ABSTRACT:
A surface roughness analyzer uses a varying electrical output of a transducer attached to a stylus scanning a surface to provide a pulse train having a pulse duration representative of the peak support width established when the output crosses a reference level. During a scan an average arithmetic average roughness is indicated and the pulses are counted which occur within selected ranges of peak support width. Readouts at the end of the scan include average arithmetic average surface roughness, bearing area and peak count with reference levels based on roughness range or bearing area.
