Abstract

A lid to be connected to a housing of a status display for a sensor, with a basic body comprising a covering surface and at least one side wall, wherein the basic body has at least one light-transmissive light emitting region to facilitate an illumination of desired areas of the lid that is homogeneous and space-saving, with a first reflector unit and a second reflector unit arranged opposite each other, and wherein an opening for arranging a lighting means is formed in the second reflector unit, wherein the light emitted by the lighting means is reflected to the at least one light emitting region by means of the first reflector unit and the second reflector unit.

First claim

We claim:

1. A sensor, which is a filling level sensor, a limit level sensor, a pressure sensor, a flow sensor or a temperature sensor, wherein the sensor comprises a status display, with a housing and a light source for displaying a status disposed in the housing, wherein the housing is closed by a lid with a basic body comprising a covering surface and at least one side wall, wherein the basic body has at least one light-transmissive light emitting region, wherein the lid has a first reflector unit and a second reflector unit arranged opposite each other, and wherein an opening for arranging a lighting means is formed in the second reflector unit, wherein the light emitted by the lighting means is reflected via the reflector toward the outside through the at least one light emitting region.

2. The sensor of claim 1 , wherein at least a part of a side wall and/or at least a part of the covering surface of the basic body form a light emitting region.

3. The sensor of claim 1 , wherein the first reflector unit is disposed on the covering surface.

4. The sensor of claim 1 , wherein the reflector unit has a planar configuration, or that the first reflector unit has a convex configuration.

5. The sensor of claim 1 , wherein the first reflector unit is opaque.

6. The sensor of claim 1 , wherein the second reflector unit is a concave mirror.

7. The sensor of claim 1 , wherein the second reflector unit is detachably fastened to the basic body.

8. The sensor of claim 1 , wherein the basic body is at least partially transparent and/or translucent.

9. A lid for a sensor, which is a filling level sensor, a limit level sensor, a pressure sensor, a flow sensor, or a temperature sensor, wherein the sensor comprises a status display, with a housing and a light source for displaying a status disposed in the housing, wherein the housing is closed by the lid and the lid comprises a basic body comprising a covering surface and at least one side wall, wherein the basic body has at least one light-transmissive light emitting region, wherein the lid has a first reflector unit and a second reflector unit arranged opposite each other and wherein an opening for arranging a lighting means is formed in the second reflector unit, wherein the first reflector unit is arranged opposite the opening for the lighting means and the light emitted by the lighting means is reflected to the at least one light emitting region by means of the first reflector unit and the second reflector unit, wherein at least a part of a side wall form a light emitting region.
