Ink wet film wheel

The wet film thickness gauge consists of two concentric wheels, with the outer wheel slightly larger in diameter than the inner wheel. During measurement, it rolls over the wet ink surface, causing the outer wheel to pick up ink while the inner wheel remains clean. The height difference between the two wheels provides a reading of the wet film thickness. It is used for on-site rapid control of coating application thickness.
Selection
Select the measurement range according to the thickness range of the film to be measured, with 0-150μm being the conventional choice. Choose the wheel width based on the substrate flatness; narrow wheels are used for curved substrates. Stainless steel is suitable for solvent-based inks, while carbon steel is used for water-based systems. The clearance of the wheel axle affects accuracy and should be regularly calibrated using a standard gauge block.
