RUNJIE RJ941 Surface Roughness Tester

RJ941

Surface roughness meter

product description

The portable roughness meter is a portable stylus surface roughness and 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 industrially developed countries such as the United States, Germany, Japan, and the United Kingdom. Measurement results can be displayed numerically and graphically on the LCD display or output to a printer.

Applicable materials

It is suitable for processing industry, manufacturing, testing, commodity inspection and other departments. It is mainly suitable for on-site inspection of large workpieces and production lines, as well as outbound verification of testing, measurement, commodity inspection and other departments.

Fundamental

When this instrument measures the surface roughness of a workpiece, it 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 a straight line at a constant speed along the measured surface. The sensor passes through the built-in The sharp stylus feels the roughness of the measured surface. At this time, the roughness of the measured surface of the workpiece will cause the stylus to shift. This displacement will change the inductance of the sensor inductance coil, thus generating a signal at the output end of the phase-sensitive Detector. The analog signal is proportional to the roughness of the measured surface. After amplification and level conversion, the signal enters the data acquisition system. The DSP chip performs digital filtering and parameter calculation on the collected data. The measurement results are given on the display or can be displayed on the display. output on the printer and can also communicate with the PC.
