The pressure sensor will produce some errors during use, sensitivity error, offset error, hysteresis error and linearity error. Calibration eliminates or greatly reduces the impact of errors generated by pressure sensors on test results. The basic method of pressure sensor calibration is to use standard equipment to generate known non-electric power (such as standard force, displacement, pressure, etc.), as an input to the pressure sensor to be calibrated, and then compare the output of the obtained pressure sensor with the input standard quantity, so as to obtain a series of calibration data or curves. The selection of the calibration pressure is very important because it determines the pressure range to obtain the best accuracy. In fact, the actual offset error after calibration is minimal at the calibration point and remains small all the time. Therefore, the calibration point must be selected according to the target pressure range, which may not correspond to the operating range. In order to convert the output voltage to a pressure value, a typical sensitivity is often used for single-point calibration in mathematical models, since the actual sensitivity is often unknown. The static calibration of pressure sensors is mainly used to inspect and test the static characteristics of the sensor, such as static sensitivity, nonlinearity, hysteresis, repeatability, etc. The dynamic calibration of pressure sensors is mainly used to check and test the dynamic characteristics of the sensor, such as dynamic sensitivity, frequency response and natural frequency. To perform dynamic calibration of a pressure sensor, a standard excitation signal needs to be fed into it, and the sine wave in the periodic function and the step wave in the transient function are commonly used.
