Measuring Principle


By using wear-resistant diamond needle parts and precise motor drive structure, the sensor walks at the absolute linear movement specified by the standard, and walks at the correct horizontal distance.When the low test force tentacles across the wave peak and wave valley, the high precision inductive bridge circuits will detect their vertical displacement through modulation, amplification and phase sensitive detection wave. The sensitivity can up to nanoscale level.The voltage signal corresponding to the roughness is transmitted to a high computing power ARM + DSP processor, using a standardized algorithm to calculate the surface roughness parameters instantly.
