Laser Diameter Measuring Device

Laser Diameter Measuring Device Key Functions

 

• Dimensional Accuracy Control

Continuously monitors the pipe's outer diameter and ovality, ensuring compliance with national standards and customer specifications.

• Material Savings

Uses closed-loop control to hold dimensions at the lower tolerance limit, preventing overuse of raw material.

• Scrap Reduction

Detects dimensional deviations immediately and triggers alarms, helping to avoid the production of non-conforming batches.

 

Laser Scanning Diameter Gauge

• Principle: A rotating optical screen scans the object; the system calculates the diameter from the time the laser beam is blocked by the object.
• Features: Non-contact measurement with micron-level accuracy and fast response, well suited for high-speed production lines. Bi-directional models measure outer diameter and out-of-roundness simultaneously in both X and Y axes, overcoming the limitation of single-axis gauges that cannot detect ovality.
• Suitable diameters: Small to medium sizes.

Optical (CCD) Diameter Gauge

• Principle: Uses a telecentric optical system and line-scan CCD imaging. A collimated light beam passes through the receiving lens and forms an electronic image on the CCD array. The outer diameter is calculated by measuring how the pipe edges block the light.
• Features: No moving parts, so there is no wear-related error. Easy maintenance and excellent long-term stability. The collimated light method greatly reduces errors from lateral movement, making it particularly advantageous for measuring fast-moving objects.
• Suitable diameters: Works for diameters from 0.1 mm upward.

Ultrasonic Thickness Gauge

• Principle: Based on ultrasonic pulse reflection. A probe sends out pulses that reflect off the pipe wall surface; the wall thickness is determined by calculating the time-of-flight difference. For small-diameter pipes, high-frequency focused immersion probes are often used to concentrate the sound into a narrow beam, effectively transmitting acoustic energy into the pipe wall.
• Features: Non-contact, high-accuracy, real-time in-line wall thickness monitoring.
• Applications: In-line wall thickness inspection for metal and plastic pipes (e.g., PVC, PE), as well as corrosion monitoring on oil and gas pipelines.

• Significant material savings

Precise tolerance control reduces raw material consumption.

• Dramatically higher pass rates

Real-time monitoring and automatic correction boost product acceptance rates.

• Less manual intervention

Automated dimensional control lowers operator skill requirements and minimizes human error.

• Stronger competitive edge

Consistent dimensional accuracy and a comprehensive traceability system enhance market competitiveness.
