A pressure sensor is a sensor that can sense and measure the pressure of a gas or liquid, which converts the pressure signal into an electrical signal that can be processed and transmitted. In the industrial, automotive, aerospace, medical and other fields, pressure sensors play a vital role. It can monitor and feedback pressure changes in real time, helping the system achieve accurate control and safe operation. With the continuous progress of technology, the accuracy, stability and reliability of pressure sensors are also improving, and they can adapt to a variety of complex environments and application scenarios.
