FIELD: fastening devices.
SUBSTANCE: invention relates to devices for attachment of objects to smooth support surfaces. Summary: device comprises rigid body (3) made in the form of an inverted cup with integral bottom (7). At the base of rigid body (3) there is a concentric face groove (8), in which there is sealing ring (5). O-ring (5) protrudes from rigid body (3) and projecting surface repeats shape of smooth bearing surface (2). Sidewall of rigid body (3) has through threaded hole (4) to accommodate union (6) with check valve for air suction. At that, rigid body (3) is made with possibility of contact with smooth bearing surface (2), and sensor (1) is installed outside of bottom (7).
EFFECT: technical result is reduction of overall dimensions of device, higher reliability of its operation.
