1. Features

The instrument uses computer technology, in line with GB GB / T 6062 and ISO, DIN, ANSI and JIS four standards, can be widely applied to the production site, can measure a variety of machined parts of the surface roughness, according to the selected measurement conditions The corresponding parameters in the liquid crystal display clearly shows all the measurement parameters.When measuring the surface roughness of the workpiece, the sensor on the workpiece surface, the drive mechanism within the instrument drive the sensor along the measured surface to do the same speed taxi , The sensor through the built-in sharp stylus feel the measured surface roughness, then the workpiece surface roughness caused by the displacement of the stylus, the displacement of the sensor inductance coil inductance changes, so the phase sensitive rectifier output Generating the analog signal which is proportional to the measured surface roughness. After the signal is amplified and leveled, it enters the data acquisition system. The DSP chip digitizes the collected data and calculates the parameters. The measurement result is displayed on the liquid crystal display. Can communicate with PC, to achieve data analysis and printing.
