Oxygen sensor is the use of ceramic sensor components measured in the exhaust gas pipeline electrical potential, calculated by the chemical balance of the corresponding oxygen concentration, to monitor and control the combustion air-fuel ratio to ensure product quality and exhaust emissions of the measurement components. It has the advantages of simple structure, rapid response, easy maintenance, easy to use and accurate measurement. The use of the sensor for combustion measurement and control can both stabilize and improve product quality, but also shorten the production cycle, saving energy.
