Measurement principle
When measuring the surface roughness of the workpiece, the instrument first puts the sensor on the surface of the workpiece to be measured, and then starts the instrument for measurement. The precision driving mechanism inside the instrument drives the sensor along the measured surface to do constant speed straight slide, and the sensor feels the roughness of the measured surface through the built-in sharp stylus. At this time, the roughness of the workpiece's measured surface will cause the stylus to produce displacement. The displacement causes the inductance of the sensor inductor to change, thus generating an analog signal proportional to the measured surface roughness in the output end of the phase-sensitive detector. The signal enters the data acquisition system after amplification and level conversion. The DSP chip performs digital filtering and parameter calculation on the collected data, and the measurement results are given on the display or output on the printer. It can also communicate with a PC.
