Crankshaft position sensor, also known as the crank angle sensor car level sensor specifications, a computer-controlled ignition system is the most important sensors, whose role is to detect point signal, the crank angle signal and engine speed signal level sensors offer the car stop, and inputs computer, so that the computer can send commands optimum ignition timing by firing order of the cylinder. Crankshaft position sensor, there are three types: electromagnetic pulse crankshaft position sensor, Hall effect crankshaft position sensor, crankshaft position sensor photoelectric effect. Different types of automotive crankshaft position sensor water level sensor control and control accuracy is also different. Crankshaft position sensor is usually installed on the crankshaft pulley or sprocket side, 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. Sensor means able to feel a predetermined physical quantity, according to certain rules to convert the device or devices available input signals. Simply put the car level sensor manufacturers, sensor is converted into electricity to non-power devices. Sensor sensitive element usually consists of the conversion element and the measurement circuit of three parts. 1), sensitive components are those that feel the direct (or response) is measured part of the upcoming conversion is measured by a sensor sensitive components have to be measured to determine the relationship of non-electric or other amount. 2), then the non-electricity conversion element is converted into electrical parameters. 3), the effect of the measurement circuit is to convert the electrical parameters of the input element processed into a voltage, current or power frequency can be measured, for display, recording, control and processing section. Mainly electromagnetic induction type, photoelectric, variable reluctance and Hall concentration. Widespread use of electromagnetic induction type speed sensor and Hall on electric vehicles.
