Two-level gas detector DG-12/N methane, 10/30% LEL, p-p sensor

Methane detector DG-12/N – reliable safety in industry and homes.

The DG-12/N dual-threshold gas detector is a device designed for continuous monitoring of methane concentration in the air. It finds application both in industrial areas and in residential buildings where there is a risk of leakage of this hazardous gas. This detector is characterized by high sensitivity and reliability, providing effective protection against hazards associated with the presence of methane.

The DG-12/N detector uses a semiconductor gas sensor that reacts to changes in methane concentration in the range of 10-30% LEL (Lower Explosive Limit). It has two independent alarm thresholds, set at the factory, which allows for a quick response when permissible norms are exceeded. The built-in optical signaling informs about the device's operating status and the detection of a dangerous gas concentration.

Construction and principle of operation

The DG-12/N detector is powered by an external system and works with control modules of the type MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8 and MDP-16. Its construction excludes the possibility of use in areas at risk of explosion of gases or dust. The replaceable sensor module facilitates calibration and repairs, and also allows for changing the detector model without having to replace the entire housing. This makes servicing simple and economical. The housing made of high-impact ABS provides resistance to mechanical damage and splash protection (in the recommended mounting position).

Application and benefits

• Methane detection: Precise measurement of methane concentration in the range of 10-30% LEL ensures effective protection against explosion and poisoning.
• Two-stage alarm signaling: Enables a quick response to an increase in gas concentration and minimizes the risk of serious consequences.
• Easy installation and servicing: Modular design and no need for calibration at the installation site greatly simplify the mounting and maintenance process.
• High reliability: Calibration of the detector in its own GAZEX Calibrating Laboratory (PCA accreditation No. AP150) guarantees measurement accuracy and long-term trouble-free operation.
• Versatility: The ability to cooperate with various control modules increases the flexibility of the gas detection system.
• Thermal compensation: Ensures stable readings even under changing temperature conditions.

The DG-12/N detector is an investment in safety that protects both human health and property from the effects of methane leakage. It is an ideal solution for installers of gas detection systems and for owners of industrial facilities and residential buildings requiring reliable monitoring of the presence of this hazardous gas.
