Device for level-checking in a container with a vibration structure which consists of two vibration elements which are arranged concentrically and at least partially surrounding one another, the vibration of which structure is damped in the event of contact of filling material, as a result of which an indication is triggered. In order to simplify the construction of devices of this type known so far and to make manufacture more economical, the outer vibration element is according to the invention designed as a rotary vibrator and the inner vibration element as a bending vibrator, the inner vibration element consisting of a simple bar.
