Abstract
Pressure measuring instrument, comprising a mounting plate and a flexible separating element which is disposed in an opening of the mounting plate and fastened thereto, and which separating element is under the action of a measured pressure during the pressure measurement. In order to compensate errors of the pressure measurement due to accelerations, the pressure measuring instrument further comprises a reference body which is connected to said mounting plate via a suspension and comprises a reference surface facing a surface of said separating element, the reference body and the suspension being so designed that when the entire pressure measuring instrument is subject to an acceleration, the resulting displacement of the reference surface of said reference body is equal to the displacement of the surface of said separating element on account of the acceleration.
