Barometric or atmospheric pressure is used to determine a pressure system and therefore often part of an Automatic Weather Station (AWS). A measurement range of 800,1100 hPa is commonly used in order to gain the highest accuracy.

Observator Instruments can supply barometric pressure sensors with a lower range, down to 600 hPa. In order to reduce the wind effects, the pressure sensor can be connected to a so-called pressure port in case ventilation to the outside air is necessary.
