Laser Diameter Measuring Gauge Model LDM-100

Model LDM-100 outside diameter measuring range 0.2 to 95mm, Large diameter laser outside diameter measuring instrument

Model LDM-100 Laser diameter measuring gauge 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.

Laser Gauge Features
1.non-contact laser diameter measurement, high speed, high accuracy and good repeatability.
2. Real time outside diameter and roundness display, improve quality control and production efficiency, reduce the waste of materials.
3. Various digital and analog control signal functions, to achieve fully automated production.
4. Various preset functions,nominal value, the upper and lower tolerance, alarm control presets, easy to operate.
5. Standard data port connection ready,compatible software for data analysis development convenience.
