Abstract
This paper mainly introduces the calibration method of piezoelectricity pressure sensors in the pressure field testing. The sensor used in the testing is made of piezoelectricity crystal and it can directly transform the pressure signal into electricity signal. Its output is in proportion to the measured pressure. This kind of sensor has the virtue of large testing pressure range, good linearity, rapid respond, high pressure-electricity sensitivity and less geometrical size. In this paper the calibration method of piezoelectricity pressure sensor is given in the laboratory and in the open-field respectively and is studied contrastively.
