Abstract: The invention concerns a capacitive level probe, in particular for measuring the filling height of a liquid medium, comprising a connection portion (14), an electrode (12) which is connected to the connection portion (14) and which projects beyond the connection portion (14) and which includes a sensor element (28), an insulating sleeve (16) which radially completely surrounds the sensor element (28), wherein the insulating sleeve (16) bears against the electrode (12) in a contact region (30), and wherein the electrode (12) and the insulating sleeve (16) are so designed that gas (56) present in the contact region (30) flows out of the contact region (30) on a flow path (51) out of the contact region (30) upon a pressure drop between the contact region (30) and the area surrounding the level probe (10).
