Abstract
PURPOSE: To ensure a simultaneous and contactless measurement for thickness of a tubular material, by shifting the tubular material toward its axis, decentralizing the measuring systems along the shift direction of the tubular material and then supplying the measurement value signal into an arithmetic device with a time delay and in accordance with the shift of the tubular material.
CONSTITUTION: Three sets of measuring systems 1, 2 and 3 in which the ratiation beam sources and the detectors are combined are used, and 1-1, 1-2, 1-3 and 1-4 are used for the radiation beam sources of the 1st measuring system 1. In the same way, 2-1W2-4 and 3-1W3-4 are used for the radiation beam sources of the 2nd and 3rd measuring systems respectively. A pipe 5 to be measured is shifted toward an arrow mark in a speed v and without turning round the axis of the pipe. The systems 1W3 are installed with spaces l1 and l2, and the output signals I1', I2' and I3' obtained from these systems are used to obtain the three points on the tube circumference of the pipe 5. Then the value of lateral section at the same part of the pipe 5 is supplied to a signal processor 10 according to the rotational frequency of a roll 6. Thus the thickness of the pipe 5 is measured.
