Abstract

The present disclosure relates to an apparatus for determining and/or monitoring a temperature of a medium in a containment, including a temperature sensor for registering temperature, and a flexible, heat-conductive support element, which is arrangeable on an outer surface of a wall of the containment, wherein the temperature sensor is secured to the support element.

First claim

The invention claimed is:

1. An apparatus for determining and/or monitoring a temperature or flow of a medium in a containment, the apparatus comprising:
a temperature sensor configured to detect a temperature;
a flexible, heat-conducting support element including a support element inner side which is disposable on an outer surface of a wall of the containment, and a support element outer side, and wherein the temperature sensor is secured upon the support element outer side; and
a thermal insulation unit, which at least partially surrounds the support element, wherein the temperature sensor is disposed between the support element and the thermal insulation unit in a layered arrangement including as an innermost layer the support element and as an outermost layer the thermal insulation unit.

2. The apparatus of claim 1 , wherein the temperature sensor is a resistance element or a thermocouple.

3. The apparatus of claim 1 , further comprising at least one reference element configured for in situ calibrating and/or validation of at least the temperature sensor, wherein the at least one reference element is secured to the support element and is comprised of at least one material, which at least one material has at least one phase change at at least one predetermined phase change temperature in a temperature range suitable for calibrating the temperature sensor, wherein the at least one material remains in a solid state in the at least one phase change.

4. The apparatus of claim 1 , further comprising a heating element, which is secured to the support element.

5. The apparatus of claim 1 , wherein the support element is comprised of a metal woven or felt fabric.

6. The apparatus of claim 5 , wherein the metal includes copper.

7. The apparatus of claim 1 , wherein the thermal insulation unit is comprised of a silicone or silicone foam.

8. The apparatus of claim 1 , further comprising at least one guide configured as to lead at least one connection line of at least the temperature sensor, and the at least one guide extends in an outward direction through the thermal insulation unit.

9. The apparatus of claim 1 , wherein at least the temperature sensor is secured to the support element by a flexible adhesive.

10. The apparatus of claim 1 , wherein the support element is comprised of at least two flexible layers arranged one atop the other.

11. The apparatus of claim 1 , further comprising a securement means configured to releasably secure the apparatus to the containment.

12. The apparatus of claim 11 , wherein the securement means is further configured to ensure a predeterminable compressive pressure of the support element on the containment.

13. The apparatus of claim 11 , wherein the securement means includes at least one elastic element.

14. The apparatus of claim 1 , wherein the containment is a pipeline, and wherein the support element is configured as to be disposed around the pipeline perpendicular to longitudinal axis of the pipeline.

15. The apparatus of claim 1 , wherein:
the support element extends in a circumferential direction at least partially around an axis, and the thermal insulation unit extends in the circumferential direction at least partially around the axis; and
the thermal insulation unit includes a first end located axially outward, in a first axial direction, of the support element, and a second end located axially outward, in an opposite axial direction, of the support element.

16. The apparatus of claim 15 wherein the support element extends fully circumferentially around the axis, and the thermal insulation unit extends fully circumferentially around the axis.
