Five Applications of Pressure Sensors in Automobile Industry

In modern automobile industry, the application of pressure sensor is increasingly extensive, and it has become one of the important technologies to improve automobile performance, safety and fuel economy. These small but powerful devices are widely used in various systems to ensure the efficient operation and driving safety of vehicles. without

Whether in engine management, braking system or tire monitoring, pressure sensor plays a vital role. In the engine management system, the pressure sensor is an indispensable component. For example, the oil pressure sensor is responsible for monitoring the oil pressure in the engine to ensure that all moving parts are properly lubricated. If the oil pressure is lower than the set value, the sensor will immediately send a signal to the engine control unit, triggering the warning light on the dashboard to remind the driver to take timely measures to avoid engine damage caused by insufficient oil. The intake pressure sensor monitors the pressure change in the intake manifold and provides accurate intake information for the engine control unit, so as to optimize fuel injection and air-fuel ratio, improve fuel economy and reduce exhaust emissions.

In the braking system, the pressure sensor is also a key role. They monitor the pressure and hidden parts of the brake fluid in real time to ensure the efficient operation of the braking system. By using the pressure sensor, ARS (Universal Locking System) and DSC (Dynamic Stability Control System), the braking force can be well regulated, and the braking performance and vehicle stability can be improved. When there is air leakage in the brake booster system, the pressure sensor will immediately give an alarm and start the corresponding warning system to avoid potential safety hazards. Tire pressure monitoring system (TPMS) is also a major application of pressure sensors. Modern cars are generally equipped with this system, which can automatically raise the indicator light on the dashboard and easily show the specific pressure teaching value when the tire pressure is lower than the set value, which greatly reduces the tire pressure.

The probability of frequent traffic accidents. In addition to the above main application fields, pressure sensors are also used in air conditioning systems, fuel supply systems and battery management systems. For example, air conditioning pressure sensors monitor the pressure of refrigerants, prevent abnormal pressure from damaging the compressor, and ensure the comfort and control of the temperature inside the car. Stability of cold system. The fuel pressure sensor detects the pressure change in the fuel supply system in real time to ensure the fuel supply is stable, thus improving the combustion efficiency. With the popularization of new energy vehicles, the application of pressure sensors in the battery management system has attracted more and more attention. By monitoring the pressure change inside the battery pack, Rolex sensors can detect the hidden electricity such as overheating or short circuit of the battery in time to ensure the safe operation of new energy vehicles. The application of pressure sensor in automobile industry not only improves the performance and safety of vehicles, but also promotes the development of automobile intelligence. In the future, with the continuous progress of technology, pressure sensors will play a greater role in more fields and bring new breakthroughs in driving experience and driving safety.
