Automotive sensors - sensors are used to detect gas concentration in vivo gas and car exhaust emissions. Among them, the most important is the oxygen sensor, which detects the vehicle exhaust oxygen content, air-fuel ratio determined according to the oxygen concentration in the exhaust gas, to the computer control means issuing a feedback signal to control the air-fuel ratio converges to the theoretical value. When the air-fuel ratio becomes high, increasing the oxygen concentration in the exhaust gas, the oxygen sensor output voltage decreases; when the air-fuel ratio becomes low, reducing the oxygen concentration in the exhaust gas, the output voltage increases. The electronic control unit recognizes this mutation signal to the fuel injection quantity is corrected, thereby adjusting the air-fuel ratio corresponding wholesale auto level sensor to changes in near stoichiometric. According to market conditions, "the global information company," the survey report, the global light vehicle sensor OEM market with an average annual growth rate of 7.4% in 2010 to reach the size of the car level sensor supply $ 14 billion, and its growth rate far beyond the car itself in average growth rate. In developed countries, automobile water level sensor, along with increasingly sophisticated automotive electronic systems, electronic sensing the rapid development of new technologies, but the growth has matured sensor products will slow down and may even fall; in developing countries, basic automotive sensors are used automobile engines, safety, security, automotive emission control systems level sensor manufacturers, increase the amount of very impressive. Used car curtain developing? King? Troubles Tartar? Sub gluttonous? ü Zha EM production, in order to reduce costs. Automotive sensor suppliers face a serious challenge: on the one hand to expand production capacity, on the other hand you want to continue to reduce costs, this trend is unlikely to change the future. Automobile production level sensor, level sensor Hebi car, Xinfeng Xinfeng sensing provided by Xinxiang purification technology Limited.
