Description
Overview
Be compatible with the four standards of ISO, DIN, ANSI, and JIS. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe which results in a change of the inductive amount of induction coils to generate an analog signal, which is in proportion to the surface roughness at the output end of the phase-sensitive rectifier. The exclusive DSP process calculates and then outputs the measurement results on LCD.
