Abstract

A measuring device for detecting the amount of moisture in and the temperature of a flowing medium is disclosed. Flow-directing elements which mix the flowing medium and direct it in a desired direction are arranged in the measuring device. The average temperature of the medium can thus be detected using a suitably arranged temperature sensor. In addition, the moisture sensor may be arranged in such a manner that a selective amount of moisture in the medium is detected.

Claims (38)

1. A measuring device comprising:

a moisture sensor for detecting an amount of moisture in a flowing medium;

a temperature sensor for detecting a temperature of the flowing medium; and

a carrier, the moisture sensor and the temperature sensor arranged on the carrier, the carrier having flow-directing elements, wherein the carrier has a channel having an inlet opening configured to receive the flowing medium flowing into the channel, wherein the channel has a constricted region with a cross section that is smaller than a cross section of the inlet opening, wherein the channel is in the form of a funnel and has a funnel neck, and wherein the moisture sensor is arranged in a region of the inlet opening and the temperature sensor is arranged in a region of the funnel neck or wherein the temperature sensor is arranged in a region of the inlet opening and the moisture sensor is arranged in a region of the funnel neck.

2. The measuring device as claimed in claim 1 , wherein the flow-directing elements are suitable for directing the flowing medium in a direction of the moisture sensor and/or the temperature sensor.

3. The measuring device as claimed in claim 2 , wherein the flow-directing elements are suitable for concentrating the flowing medium.

4. The measuring device as claimed in claim 1 , wherein the flow-directing elements are suitable for mixing the flowing medium.

5. The measuring device as claimed in claim 1 , wherein the moisture sensor is arranged in a region of the inlet opening and the temperature sensor is arranged in a region of the funnel neck.

6. The measuring device as claimed in claim 1 , wherein the temperature sensor is arranged in a region of the inlet opening and the moisture sensor is arranged in a region of the funnel neck.

7. The measuring device as claimed in claim 1 , further comprising an element that comprises a thermally conductive material and is thermally connected to the temperature sensor.

8. The measuring device as claimed in claim 7 , wherein the element comprises a grating through which the flowing medium flows.

9. The measuring device as claimed in claim 1 , further comprising a shielding element that prevents the flowing medium from flowing directly onto the moisture sensor and/or the temperature sensor.

10. The measuring device as claimed in claim 1 , wherein the flowing medium comprises air.

11. A method comprising:

locating a measuring device in a flowing medium;

directing the flowing medium toward a temperature sensor and a moisture sensor using flow-directing elements within the measuring device, the temperature sensor and moisture sensor arranged on a common carrier of the measuring device;

detecting an amount of moisture in the flowing medium using the moisture sensor; and

detecting a temperature of the flowing medium using the temperature sensor,

wherein the carrier has a channel having an inlet opening through which the flowing medium flows into the channel, wherein the channel is in the form of a funnel and has a funnel neck, and wherein the moisture sensor is arranged in a region of the inlet opening and the temperature sensor is arranged in a region of the funnel neck or wherein the temperature sensor is arranged in a region of the inlet opening and the moisture sensor is arranged in a region of the funnel neck.

12. The method of claim 11 , wherein directing the flowing medium comprises concentrating the flowing medium.

13. The method of claim 11 , wherein directing the flowing medium comprises mixing the flowing medium.

14. The method of claim 11 , wherein directing the flowing medium comprises preventing the flowing medium from flowing directly onto the moisture sensor and/or the temperature sensor.

15. A measuring device comprising:

a moisture sensor for detecting an amount of moisture in a flowing medium;

a temperature sensor for detecting a temperature of the flowing medium; and

a carrier, the moisture sensor and the temperature sensor arranged on the carrier, the carrier having flow-directing elements, wherein the carrier has a channel having an inlet opening through which the flowing medium flows into the channel, wherein the channel has a non-constricted region whose cross section is equal to a cross section of the inlet opening, the moisture sensor and/or the temperature sensor being arranged in the non-constricted region; and

an element comprising a thermally conductive material and thermally connected to the temperature sensor.

16. A measuring device comprising:

a moisture sensor for detecting an amount of moisture in a flowing medium;

a temperature sensor for detecting a temperature of the flowing medium;

a carrier, the moisture sensor and the temperature sensor arranged on the carrier, the carrier having flow-directing elements; and

an element that comprises a thermally conductive material and is thermally connected to the temperature sensor.

17. The measuring device as claimed in claim 16 , wherein the element comprises a grating through which the flowing medium flows.

18. A measuring device comprising:

a moisture sensor for detecting an amount of moisture in a flowing medium;

a temperature sensor for detecting a temperature of the flowing medium; and

a carrier, the moisture sensor and the temperature sensor arranged on the carrier, the carrier comprising flow-directing elements, wherein the flow-directing elements are suitable for concentrating the flowing medium, and wherein the flow-directing elements concentrate the flowing medium in the direction of the moisture sensor and/or the temperature sensor; and

an element that comprises a thermally conductive material and is thermally connected to the temperature sensor.
