Abstract

A sealing system comprising a seal with a sealing lip and a sensor device provided with a measuring probe that extends into a space to be sealed off. The measuring probe during the intended use is exposed to the medium to be sealed.

Claims

1. A sealing system comprising:

a seal with a sealing lip; and

a sensor device with a measuring probe, the measuring probe extending into a space to be sealed off

wherein the measuring probe is exposed to the medium to be sealed off in the space in which it extends.

2. The sealing system as defined in claim 1, wherein in the space to be sealed off there is disposed a retaining device that retains the medium to be sealed off, the measuring probe extending into the retaining device.

3. The sealing system as defined in claim 2, wherein the retaining device is fastened to the seal.

4. The sealing system as defined in claim 2, wherein the retaining device is provided with a retaining lip which at least partly surrounds a shaft

5. The sealing system as defined in claim 4, wherein the retaining lip surrounds the shaft by at least partly touching it.

6. The sealing system as defined in claim 2, wherein the retaining device is fastened to the sensor device.

7. The sealing system as defined in claim 2, wherein the retaining device is provided with a draining hole.

8. The sealing system as defined in claim 1, wherein the measuring probe is a transmitter for measuring the age of the medium to be sealed off.

9. The sealing system as defined in claim 1, wherein the measuring probe is a transmitter for measuring at least one of temperature, pressure, and filling quantity of the medium to be sealed off.

10. The sealing system as defined in claim 1, wherein the seal is provided with a support element, the support element having a recess in which the sensor device is disposed.

11. The sealing system as defined in claim 1, further comprising a cleaning arrangement including a cleaning line and a cleaning nozzle, the cleaning nozzle directed toward the measuring probe.

12. A housing cover comprising the sealing system as defined in claim 10, wherein the support element is designed as a sealing flange with a recess, the sensor device being disposed in the recess.

13. The housing cover as defined in claim 12, wherein the sealing flange is made of an injection-molded plastic material.

14. The housing cover as defined in claim 12, wherein the sealing flange is made of a metallic material.
