DEVICE FOR TRANSFERRING PRESSURE WITH ALERTING MEANS ABOUT NEARING DESTRUCTION OF MEMBRANE Russian patent published in 2006 - IPC G01L19/06 G01M3/16 

FIELD: engineering of devices for transferring pressure.

SUBSTANCE: device for transferring pressure acting in first substance, second substance, containing base 1 with pressure chamber 4, which is separated from first substance by means of separating membrane 2, while active pressure can be transferred by means of second substance into pressure measuring cell. For appropriately timed detection of unavoidably nearing damage of separating membrane, advance notification detector contains chamber 6. Mounted in the chamber, indicator 7 continuously controls property of substance present in chamber with indicator. Separating wall 5 positioned on the side of first substance hermetically compacts aperture of chamber and during contact with first substance, being positioned in similar conditions of external effect with separating membrane 2, is destroyed before the separating membrane itself.

EFFECT: possible warning about nearing destruction of membrane.
