Description
The MR200 surface roughness tester is a new upgrade instrument which adopts the newest processor. This instrument adopts needle scanning method to test the surface roughness of the work piece. When measuring roughness of part surface, the probe is placed on the surface of the part and then tracing the surface at constant rate. The probe acquires the surface roughness by the sharp stylus in probe. The roughness causes displacement of probe which results in change of inductive value of induction coils thus generate analogue signal which is proportional to surface roughness at output end of phase-sensitive rectifier. This signal enters data collection system after amplification and level conversion. After that, those collected data are processed with digital filtering and parameter calculation by ARM chip and the measuring result can be read on OLED display. The results can be printed by Bluetooth printer.
