Crankshaft position sensor, also known as crank angle sensor, a computer-controlled ignition system is the most important sensor automotive sensor production, its role is to detect point signal, the crank angle signal and engine speed signal only, and entered into the computer so that the computer optimum ignition timing command can be issued by the cylinder firing order. Crankshaft position sensor, there are three types: electromagnetic pulse crankshaft position sensor, Hall effect crankshaft position sensor, crankshaft position sensor photoelectric effect. Crankshaft position sensor type is different, its control and control accuracy is also different. Crankshaft position sensor is usually installed on the side of the crankshaft pulley or sprocket automotive sensors, some mounted on the front end of the camshaft, and some are mounted on the distributor. Knock sensor mounted on the engine block, ready to monitor the engine's knock. Using resonant and non-resonant two categories. Approximation test content in the actual production of automotive sensors which, the test also has some different sensors approximation. Because the test principle, automotive sensors are divided into active / passive, temperature, pressure, and other types of sensors. That is, for different sensors, the principle is the same as long as the test vehicle sensors offer, it means that their test equipment and other equipment is the same. Efficient and flexible production line test equipment automotive sensors require the use of economic, efficient, automated, flexible test equipment, but also to have a high degree of automation, high efficiency, high performance, high reliability. Disposable sensor manufacturers hope into the future, the test equipment itself can be expanded continuously and effectively support the latest products and higher performance requirements to ensure the effectiveness of capital equipment investment.
