Intelligent digital portable surface roughness tester

Product Description

Product Overviews
It applies to production site and can be used to measure surface roughness of various machinery-processed parts, especially for roughness measurement of complex parts,
such as:Flat, Curved surface, Grooves and Holes.
Capable of evaluating surface textures with a variety of parameters according to various national standards and international standard.
The measurement results are displayed digital/graphically on the LCD, and output to the printer.
 
Work 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.
