Surface Roughness Tester ART200 model
Introduction
ART200 surfaces roughness measure instrument is suitable for shop floor use and mobile measure to need of a small handheld instrument, it operation simple, function overall, measure fast, accuracy stability, take convenience. The AR200 is capable of evaluating sueface textures with a variety of parameters according to various national standards and international standard.The measurement results are displayed digitall/graphically on the LCD,and output to the printer.
Measurement principle
When measuring roughness of part surface, the pickup is placed on the surface of the part and then tracing the surface at constant rate. The pickup acquires the surface roughness by the sharp stylus in pickup. The roughness causes displacement of pickup which results in change of inductive value of induction coils thus generate analogue signal which is in proportion 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 DSP chip and the measuring result can be read on LCD, printed through printer and communicated with PC.
