BAROSENSITIVE ELEMENT Russian patent published in 1998 - IPC

FIELD: instrumentation engineering. SUBSTANCE: barosensitive element is reliable in operation at high pressure due to removal of bending moment arising when operating surface of membrane and cover is loaded. Barosensitive element has membrane 3 with piezoelectric element 4 fixed to cover 1 through gasket 2 which has hole of diameter d which forms airtight cavity and presets operating surface of membrane. Hole diameter d of gasket 2 is selected from condition d/2≤l, where l is minimum linear size of place where membrane 3 is coupled to gasket 2. EFFECT: higher reliability. 1 dwg
