Device and method for detecting deposits

摘要

A device and a method for detecting deposits (9) on walls (2) that are covered by a medium, in which as sensor (1) is integrated in the wall (2). A component (3) of the sensor (1) locally heats the medium in a region (4), and the temperature of the medium around the component (3) is detected. The sensor (1) relays temperature measurement signals to an analysis unit (8), where the degree of deposit formation is determined, e.g., by comparison with stored reference data.

1. A device for detecting the presence of deposits on a wall which is covered by a medium, said device comprising:
a sensor integrated in or placed on the wall, said sensor including a heating element for heating the medium in an area surrounding the heating element, and said sensor detecting a temperature of said medium in the heated area or a temperature of the heating element; and an evaluation unit operatively connected to said sensor for receiving detected temperature signals from said sensor; said evaluation unit determining a degree of deposit formation on the wall by comparing received temperature signals with predetermined reference temperature data, wherein
the heating element of the sensor locally heats the medium during a test measurement in which the detected temperature signals are generated to a temperature corresponding to a temperature generated in a reference measurement in which the predetermined reference temperature data is generated, andthe evaluation unit determines the degree of deposit formation based on a difference in heating intensity required to attain the temperature in the test measurement and the temperature generated in the reference measurement.
