Causes and Solutions for Magnetic Scale Zero-Point Loss

Magnetic scales are high-precision displacement measurement tools widely used in industrial automation and CNC equipment. Sometimes users experience zero-point loss, which affects accuracy and production efficiency. This article discusses common causes and solutions.

1. Improper installation

Alignment between the magnetic scale and the read head is critical. Misalignment during installation can cause measurement errors and zero-point drift. Follow the manufacturer's installation guide carefully.

2. Signal interference

External electromagnetic interference or mechanical vibration can affect signal stability. Where strong electromagnetic sources or vibration exist, use isolation measures to protect the signals.

3. Temperature variation

Thermal expansion or contraction changes dimensions and affects readings. In environments with large temperature swings, consider using devices with temperature compensation or maintain a more stable temperature.

4. Wear or aging

Long-term use may lead to wear or aging of components, affecting performance and zero-point accuracy. Regular inspection and maintenance, and replacement when necessary, help preserve accuracy.

5. Power issues

Stable power is required for normal operation. Unstable power can cause processing errors and zero-point loss. Use quality power supplies and monitor power stability regularly.

6. Software settings

Incorrect parameters in the control software can also affect zero-point. Regularly check and adjust software settings according to actual conditions.

Conclusion

Zero-point loss affects productivity and quality. Diagnose installation, environment, maintenance and software settings to resolve issues. For complex problems, consult professional technicians to restore optimal operation.
