Description
- The Surface Roughness Tester is suitable for use in production and for mobile measurements when you need a small, portable device.
- It is easy to operate, self-contained, performs fast measurements, and has stable accuracy and convenience.
- This tester is applied on the production site and can be used to measure the surface roughness of various parts processed by machine tools, and is also capable of evaluating surface texture through a variety of parameters in accordance with various national standards and international standards such as ANSI, DIN, JIS, ISO.
- The measurement results are displayed digitally and graphically on the LED display and output to the printer.
- When measuring the surface roughness of a part, the probe is placed on the surface of the part and then traversed at a constant speed.
- The pickup acquires the surface roughness through a sharp stylus in the pickup.
- The roughness causes a displacement of the probe, which leads to a change in the inductance value of the induction coils, thus generating an analog signal that is proportional to the surface roughness at the output end of the phase-sensitive rectifier.
- This signal is fed into the data acquisition system after amplification and level conversion.
- This collected data is then processed through digital filtering and parameter calculation by the DSP chip, and the measurement result can be read on the display, printed on the printer, and transferred to a PC.
