Working Principle

When measuring the surface roughness of the workpiece, the instrument first puts the sensor on the workpiece to be measured.On the surface, then the starting instrument is measured, and the sensor is driven by the precision driving mechanism inside the instrument.The device glides along the measured surface for a straight line, and the sensor is measured by a built-in sharp touch needle.The roughness of the surface, when the roughness of the surface of the workpiece is measured, causes the needle to produce the displacement.The displacement changes the inductance of the inductance coil of the sensor, thus the output of the phase sensitive detector.The end produces an analog signal proportional to the measured surface roughness, which is amplified and level.After the conversion, the data acquisition system is entered, and the DSP chip is digital filtering for the collected data.The parameters are calculated, the results are given on the display.
