Principle Principle




Transmitter Side: The high-intensity green LED emits high-power green light, which is collimated and parallelized by the collimating lens. When the green light hits the measured object, it casts a shadow.
Receiver Side: The telecentric optical system projects the shadow of the measured object onto the CCD image sensor. In the high-speed linear CCD, a precise image of the measured object is formed. The image is then processed and calculated by the digital edge detection processor to obtain accurate measurement dimensions.

Application Scenario
Understanding the product’s application mode helps in selecting the most suitable product, improving work efficiency and performance.
  • Unaffected by wire oscillation
    10KHz sampling frequency with adaptive anti-shake algorithm ensures precise outer diameter measurement and captures even the smallest changes during high-speed production.
  • Custom Tooling & Guide Wheel Measurement
    Custom tooling and ceramic-coated guide rollers reduce friction and minimize wire damage. The design ensures compatibility with existing equipment, crucial for precise width and thickness detection in flat wire measurement.
  • Surface defect detection
    The LCG series, with 10KHz frequency, measures outer diameter and detects surface defects in one device, cutting costs.
Technical Features

    The LCG series uses a CCD telecentric optical imaging system, enabling faster sampling of the target's outer profile with a sampling frequency up to 10KHz. The high sampling rate, combined with a high-performance DSP processor, ensures stable data processing. This combination achieves accuracy and stability in single measurements, providing stable results in a very short time. It also analyzes outer diameter variations and detects surface defects, including size of protrusions and indentations.

    Main applications: ultra-fine wires, metal drawn wires, diamond wires, tungsten wires, optical fibers, nylon wires, enameled wires, etc.

































High-speed CCD telecentric imaging optical system









1. High-intensity green LED emits high-power green light.
2. The collimator lens makes the light parallel and collimated for emission.
3. The emitted light strikes the object, causing a shadow.
4. The telecentric optical system projects the shadow onto the CCD image sensor.
5. The accurate shadow image of the object is formed on the high-speed linear CCD.
6. The digital edge detection processor processes and calculates the measurements.

Surface defect detection







    Intelligent software system












The software system works with the measuring instrument, offering real-time communication and these key functions: 


1. Real-time data display: 

Records and shows key parameters like diameter, ovality, and surface defects. It also plots outer diameter trends.



2. Customizable alarms:

Users can set tolerance ranges. The system alerts and logs when measurements exceed limits, recording values and locations for quick corrections.


3. Defect detection and logging:

Records surface defects (e.g., dents, bumps, particles) for quality analysis and traceability.
