How to use the Surface Roughness Tester correctly


The Surface Roughness Tester is a hand-held instrument suitable for the production environment and mobile measurement. It can measure the surface roughness of a variety of machined parts. The corresponding parameters can be calculated according to the selected measurement conditions and displayed on the display. All measurement parameters and contour graphics. The instrument is easy to operate, fast in measurement, stable in accuracy, easy to carry, and can measure the main parameters of international standards. The instrument strictly implements international standards.


Let's talk about the following small series, how to use the Surface Roughness Tester correctly


Surface Roughness Tester is also called roughness meter, surface finish meter, surface roughness tester, roughness measuring instrument, roughness meter, roughness tester and other names. When measuring the surface roughness of the workpiece, the sensor is placed on the surface to be tested, and the driving mechanism inside the instrument drives the sensor to slide at a constant speed along the surface to be tested. The sensor senses the roughness of the surface to be tested through the built-in sharp stylus. When the roughness of the surface to be measured of the workpiece causes displacement of the stylus, the displacement changes the inductance of the inductor of the sensor, thereby generating an analog signal proportional to the roughness of the surface to be measured at the output of the phase sensitive rectifier, and the signal passes through After amplification and level conversion, the data acquisition system is entered. The DSP chip performs digital filtering and parameter calculation on the collected data. The measurement result is read on the liquid crystal display, and can also be output on the printer, and can also communicate with the PC.
