Surface roughness meter
It is used for measuring the surface roughness of products. When measuring the surface roughness of the workpiece, the sensor is placed on the measured surface of the workpiece, and the driving mechanism inside the instrument drives the sensor to slide along the measured surface at a constant speed. The sensor senses the roughness of the measured surface through the built-in stylus. At this time, the roughness of the measured surface of the workpiece causes the stylus to produce longitudinal displacement, which changes the inductance of the sensor inductance coil, thus, an analog signal proportional to the measured surface roughness is generated at the output of the phase-sensitive rectifier, and the signal enters the data acquisition system after amplification and level conversion. The ARM chip performs digital filtering and parameter calculation on the collected data, and the measurement results are read out on the liquid crystal display.
