Wire, cable, pipe, Laser diameter gauge is the high-accuracy survey installment that uses the laser scan to carry on Non-contact the on-line
measure.
Mainly used in a variety of wires, cables, pipe production line,
the measurement of outer diameter and adjust the extruder screw speed or traction
speed, to control the purpose of OD. Can also be applied to the outer diameter of
workpiece and size measurements.
