Large diameter laser outside diameter measuring instrument LDM-150 LDM-210 LDM-380. Laser diameter measuring instrument is the high-accuracy installment that uses the laser scan to carry on the no-contacts on-line measurement. It is mainly used in measuring of outer diameter and adjusting the extruder screw or traction speed, to control the outside diameter. It is applicable to measure and control the diameter of metal wires, glass, pipes, wire and cable, etc.
It can also be applied to the outer diameter of workpiece and size measurements.
