Pressure sensor It is mainly used in the measurement of acceleration, pressure and force. Piezoelectric acceleration sensor It is a common accelerometer. It has the characteristics of simple structure, small volume, light weight and long service life. Piezoelectric acceleration sensors have been widely used in vibration and shock measurement of aircraft, automobiles, ships, bridges and buildings, especially in aviation and aerospace. The piezoelectric sensor can also be used to measure the internal extinguishing pressure and vacuum degree of the engine. It can also be used in military industry. For example, it can be used to measure the change of bore pressure and the shock wave pressure at the muzzle of a gun when the bullet is fired in the bore. It can be used to measure both large and small pressures.
