What is the thickness gauge
- Apr 17, 2017 -

Radiation thickness gauge is divided into two categories. A class is to measure the thickness of the material which is absorbed and the intensity varies by using the radiation wires of β and γ to penetrate the measured materials. The other is the use of radiation-ray backscatter principle, radiation through the material when the scattering phenomenon, when the scattering angle exceeds 90 °, and the inverse scattering intensity is related to the material thickness, measured from the material back-scattering ray intensity can be measured thickness.

The common thickness gauge has the radiation thickness gauge, the X-ray thickness gauge, the high frequency eddy current type thickness gauge, the microwave type thickness gauge and the roller contact inductance thickness gauge.
