Automotive Sensor - Vehicle Speed ??Sensor is used to measure the speed of electric cars. Vehicle speed sensor signal is mainly used for the dashboard speedometer display and the engine idling, the electric vehicle acceleration during the control. At present, the vast majority of China's electric car speedometer on a car forum is transformed into a selected speed speed speed of the car. This is in the case of automobile brakes, skidding, and the forum due to old and new, friction, road, tire pressure, etc., causing the outer circumference of the level of change will cause the error is too large, or even unable to work, the speed sensing sensor characteristics of automotive sensors - Temperature sensors are used to detect the engine temperature, suction gas temperature, cooling water temperature, fuel temperature, and the catalytic temperature. Temperature sensors have wound resistance, thermal resistance and thermal resistance even three main types. Three types of sensors have their own characteristics, its applications are also slightly different. High wirewound resistive temperature sensor accuracy, but the response is poor; thermistor temperature sensors offer high sensitivity auto level sensor, the response characteristics of a good, but poor linearity auto level sensor adaptation lower temperatures; thermocouple temperature resistance high precision sensors, measuring a wide temperature range of high quality auto level sensor, but the need to meet the amplifier and the cold side handle together. Products have been practical thermistor temperature sensor (Universal -50 ℃ ~ 130 ℃, 1.5% accuracy level sensor automobile manufacturers, the response time 10ms; High temperature 600 ℃ ~ 1000 ℃, 5% accuracy, response time 10ms) , ferrite type temperature sensor (ON / OFF type, -40 ℃ ~ 120 ℃, precision 2.0%), metal or semiconductor film air temperature sensor (-40 ℃ ~ 150 ℃, precision 2.0%, 5%, the response time 20ms) and so on.
