Sensor is a detection device that will convert the input variable for the measured signal is optoelectronic systems " sense organs " , is to achieve automatic detection and automatic control of the primary link . Sensor is a huge market, in 2008 the global sensor market capacity of 50.6 billion U.S. dollars , the global sensor market is expected in 2010 up to 600 billion U.S. dollars. On a global scale Crankshaft Position Sensor market is still the fastest-growing car market , is the second largest market, process control , communications, market prospects. A wide variety of Crankshaft Sensor , according to incomplete statistics , there are 30,000 kinds , pressure sensors , temperature sensors , flow sensors, level sensors have demonstrated the characteristics of a mature market , flow sensors, pressure sensors, temperature sensors largest market , respectively, accounted for the entire sensor market for 21 %, 19% and 14%. Sensor market, the main growth came from the wireless sensor , MEMS ( microelectromechanical systems ) sensors , biosensors and other emerging sensors.
Camshaft position sensor, also known as the cylinder identification sensor, camshaft position sensors are generally expressed by CIS. Camshaft position sensor function is to collect the valve camshaft position signal, and input ECU, in order to identify the ECU compression TDC cylinder 1, thereby performing sequential fuel injection control, ignition timing control and knock control.
