QB2000FWall mounted hydrogen sulfide detector
QB2000FWall mounted hydrogen sulfide detectorIt is a fixed instrument that can continuously detect the concentration of flammable gases, oxygen, or toxic or harmful gases in the working environment. Suitable for situations where combustible gas, oxygen, or toxic and harmful gases may leak in power, electronics, metallurgy, chemical, petroleum, coal, mining, railway, and medicine industries.
QB2000FTo detect gas concentration through free diffusion, imported electrochemical sensors or catalytic combustion sensors are used, which have excellent sensitivity and repeatability; The large LCD screen displays the concentration value of leaked gas in real time. If it exceeds the preset alarm point, the sound and light alarm signal will be immediately activated or the exhaust system will be driven; The standard (4~20) mA signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with a simple Chinese menu operation, complete functions, high reliability, and reliable overall performance.
Product Introduction QB2000FAccording to the application scenario, it can be divided into two types: explosion-proof and non explosion-proof. Explosion proof type: The whole machine has undergone explosion-proof treatment and has reached the Exd Ⅱ CT6 Gb level. It can be directly connected to explosion-proof winding pipes and installed in places with explosive gases and vapors. Non explosion proof type: It is prohibited to install it in places with explosive hazards. The lead wire should be connected using a plug, gasket, and rubber sleeve.
128 * 64 dot matrix ultra large LCD display with infrared remote control function
Users can set high and low alarm points with a fully Chinese menu for convenient use by domestic users
*Alarm time display function with real-time clock function
The replaceable modular sensor password management function separates user and manufacturer system operations, allowing for effective querying of operation records
Alarm record and operation record query function standard (4~20) mA signal can be directly connected to the factory DCS system RS485 digital signal and connected to the factory upper computer (user optional)
Hydrogen sulfide is a strong neurotoxin that has a strong irritant effect on mucous membranes.
Hydrogen sulfide is rarely used in industrial production and is mostly a byproduct of chemical processes. As a product of certain chemical reactions and natural protein decomposition processes, as well as a component and impurity of certain natural substances, it often exists in various production processes and in nature. Such as mining and non-ferrous metal smelting. Low temperature coking of coal, extraction and refining of sulfur-containing petroleum, rubber, leather, dye, sugar and other industries all produce hydrogen sulfide. Excavation and remediation of swamps, ditches, printing and dyeing, sewers, tunnels, as well as removal of garbage, feces, and other operations. In addition, hydrogen sulfide is often present in natural gas, volcanic jets, and mineral springs.
