Abstract
PURPOSE: To eliminate the error due to mutual interferences by generating the positional signals of the respective detecting portions of thickness meters at position detecting portions, by calculating the spacing between the detectors with the use of a distance meter and by compensating the metered signals with the use of the output as well as the preset compensation value of the mutual interference.
CONSTITUTION: The center thickness of a test piece 1 and the thickness of a plate end are metered and generated as metering signals by means of a first thickness meter 2a, a detector 4a, a beam souce container 5a, and a second thickness meter 2b, a detector 4b, and a beam souce container 5b. There are provided position detectors 7a and 7b, which are operative to detect the respective positions of the detecting portions of the first and second thickness meters 2a and 2b, and the positional signals therefrom are fed to a distance meter 8 so that the spacing inbetween is metered. The output of this meter 8 is fed to a compensation calculating device 10, which is supplied with the metered signals from the detectors through data taking devices 9a and 9b. The device 10 is stored with the preset compensated value of the mutual interference, and the metered signals from the detecting portions are compensated in accordance with the output from the meter 8 so that the error in the mutual interference may be compensated.
