The potential of force sensors in the automotive industry is huge
Force sensors are sensors used to detect interactions between gases, solids, liquids, and the like. Common materials are semiconductors, metals and synthetic materials. Currently commonly used are silicon piezoresistive force sensors and capacitive force sensors. The advantages of the silicon pressure sensor are that the sensitivity is high, the precision is high, and the disadvantage is that it is greatly affected by temperature.
The force sensor is mainly used in the equipment manufacturing industry, such as industrial automation systems, mechatronics, scientific test instruments, etc. It mainly involves the detection, control and execution of two major parameters of pressure and flow for process control.
Automotive Manufacturing
Automobile engine management system (EMS), which involves real-time and accurate detection and control of various information such as pressure, position, speed, acceleration, etc. EMS can not only accurately control the fuel supply, but also replace the traditional “carburetor”. Controlling the ignition advance angle and total air flow greatly improves engine performance, and 50% pollutant emissions can be reduced by precise control of fuel injection and ignition. The tire pressure monitoring system installs a miniature pressure sensor in each wheel hub to measure the tire pressure, and transmits the information to the monitor in front of the driver through the radio transmitter. When the tire pressure is too low, an automatic alarm is issued, which ensures Drive safely, extend tire life and achieve fuel-saving goals. In particular, the TPWS system for detecting tire pressure is a pioneer in the automotive industry. At present, TPWS replacement for light vehicles is difficult. The TPWS system technology for wireless systems is being developed. The vehicle security system prevents vehicles from being stolen and tilted with a two-axis acceleration sensor. When a theft occurs, the vehicle is lifted up to cause the vehicle to tilt and alarm, and the other is a sensor for the airbag. Hunan Feiersite Sensor Co., Ltd. is a high-tech enterprise engaged in the research and development of sensor products. The company is committed to the development of the world's leading MEMS sensor micro-melting technology, producing differential pressure, pressure, temperature, liquid level, flow and other sensors, widely used. In the automotive industry.
