  • Measurement device for measuring of air pressure, particularly for recording air data in aircraft
    Patent number: 4724707
    Abstract: The invention refers to a measurement device for measuring air pressure by means of a pressure sensor that can be excited to natural oscillations. In order to eliminate the influence of relative humidity on the air pressure to be measured, it is suggested that a humidity sensor be used, preferably in the form of a condensor with a humidity sensitive polymer as a dielectric, and that the identified pressure values be corrected for the influence of the humidity.
