SRT-6200 handheld roughness measuring instrument Introduction
The SRT-6200 handheld roughness measuring instrument uses computer technology and meets the national standard GB / T 6062 and ISO, DIN, ANSI and JIS four standards. It can be widely used in production sites and can measure the surface roughness of various machined parts. The corresponding parameters are calculated according to the selected measurement conditions, and all measurement parameters are clearly displayed on the LCD. When measuring the surface roughness of the workpiece, the sensor is placed on the measured surface of the workpiece, and the internal driving mechanism of the instrument drives the sensor to slide along the measured surface at a constant speed. The sensor senses the measured surface roughness through the built-in sharp stylus. The roughness of the measured surface of the workpiece causes a displacement of the stylus, which changes the inductance of the inductor coil of the sensor, so that an analog signal proportional to the roughness of the measured surface is generated at the output of the phase-sensitive rectifier. The signal passes through After amplification and level conversion, it enters the data acquisition system. The DSP chip performs digital filtering and parameter calculation on the collected data. The measurement results are displayed on the liquid crystal display. At the same time, it can communicate with the PC for data analysis and printing. Features
