Roller Skating Contact Inductance Thickness Gauge

Used to measure the thickness of strips or plates. When the tested material passes between the roller set consisting of a movable and a fixed roller, the change in the thickness of the workpiece causes the radial displacement of the movable roller. This displacement pushes the iron core of the inductive sensor, so that the inductive coil produces an output signal proportional to the thickness and displays it. This measurement method has high accuracy and has nothing to do with the physical and chemical properties of the tested material, but the roller is easy to damage the measured surface.
