Causes of Magnetic Grating Ruler Demagnetization

The magnetic grating ruler is a common measuring tool that uses magnetic markings and read heads for length measurement. During use, demagnetization may occur, reducing measurement accuracy and stability. What causes this demagnetization?

First, external magnetic fields can cause demagnetization. Strong magnetic sources in industrial sites or during transport and installation may interfere with the ruler and lead to loss of magnetization.

Second, the ruler's own material or manufacturing quality may cause instability. Poor materials or manufacturing processes can make the magnetic properties unstable and prone to demagnetization.

Additionally, vibration or mechanical shock during operation can contribute to demagnetization. It is important to avoid strong impacts and provide stable mounting.

Overall, demagnetization can result from external magnetic interference, material or manufacturing defects, and mechanical stress. Regular inspection, proper handling, and choosing high-quality products help reduce the risk of demagnetization.
