Abstract

The present disclosure relates to a measuring system including: an automation field device embodied for determining and/or monitoring a process variable of a medium; a connection unit, which includes a connection plug, which is electrically connected with the field device, and a cable, which is connected to the connection plug with a cable connection and which serves for supplying the field device with electrical energy and/or for transmitting information between the field device and a superordinated unit; and a protective cover, which surrounds the connection unit and the field device connected with the connection unit in a protection section, wherein by means of the protective cover the impact resistance of the measuring system in the protection section is increased.

First claim

The invention claimed is:

1. A measuring system, comprising:
an automation field device configured for determining and/or monitoring a process variable of a medium;
a connection unit including a connection plug and a cable connected to the connection plug with a cable connection, the connection plug electrically connected with the field device, wherein the cable is adapted to supply the field device with electrical energy and/or to transmit information between the field device and a superordinated unit; and
a protective cover surrounding the connection unit and the field device connected with the connection unit in a protection region, wherein the protective cover is structured to increase the impact resistance of the measuring system in the protection region.

2. The measuring system of claim 1 , wherein the connection plug is connected with the field device in a connection region, the connection region opposite a process connection of the field device.

3. The measuring system of claim 2 , wherein the protection region extends at least from the connection region to the cable connection.

4. The measuring system of claim 2 , wherein the protection region extends over an area larger than a region bounded by the connection region and the cable connection.

5. The measuring system of claim 2 , wherein the protective cover includes a window via which at least the display unit is visible.

6. The measuring system of claim 2 , wherein the protective cover includes a transparent section at least in the region of the display unit.

7. The measuring system of claim 1 , wherein connection plug is electrically connected with the field device by pushing the connection plug onto connection pins of the field device.

8. The measuring system of claim 1 , wherein the protective cover is configured as to be releasable from the measuring system.

9. The measuring system of claim 1 , wherein the protective cover includes at least two parts configured to be mechanically connectable with one another.

10. The measuring system of claim 1 , wherein the protective cover is a single piece.

11. The measuring system of claim 1 , wherein the protective cover is configured to be screwed onto or into the field device via a complementary screw thread of the field device disposed at an end region of the protection region.

12. The measuring system of claim 1 , wherein the protective cover is made of a metal.

13. The measuring system of claim 1 , wherein the protective cover is made of a synthetic material.

14. The measuring system of claim 1 , wherein the field device includes a display unit configured to display of status information and/or the process variable, the display unit disposed in the protection region.

15. The measuring system of claim 1 , wherein the protective cover includes a screw thread configured for screwed connection of a conduit surrounding the cable.

16. The measuring system of claim 1 , wherein the protective cover is structured to increase the impact resistance of the measuring system in the protection region such that the measuring system fulfills industry requirements of a protection class, which the measuring system could not fulfill without the protective cover.
