FIELD: measurement equipment.
SUBSTANCE: device and method for determining the temperature of a pipe shaft. The device is provided with the first temperature sensor for measuring the first temperature of the outer side of the pipe shaft in the first position of the pipe shaft, and a data processing device configured to compare the first temperature with the second temperature of the outer side of the pipe shaft in the second position of the pipe shaft located at a distance from the first position in the feed direction of the pipe shaft, and determining the temperature inside the pipe shaft and/or on the inside of the pipe shaft at a certain position of the pipe shaft based on the comparison of the first and the second temperatures.
EFFECT: higher accuracy of information on the temperature of the pipe shaft enabling optimization of the production process; improved accuracy of measurements when calculating the diameter and/or wall thickness of the pipe shaft at the measurement site, as well as the length, wall thickness and diameter of the pipe shaft after cooling.
