Roughness tester overview
The surfaces roughness tester 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. This tester applies to production site and can be used to measure surface
roughness of various machinery-processed parts. This tester is 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 OLED and can be
outputed to the printer.

1.2 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 OLED, printed through
printer and communicated with PC.
