees measurement accuracy from the very beginning of use.

Compatibility and integration

The DEX-2E/N detector is compatible with various control modules, such as MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16 and addressable modules of the MDD-1, MDD-1/T and MDD-1x/T type. This allows for easy integration with existing gas monitoring systems and the creation of a comprehensive safety system.

Construction and parameters

The detector housing is made of nickel-plated brass or oxidized aluminum (depending on the version), which ensures high resistance to corrosion and mechanical damage. The device is characterized by compact dimensions (105 x 103 x 54 mm) and low weight (approx. 1.2 kg for the brass housing and approx. 0.5 kg for the aluminum one). The power supply is from an external system (unspecified voltage). The detector has two bistable (threshold) outputs.

Let's remember about the correct installation of the detector – it should be placed in a place that ensures free air flow and is representative of the potential source of carbon monoxide emissions.
