Diameter, Eccentricity, concentricity
The diameter of an object can be established in different ways. If the center of the object is known, a single sensor is sufficient for the measurement whose result is evaluated with the position of the center point or the axis. If the position of the center point is not known, the diameter is measured directly using two sensors. The distance information here is also evaluated together. In particular cases, if the opaqueness of the object allows this, the determination of the diameter can also be made directly using a confocal sensor.
Acquisition of the internal diameter of tubes

Show detailsCoil diameter
The optical optoNCDT ILR length sensor continuously measures the surface of the coil and detects the diameter. By unwinding, the diameter of the coil is reduced, which is detected based on the increasing distance between the coil surface and the sensor.
Show detailsCoil unwinding
In the metal industry, rolled strips are reeled for transportation on coils. In the further processing when coils are unreeled, it is important to know how much material has already been unwound. This task can be easily solved by using an optical optoNCDT ILR length sensor.
