In the classification of pressure sensors, it is more common to classify according to the principle of pressure sensors, which can be divided into different types such as piezoresistive, strain gauge, inductive, capacitive, and piezoelectric. Among the pressure sensors with different principles mentioned above, piezoelectric pressure sensors are only suitable for measuring dynamic pressure, so dynamic calibration is required; Static and dynamic pressure of pressure sensors such as piezoresistive, strain gauge, inductive, capacitive and other pressure sensors can be measured, and the most widely used is a quasi-static measurement with very low frequency, so static calibration is the most widely used form of calibration. The calibration of the sensor is to establish the relationship between the input and output of the sensor through experiments, and also to determine the error relationship under different use conditions. The static calibration of pressure sensors mainly refers to the static characteristic indexes obtained through a series of calibration curves, such as nonlinearity, hysteresis, repeatability, accuracy, temperature drift and zero drift. Although the static characteristics of some pressure sensors are very good, they cannot follow the rapid changes of input pressure and make approximate errors, which requires us to carry out dynamic calibration of pressure sensors. The dynamic calibration of the pressure sensor can be described from its rise time, natural frequency, amplitude-frequency characteristics, phase frequency characteristics and other parameters.
