Automotive pressure sensors are used for oil pressure control of brake systems with oil pressure booster devices, which can detect the pressure of the reservoir, the closure or disconnection signal of the output oil pump and the abnormal oil pressure alarm.
Automotive industry on the sensor requirements are extremely demanding, automotive pressure sensors must have high stability and accuracy, fast response, good reliability, anti-interference and seismic ability, long service life and so on.

Automotive pressure sensors are mainly used to detect the pressure of brake hydraulic system and lubricating oil system, manifold pressure, wind pressure, atmospheric pressure and tire pressure sensors to measure the pressure of gas medium. At present, there are mainly capacitive, piezoresistive and differential pressure sensors used in vehicles Dynamic transformer type (IVDT) and surface elastic wave type (SAW).

With the continuous progress of science and technology and the rapid development of industry, pressure sensors are facing unprecedented development opportunities. On the one hand, with the continuous emergence of new materials and new processes, the performance of pressure sensors will be further improved, such as higher accuracy, lower power consumption, stronger anti-interference ability; On the other hand, with the popularization and application of technologies such as the Internet of Things and big data, pressure sensors will be interconnected with more devices to form a more intelligent and efficient measurement system. In addition, with the continuous improvement of environmental awareness and the optimization and adjustment of the energy structure, the application of pressure sensors in clean energy, environmental monitoring and other fields will continue to expand and deepen. In short, pressure sensors as an important part of modern industry, its future development prospects are very broad.
