Summary:In this paper, a static pressure calibration device is designed and the method of static calibration with piezoelectric pressure sensors is discussed. According to the theory of PASCAL law, the static calibration device is developed, whose stress ratio is up to 1:25. And this device has been accredited by the authorities. To ensure the consistency of pressure calibration, the improvements on calibration device’s output are made. As a result, we can calibrate up to four sensors at the same time. By means of the pressure calibration device, the calibration method of pressure sensor, the calibration theory, system components and calibration procedures is given. As the test results shown, the corresponding sensors’ static calibration linearity is 0.05%, and its uncertainty is 0.42%. It’s practicable and reliable to make static calibration to sensors by the pressure calibration device.
