In general, the mechanical vibration sensor receiving principle , only relative or inertia type two, but in the electromechanical conversion , due to the different nature of transformation methods and their variety, extremely wide range of applications . In modern vibration measurement sensors used , is not the traditional concept of separate mechanical measuring device , it is only the entire measurement system in a part of , and with the subsequent electronics are closely related. Since Coolant Temp Sensor different internal electromechanical transformation principle , the output power is also different . Some of the changes in the amount converted into mechanical force , the charge changes , some changes in the mechanical vibration is converted into resistors, inductors and other electrical parameters changes. Generally , the charge and can not be directly subsequent display, recording , analysis instruments accepted . Therefore, electromechanical transformation principle for different sensors must be accompanied by specially equipped measuring circuit . Measuring circuit is the role of Cooling Temp Sensor output power becomes final follow-up show , analytical instruments generally acceptable voltage signal . Therefore, the vibration Position Sensoraccording to their function may have the following classification : according to the principle of mechanical Receive : Relative type, inertial ;
According to the principle of electromechanical conversion : electric , piezoelectric , eddy current , inductive , capacitive, resistive, photoelectric ; measured by the amount of machinery : displacement sensor, speed sensor
Crank position sensor is usually installed in the distributor, the control system is the most important one of the sensors. Its role is: detecting the engine speed, so-called rotation speed sensor; detects the piston top dead center position, it is also known as the only point sensor, including the detection of each cylinder for controlling the ignition TDC signal for controlling sequential spray oil first cylinder TDC signal
