Abstract

A protective device for sealing a sensor device of an intermediate area outside a sensor device attached to a container, a measuring device, a container with a fastening device for fastening a protective device and the use of a protective device for sealing a sensor device of an intermediate area outside a sensor device attached to a container, in particular a level radar sensor arrangement. The protective device comprises a housing and a circumferential seal arranged on a side of the housing intended for abutment against the container or on an outer side of the housing.

Claims (10)

1 . A protective device for receiving a sensor device, the protective device being attached to a container and comprising:

a housing comprising an outside thread;

a mounting device fixedly mounted to the container and comprising an inside thread into which the outside thread of the housing is screwed to fasten the protective device to the mounting device; and

a perimeter seal disposed on an outer conical surface area of the housing adjacent to the outside thread and between the housing and the mounting device and pressed against a corresponding conical surface area of the mounting device to provide sealing of a cavity formed by the housing, the container, the seal and the mounting device.

2 . The protective device according to claim 1 ,

wherein the perimeter seal is configured to be deformable.

3 . The protective device according to claim 1 ,

wherein the mounting device is configured to generate a compressive force on the perimeter seal when the protective device is fastened to the container to press the perimeter seal against the container or against the mounting device.

4 . The protective device according to claim 1 ,

wherein the perimeter seal is configured to be deformable.
