Principle Principle




The laser beam is emitted from a semiconductor laser, reflected by a multi-faceted mirror and a plane mirror, and then passes through a collimating F(θ) lens to scan the measured object in parallel alignment. The shadow of the beam formed by the measured object is focused through the receiver lens and converted into an electronic signal. The size of the measured object is calculated based on the time taken for the beam to be blocked and form a shadow.

Common surface defects of flat wires







    The flat wire diameter gauge, with customizable high-speed sampling frequency, provides an efficient and cost-effective solution for detecting surface defects in flat wire during online production. When defects such as bubbles formed during the varnishing process of flat enameled wires occur, the LSG-1020XYF gauge can accurately detect and record the bubble's position, triggering an alarm to ensure product quality and enhance production efficiency.

    Additionally, through the software system, alarm signals can be triggered, and defect positions, sizes, and types (X direction: concave, convex; Y direction: concave, convex) can be recorded.









Intelligent Software System











1.Real-time Data Display: Records and displays the outer diameter measurement values along with the variation curve, allowing for historical data retrieval.


2.Out-of-tolerance Alarm: Allows users to set tolerance parameters for outer diameter based on production processes. When measurements exceed the set limits, the system triggers an alarm and marks the deviation on the diameter curve.


3.Defect Detection and Positioning: Records the number of concave and convex defects, and marks defect locations based on preset speed, ensuring efficient monitoring and quality control.
