Barometric Pressure

Barometric pressure is a measure of the weight of the atmosphere over a particular site. It is measured in hectoPascals (hPa), (or millibars (mB) which are exactly the same thing). Barometric pressure normally varies over a range between 990hPa and 1030hPa.

Barrometric Pressure Sensor

The PTB110 barometric pressure sensors measures the weight of the atmosphere over a particular site. It is measured in hectoPascals (hPa) and normally varies over a range between about 990hPa and 1030hPa. The sensor is normally installed in the data logger enclosure (which is vented to atmosphere). Barometric pressure is useful for forecasting purposes in the Bureau of Meteorology's country-scale recording system. It is of little practical value in weather stations used in agriculture, but is of considerable interest to ground-water scientists as it affects water table measurements. Barometric pressure sensors are commonly found in industrial and research stations, and are particularly useful for calculation of air density in wind energy monitoring systems.
