UNIT OF PROTECTION OF SEPARATING MEMBRANE OF PRESSURE SENSOR AGAINST PRESSURE OVERLOAD

摘要

FIELD: measurement equipment.SUBSTANCE: unit of a separating membrane comprises a body, on which a separating corrugated membrane is attached in a non-detachable manner along the periphery. Corrugations of the separating membrane correspond to corrugations on the body under it and form a working gap with the body, filled with the separating non-compressible liquid. The working gap is connected with the cavity of the sensor with the help of two holes on the edge corrugation. On the corrugated surface of the body there are two radial grooves that connect the gap under the central area of the membrane with holes that connect the working gap with the sensor cavity.EFFECT: provision of protection of a corrugated separating membrane of a pressure sensor against overload in case of quick pressure variation.3 dwg
