Methane gas detector

The DN-K3000 Combustible Gas Alarm Controller is a functional and easy-to-operate combustible gas alarm controller. It can be paired with our company's DN-T3000A and DN-T3000AS series point-type combustible gas detectors to form an industrial combustible gas alarm system.
The design, manufacture, and inspection of this product comply with the following national standards:
GB16808-2008 "Combustible Gas Alarm Controller"
The gasoline alarm control system consists of a (gasoline detection alarm controller) connected with (natural gas detection alarm detectors) to form a gasoline detection alarm control system device. Installation and networking are convenient, allowing for centralized control of 1-4 monitoring points simultaneously. Each channel features automatic display, LCD backlight, automatic channel inspection, and locking settings. When the concentration of natural gas in the environment reaches or exceeds the pre-set alarm value, the alarm immediately triggers an audible and visual alarm to alert the user to take safety measures. It also drives exhaust and shut-off systems, effectively preventing the occurrence of safety accidents, thereby ensuring safe production and preventing property loss. The monitoring environment for each detector is 8-15 square meters. Users can choose different specifications based on the area of the monitored environment. If the user's needs exceed capacity, multiple units can be used in tandem, or the DN-K4000 or DN-K2000 multi-channel models can be selected. This product is suitable for places where gasoline is used or stored. The product is also widely used in hazardous places containing combustible and toxic gases in industries such as metallurgy, gas stations (rooms), petroleum, petrochemicals, chemical industry, light industry, coking, steel plants, gas stations, CNG stations, food processing plants, cold storage, hotels (kitchens), municipal engineering, coal gas, pharmaceuticals, fire protection, workshops, as well as sewage treatment and many other special industries and fields.
Product Features:
1 LCD screen with full Chinese menu operation, capable of displaying detector concentration and status in real-time;
2 Branch communication with automatic protection function, strong anti-interference capability, economical wiring, and convenient installation;
3 Automatic fault detection, capable of accurately indicating fault location and type;
4 Automatic retrieval of detector types and alarm points, achieving monitoring of %LEL / ppm / %vol multi-type detectors on the same system without the need for settings;
5 Built-in large-capacity data storage, capable of recording 999 alarm messages, 100 power-on time messages, and power-off time messages; information is not lost during power failure;
6 Built-in 3 sets of relay contact signal outputs: one set of normally open/closed, one set of pulse normally open/closed, capable of linkage control of exhaust fans or solenoid valves. Linkage signals can be output manually or automatically;
7 RS485 bus communication interface (optional, standard Modbus/RTU protocol), capable of networking with upper computer control systems to achieve remote monitoring, greatly improving the timeliness and accuracy of monitoring.
