Embodiment Construction

[0028] Figures 1 to 3 An exemplary fill level measuring device or at least individual components of such a fill level measuring device for determining and / or monitoring a fill level, in particular in a container, are shown in different views.

[0029] Such a level measuring device consists in a manner known per se of a diaphragm 1 which can be fastened in a housing by means of its diaphragm rim 2 . The diaphragm 1 is surrounded here by a rigid diaphragm rim 2 , but at the same time the diaphragm 1 remains vibrateable. Diaphragm 1 has a vibrating body, for example in the form of a fork 3, towards the front, which serves as an antenna for transmitting vibrations of the diaphragm 1 to the surroundings of the front and simultaneously as a receiver of vibrations from the surroundings of the front for sending vibrations to the surroundings of the front. Diaphragm 1 passes. Arranged toward the rear of the membrane 1 is a drive 4 which clamps against the membrane 1 with a front drive...

Abstract

The invention relates to a fill-measuring device for determining and / or monitoring the fill level of a container, said device being comprised of: a membrane (1) which can be caused to vibrate; a rigid membrane rim (2) in which the membrane (1) is disposed; a drive device (4) having a drive end face (5) to impel the membrane (1) into vibration, and / or to convert vibrations of the membrane (1) into an electrical signal; and an attaching device (13) for attaching the drive device (4) to the membrane rim (2); wherewith, according to the invention: a part of the attaching device (13) is disposed in a region extending between the membrane (1) and the drive end face (5) of the drive device (4); and at least one pressure transmission element (6) is disposed between the membrane (1) and the drive end face (5) of the drive device (4), in a manner such that the membrane (1) and the drive end face (5) are coupled together for purposes of transmission of vibration.

Description

technical field [0001] The invention relates to a liquid level measuring device having the features according to the preamble of claim 1 for determining and / or monitoring a liquid level in a container. Background technique [0002] Fill level measuring devices are known in a wide variety of embodiments for determining and / or monitoring a fill level in a line or container. In particular, there are liquid level measuring devices which comprise a diaphragm which can be oscillated, which is arranged in a rigid diaphragm rim. The diaphragm rim can also be an integral part of a housing or be fixedly connected to the housing of a level measuring device. Usually such level measuring devices have a drive for oscillating the diaphragm with a drive end face of the drive and / or for receiving vibrations of the diaphragm and converting them into an electrical signal. In order to be able to achieve this, such level measuring devices are usually provided with a fastening device for fasten...
