Tablet surface flatness measurement
Glass substrate positioning
pic03
The judgment level adjustment function ensures stable detection and measurement of even transparent workpieces.
Detection of clearance between rollers
Detection of clearance between rollers
The clearance between rollers can be measured for stabilizing the workpiece quality. The compact head is easy to install.
Shaft diameter measurement
Shaft diameter measurement
Shaft diameters can be measured. The original head structure and proprietary algorithm achieve stable detection without being affected by secondary reflections by metal surfaces.
Measurement of motor shaft eccentricity
Measurement of motor shaft eccentricity
Shaft eccentricity can be measured by using the central position detection mode and measuring the distance to the shaft center.
