FIELD: measurement technology. SUBSTANCE: membrane 2 is secured in sensor body 1. It divides body into two spaces: overmembrane 6 and undermembrane 4 spaces coupled to delivery capillary channels. Spaces 6 and 4 and capillary channels are filled with buffer liquid, which allows undistorted transmission of measured medium pressure to sensor membrane 2 without losses. EFFECT: higher measurement results. 2 cl, 5 dwg
