In the industrial field, pressure sensors are widely used in various equipment and systems. For example, in hydraulic systems, air pressure systems, refrigeration systems, etc., pressure sensors can monitor pressure changes in real time to ensure the normal operation of the system. In the automotive field, pressure sensors are also used in engines, brake systems, tires and other components to ensure the safety and performance of the car. In addition, in the aerospace field, pressure sensors also play an important role in monitoring air pressure and altitude changes in aircraft, rockets and other aircraft.
