Product Description:
MR511 Hot-wire Gas Sensor Is Used To Detect The Concentration Of Combustible Gases Such As Natural Gas liquefied Gas And Gas
Features:
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.
Main application
It can be used to detect the concentration of combustible gases such as natural gas, liquefied gas, and coal gas.
