Patent ID: 7546774

Claim:
An acceleration-compensated pressure pick-up, for example for the measurement of dynamic processes in gaseous or liquid media, comprising: an external housing as well as a pre-assembled inner part having a flange at its assembly end wherein the inner part is securely fixed to the housing only at the flange, a first resilient connection, a first mass connected via said first resilient connection to said flange, a second resilient connection, a second mass connected via said second resilient connection to said flange, a first measurement crystal inserted under pre-tension between said masses, a third mass and a compensation crystal arranged between said first measurement crystal and said second mass, wherein the compensation crystal is electrically connected in opposition to the first measurement crystal, and the two rigidities of the resilient connections as well as the three masses are matched so that the measurement values which can be determined at the crystals due to an axial acceleration acting on the housing compensate each other.
