Gas detector DG-14/N methane (selective), 10/30% LEL, p-p sensor

Methane detector – reliable protection for your installation

This gas detector is designed to detect methane in industrial and enclosed spaces. The device signals the presence of dangerous gas concentrations, protecting against potential hazards. It is a key element of the safety system, both for installers responsible for the proper functioning of gas installations, and for end-users who care about health and property protection.

The DG-14/N detector is characterized by selectivity in detecting methane in the range of 10/30% LEL (Lower Explosive Limit). It uses a semiconductor sensor (p-p) which provides a precise measurement and a quick response to changes in gas concentration. A replaceable sensor module with two alarm thresholds facilitates maintenance and calibration of the device, and also allows it to be adapted to specific application needs.

Functionality and design for professionals and users

The DG-14/N detector is designed to work 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 and MDP-16. The detector's design is simple and does not require calibration on-site – which significantly speeds up and simplifies the installation process. A splash-proof ABS housing (IP44) provides resistance to environmental conditions.

It is important to remember that this detector has a conventional construction and cannot be used in areas at risk of explosion of gases, vapors or dusts. This is an important limitation that must be taken into account when choosing a device for a specific application. The interchangeability of sensor modules is not only convenient – it allows for quick replacement of a damaged sensor or a change of detector model without having to replace the entire device. The interchangeability of modules with a semiconductor and electrochemical sensor further increases the flexibility of use.

• Replaceable sensor module: Allows for easy calibration or repair and changing the detector model.
• Optical signaling: Informs about the detector's operating status.
• Splash-proof housing: Provides protection against moisture (IP44).
• Modularity: Simplified installation and gas detection system design.
• Accreditation: Detectors are calibrated in their own GAZEX Calibrating Laboratory (PCA accreditation no. AP150), which guarantees measurement accuracy.

Technical specifications and application

The DG-14/N detector has two bistable (threshold) outputs and a built-in optical signal. Power is supplied from an external system. Its compact dimensions (110 x 140 x 55 mm) allow for easy installation in various locations. The device is particularly useful in boiler rooms and other rooms where there is a risk of methane leakage. Thanks to its precision and reliability, it is an integral part of safety systems in residential, industrial and commercial buildings.
