Title: Apparatus for measuring displacement of pipe
Inventor: INAO TAKESHI
IPC: G01D5/26
Filed: 1985-07-05
Abstract: PURPOSE:To certainly enable measurement even with respect to high frequency such as vibration, by detecting the displacement quantity of a pipe on the basis of the change in the quantity of light due to the shift of the optical axis of an optical fiber. CONSTITUTION:A pipe 25 is inserted through the holes of the light emitting part mount jig 1 and light receiving part mount jig 2 of an optical fiber to be grasped so as to be held between both jigs 1,2. The optical axes of a light emitting side optical fiber 8 and a light receiving side optical fiber 12 are matched on the same axis and set in opposed relationship so as to adjust the gap between both leading ends thereof to 1mm or less. Next, when load such as vibration is applied to the pipe 25, said pipe 25 is displaced by fatigue and, therefore, the optical axes between both fibers 8, 12 are shifted and the light receiving quantity of the fiber 12 changes. This change is converted to an electrical output signal by a photoelectric converter circuit 19 while said output signal is compare with the output signal from a sine wave transmission circuit 17 by a detection circuit part 20 and judged. By this method, the displacement quantity of the pipe can be read as the electrical output signal by a reading circuit 24. Because this system is a non-contact one, the measurement of displacement with high frequency is enabled and frequency characteristics are excellent and displacement quantity can be continuously measured with good accuracy.
