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

Environmental control in the subway system piping temperature and humidity sensors
In the meantime, we can at the station's new air chamber and the return air duct temperature and humidity chamber mounted sensors to monitor the outdoor air and the temperature and humidity inside the station. Environmental control system according to the data collected byCar Temperature Sensor to determine the environmental quality of the station, and according to a variety of conditions pre-designed for automatic switch, automatic control system in order to achieve automatic control of the environment of the station, so that the station is always in a more environment comfortable environment, and ultimately achieve the purpose of energy saving and emission reduction. Pipeline temperature and Coolant Temperature Sensor is usually installed in the new and the return air plenum chamber walls. Thus, the temperature and humidity sensor usefulness in life more and more, it is not only in the station, greenhouse, file management and food industry has applied, is now in the subway environmental control system has also been adopted.
