Abstract
PURPOSE: To ensure an accurate measurement for the freezing thickness by securing such electrode structure that the temperature of the freezing detection electrode may follow the temperature of cooled water flowing in touch with the freezing surface of the cooling tube.
CONSTITUTION: Freezing detection electrode 5 of the electrod bar is made to oppose to cooling tube 1 and located along the radius direction of the tube. When cooled water 3 flows in touch with the surface of tube, freezing layer 2 grows gradually to reach electrode 5. In this case, the shift of the heat is cut off for electrode 5 from the supporter or the like owing to existence of heat cut-off electric conduction part 8, and thus the temperature of the electrode follows the temperature of the cooled water flowing in touch with the freezing surface of tube 1. However, the electrode is buried into the freezing surface as the surface grows, and as a result the electrode surface is covered by the ice layer. Accordingly, the current flowing through water 3 is cut off by layer 2, thus ensuring the correct detection for the set position of electrode 5. In this way, the freezing thickness can be measured accurately, at the same time securing the optimum state for the freezing thickness.
