Foil-thickness measuring device |
摘要 |
A device for continuously measuring the thickness of a foil includes a radiation source opposite a radiation detector, and a movement member which moves the radiation source and detector synchronously in a width-direction of the foil. A signal generator generates a signal indicating a position of a portion of the foil whose thickness is being measured, and a counter having a plurality of integrating channels integrates detection signals output from the detector to generate an integrated count number for each channel. A signal switching member switches each of the plurality of integrating channels of the counter according to signals generated by the signal generator, and a calculator calculates a foil thickness from the integrated counted number for each channel of the counter. This structure allows continuous and precise measurement of the foil's thickness.
