MR511 Gas Sensor Through The Adsorption Of Gas On The Surface Of Metal Oxide Semiconductor Caused By The Principle Of Thermal And Electrical Conduction Changes To Achieve Detection
Product description:
MR511 gas sensor through the adsorption of gas on the surface of metal oxide semiconductor caused by the principle of thermal and electrical conduction changes to achieve detection, from the sensitive element resistance value change to determine the gas concentration. MR511 consists of a detecting element and compensation element paired in series to form one arm of Wheatstone bridge. When it meets combustible gas, the resistance of the detecting element decreases and the output voltage of the bridge changes. The voltage change increases with the increase of gas concentration, and the compensation element plays a reference and temperature compensation role.
Sensor characteristics:
The MR511 gas sensor has high sensitivity, fast response speed, good repeatability, stable and reliable component operation, and good anti-hydrogen sulfide and silicone interference performance.
Main application:
It can be used to detect the concentration of combustible gases such as natural gas, liquefied gas, and coal gas.
