Abstract
A pressure sensor for detecting an effective pressure comprises a first pressure detection means for providing a first pressure measurement signal and a second pressure detection means for providing a second pressure measurement signal, wherein the first pressure measurement signal differs from the second pressure measurement signal, as well as an evaluation means for determining the effective pressure based on the first and the second pressure measurement signal. Thereby it is achieved that in a pressure measurement the measurement errors are reduced.
