WHAT IS AIR PRESSURE? Zurück send article to a friend print article


PRESSURE:
in physical sciences, the perpendicular force per unit area.
The SI unit of pressure is Pascal (Pa), Bar (bar) is still legally in use.
1 Pa = 1N/m², 1 bar = 100,000 Pa. Air pressure is generally specified in millibar: 1mbar = 100 Pa = 1 hPa (Hectopascal).

The measurement of air pressure is in many areas an important factor. LAMBRECHT delivers officially calibrated high-quality products. Measuring elements are the carefully aged German silver aneroid capsules.

Pressure measurement is used in classical meteorology. High and low pressure areas significantly determine atmospheric conditions and therefore influence all areas of life and all spheres in nature. Exemplary mentioned shall be aviation and airports, as well as navigation and submarine technology. Statements about air pressure are of high importance in operating and clean rooms, as well as in higher altitudes.
