In order to measure the coating thickness of the cable that is continuously extruded from several times by placing an M1 convex wave sensor in the water of the water-cooled I-rough placed in the Kusol passage, we used the same material as the 9-pull coating. When a reference sample with a known thickness is oriented in water near the coating J9 measurement position of the water cooling trough,
The thickness of this base 11ξ sample and the thickness of the cable coating are measured with an ultrasonic sensor, and the coating thickness of the couple is calculated from the measured values of both measurements as 1) i.
