An amorphous strip thickness gauge

Abstract

This utility model discloses an amorphous strip thickness gauge, including a detection frame with a detection cavity inside. Two sets of lead screws are symmetrically installed vertically within the detection cavity. A guide rod is provided on one side of each lead screw, and a support plate is fitted onto both the guide rod and the lead screw. An upper X-ray emission tube and an upper detector are mounted on the upper support plate. The advantages are: by setting up a dual-station, upper and lower coaxial measurement structure consisting of an upper X-ray emission tube, a lower detector, a lower X-ray emission tube, and an upper detector, this utility model can simultaneously convert the vertical movement of the strip into changes in the measured values ​​of the upper and lower measurement modules. Through data fusion processing, the influence of the vertical movement can be directly offset, eliminating the maximum error source of online measurement in principle. The measurement accuracy is extremely high, effectively improving the measurement effect and performance of the device.
