summary
The portable roughness meter is a portable stylus surface roughness shape measuring instrument, suitable for testing in workshop calibration stations, laboratories, measurement rooms, and other environments. The measurement parameters comply with international standards and are compatible with the standards of some industrialized countries such as the United States, Germany, Japan, and the United Kingdom. The measurement results can be displayed digitally and graphically on the LCD display, or output to a printer.

Basic Principles
When measuring the surface roughness of a workpiece, this instrument first places the sensor on the measured surface of the workpiece, and then starts the instrument for measurement. The precision driving mechanism inside the instrument drives the sensor to slide along the measured surface at a constant speed in a straight line. The sensor senses the roughness of the measured surface through the built-in sharp stylus. At this time, the roughness of the measured surface of the workpiece will cause displacement of the stylus, This displacement causes a change in the inductance of the sensor coil, resulting in an analog signal proportional to the measured surface roughness at the output end of the phase sensitive detector. After amplification and level conversion, the signal enters the data acquisition system, and the DSP chip performs digital filtering and parameter calculation on the collected data. The measurement results are displayed on the display, can also be output on a printer, and can also communicate with a PC.
