Types and working principles of roughness meters
The needle tracing method is also called the stylus method. When the stylus is directly across the surface of the workpiece to be measured, due to the peak and valley of the measured surface contour, the stylus will move up and down in the direction perpendicular to the surface of the measured contour, and this movement is sent to the signal through the electronic device. Zoom in, and then output data or graphics related to roughness through a zero meter or other output devices.
