Roughness Tester Measurement Principle

When measuring the surface roughness of a workpiece, place the sensor on the surface to be measured. The driving mechanism inside the instrument drives the sensor to slide along the surface to be measured at a constant speed. The sensor senses the roughness of the surface to be measured through the built-in sharp stylus. At this time, the roughness of the surface to be measured causes the stylus to move. This displacement changes the inductance of the sensor's inductor coil, thereby generating an analog signal proportional to the roughness of the surface to be measured at the output end of the phase-sensitive rectifier. After amplification and level conversion, the signal enters the data acquisition system. The DSP chip performs digital filtering and parameter calculation on the collected data. The measurement results are read out on the LCD display, output on a printer, and can also communicate with a PC.
