The X-ray thickness gage is used to measure the thickness of a strip continuously without contacting that strip. This gage uses the fact that the amount of radiation that passes through the strip varies with the thickness of that strip. The is a high quality thickness gage for cold rolling achieving outstanding safety, operability, accuracy and cost-performance developed over many years. It has the following features.· Noise immunity is improved by digitizing the signals between the measuring head and the equipment cabinet.
· The operation-PC uses Windows® NT, and is a user-friendly PC.· A newly-developed X-ray generator is used, providing extremely accurate measurement results with a quick response time. The TOSGAGE-7525 focuses X-ray beams finely in the strip width direction to improve thickness resolution in the strip width direction, and making it suited to measuring the shape of the section of measured materials. The TOSGAGE-7525 can also be used as a AGC backup for when the fixed thickness gage (TOSGAGE-7521/7522) has failed.

When the X-rays emitted from the X-ray generator pass through the material being measured, they are scattered and absorbed by that material. The X-rays that pass through the material are received by the detector (ionization chamber) and are converted into electrical signals (ionization current) proportional to the quantity of X-rays. These signals are subjected to A/D conversion at the integrated A/D converter before being sent to the microcomputer by the highspeed serial interface. At the equipment cabinet, these signals are calculated by the microcomputer and then output as thickness signals.
Integrated A/D converter Thickness gage Deviation output Detector Calibration curve
Measured material Standard changer Calibration information
Measurement Method The is a single-beam thickness gage that uses previously calibrated standard plates to create and store a calibration curve throughout the entire measurement range. The signals detected for the X-rays that have passed through the measuring material during measurements are applied to the calibration curve to derive the thickness.
