QINSUN interpretation simply solves the demagnetization phenomenon of magnetic flap level gauge –

The solution to the demagnetization phenomenon of the magnetic flap level gauge can be divided into the following aspects:
A. From the design point of view, it is necessary to choose suitable hard magnetic materials. For example, choose a magnetic material whose Curie temperature is 20% higher than the service temperature and ensure that the residual magnetism exceeds the critical value after five years.

B. From the point of view of production, the following points should be considered when processing magnetic floats:

1. When welding (argon arc welding), it is necessary to take special cooling measures to prevent the temperature of the magnetic material of the magnetic float from exceeding the Curie temperature of the magnetic material.
2. The magnetic float is filled with inert gas (such as argon);
C. From the perspective of use, the user should proceed asfollows:
1. Choose the correct one when ordering. 2. When using, it is necessary to observe the use of the liquid level gauge at all times (whether in normal service), and record the actual state of the fluid. Temperature (I\'ve seen cases where the actual operating temperature is often higher than the temperature listed on the datasheet, and the person who designed the datasheet may have overlooked some factors).
