Method and device for verification and/or calibration of a pressure sensor

摘要

The invention relates to a method for carrying out a calibration test on a pressure sensor comprising the steps:
- fluidly connecting the pressure sensor to a first fluid storage vessel;
- fluidly connecting the pressure sensor to a second fluid storage vessel;
- providing an initial fluid pressure p 0 at the pressure sensor, the first fluid storage vessel and the second fluid storage vessel;
- carrying out a pressure measurement of the initial fluid pressure p 0 at a time to by means of the pressure sensor;
- fluidly disconnecting the second fluid storage vessel from the pressure sensor and the first fluid storage vessel;
- providing a first fluid pressure p 1 at the second fluid storage vessel;
- carrying out a pressure measurement of the first fluid pressure p 1 at a time t 1 by means of the pressure sensor;
- fluidly connecting the second fluid storage vessel with the pressure sensor and the first fluid storage vessel, so that a second fluid pressure p 2 is provided at the pressure sensor, wherein the second fluid pressure is between the initial fluid pressure p 0 and the first fluid pressure p 1 ;
- carrying out a pressure measurement of the second fluid pressure p 2 at a time t 2 by means of the pressure sensor and
a corresponding test device and a computer program product.
