Introduction

Portable roughness Tester is a portable stylus surface roughness shape measuring instrument, which is suitable for the detection of workshop verification stations, laboratories, measurement rooms and other environments. The measurement parameters are in line with international standards and compatible with the standards of some industrially developed 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.

Principle

When measuring the surface roughness of the workpiece, the instrument first puts the sensor on the surface to be measured on the workpiece, and then starts the instrument to measure, and the precision driving mechanism inside the instrument drives the sensor to slide along the measured surface at a constant velocity, and the sensor feels the roughness of the measured surface through the built-in sharp stylus, and the roughness of the measured surface of the workpiece will cause the displacement of the stylus, and the displacement changes the inductance of the sensor inductance coil. Thus an analog signal proportional to the measured surface roughness is generated at the output end of the phase-sensitive Detector, and the signal enters the data acquisition system after amplification and level conversion, and the DSP chip performs digital filtering and parameter calculation on the collected data, and the measurement results are given on the display, can also be output on the printer, and can also communicate with the PC.
