Product Name: Laser Diameter Gauge

Product Model: LGD-02


1, Outline of LGD-02:

Product use optical scanning measurement method, Non-contact measurement method measures the objects of diameter, width and thickness, ovality. Product is high-precision, 0.0001mm resolution. Product is suitable for wire on-line measurement and monitoring, quality inspection etc. Instrument has external access interface can be accessed DPM series displayer and controller, PLC or computer.



2LGD-02 Product application: suitable for the following industries diameter measurement, the width and thickness measurement, ovality measurements.

lWire industry: enameled wire, copper wire measurement. Nylon wire, plastic wire, textile wire measurements.

lCutting line industry: cutting line measurements.

lWire-drawing industry: Micro wire drawing, tungsten measurements, molybdenum wire measurement etc.

lOptical fiber Industry: Fiber measurements, transparent material measurements.

lHigh-class electronic cable industry, audio/video cable industry.

lOther industries: on-line measurement, off-line measurement, quality inspection, other specialized measurements.




3, Principle of measurement,

The laser beam emitted from the semi-conductive laser “a” is deflected by the fast rotating octoangular prism “b” driven by the motor “c”. After scanning and passing the lens “d”, the beam becomes a beam of parallel light running through the measurement zone (gate). If the object to be measured “e” is located in the gate, it will block part of the parallel light. After the parallel light is transmitted through the focusing lens “f”, the blocked part will be transformed into a low level electric signal while the unblocked part will be transformed into a high level electric signal by the photoelectric tube “g”. The outer diameter of the tested object in the direction of the scanning light may be calculated from the scanning time of the low-level electric signal.
