FIELD: measuring equipment.
SUBSTANCE: invention relates to a class of measuring instruments; it can be used in the development and manufacture of absolute pressure sensor with high metrological and operational characteristics. The device includes fitting (1), perceiving element (3) made in the form of bellows, connected to fitting (1) from one side and to plug (4) from the other side, rod (5) connecting plug (4), sensitive element (6), and elastic element (7) made in the form of membrane, case (2) connecting fitting (1) and elastic element (7), and under-pressure chamber (8) connected to elastic element (7). At the same time, it has three cavities: perceiving one limited with fitting (1), perceiving element (3), and plug (4), middle one limited with fitting (1), perceiving element (3), plug (4), case (2), and elastic element (7), and reference one limited with elastic element (7) and under-pressure chamber (8), in which under-pressure is created through open union (9).
EFFECT: increase in the accuracy of measurements and a service life of a sensor.
