Method and device for the detection of infiltrations in liquid-filled channels

摘要

The method of detecting infiltrations in liquid-filled channels, wherein the temperature of the liquid with a temperature sensor arrangement is detected and the sensor arrangement is moved along the channel and by means of at least two temperature sensors arranged at a fixed distance from each other, which are immersed in the liquid, a temperature difference between the temperature sensors is determined, characterized in that the rod-shaped temperature sensors by means of a kinematic in a predetermined distance from the channel wall to be moved, that the temperature difference is compared to a predefined threshold value and in that in the case of exceeding the predetermined threshold value is closed to an infiltration.
