Digital Barometers

leaflets:    DB-X in version DB-1, DB-2 and DB-3

                  DB278 D Digital Barometer

No. DB-1, DB-2 and DB-3     SERIES OF DIGITAL BAROMETER DB-X           

The application range of the serie DB-X are the measurements of pressure in meteorological stations, aviation use and in laboratories. Depending on the technical requirements and of the needed redundancy the user can select the specific model of DB-X, namely DB-1 with one, DB-2 with two or DB-3 with three independent working pressure transducers. The economical Barometer type DB-1 meets the most applications e.g. in the field of meteorology. For requirements of higher and highest accuracy with large reliability and redundancy the user should select DB-2 or DB-3 with two respective three combined pressure capsules.

The used barometric pressure sensor is designed for measurements that require excellent accuracy, fast dynamic response and long-term stability and reliability.
