The magnetic flap level gauge measures the water level in real time based on the principle of the connector and the magnetic combination. The magnetism can directly know whether the instrument is working normally. In practical applications, if the magnetic counter-board water level gauge has a component phenomenon, it cannot be used normally. So, what is the reason for self-overturning the degaussing device of the water level gauge? What should I do if there is a component phenomenon in the magnetic flip-board water level gauge?1. Reasons for the demagnetization of the magnetic flap level gaugeThe self-injured person of the self-overturning water level gauge has self-clearing phenomenon during use, resulting in the failure of the self-overturning water level gauge. Generally speaking, the main reasons for the self-reversing plate water level gauge degausser are as follows: 1. The remanence of the hard magnetic material is less than the coupling threshold. As time goes by, affected by magnetic factors, as time goes by, the residual magnetism of hard magnetic materials may appear to be less than the coupling threshold. 2. High-performance hard magnetic materials with hydrogen embrittlement. 3. The operating temperature is higher than the Curie temperature of hard magnetic materials.Magnets are magnetic because some small circuits inside the object (for example, long-term placement of non-magnetic iron blocks in a certain magnetic field, etc.) have obtained a certain arrangement, and the total magnetic field strength in one direction is greater than the other.The Curie temperature was discovered and named by Madame Curie. Madame Curie found that high temperature will aggravate the molecular motion inside the magnet, disturb the internal molecular arrangement, and make the magnet lose its magnetism. According to Madame Curie’s discovery, people call the high-temperature drop-out point of a magnet the Curie temperature of the magnet.Generally speaking, magnetic materials have a critical temperature Tc. Above this temperature, the violent thermal motion of atoms at high temperatures leads to disorderly arrangement of the atomic magnetic moments. Below this temperature, the atomic magnetic moments are aligned, causing spontaneous magnetization, and the object becomes ferromagnetic. Too high temperature may cause magnetic levitation or magnetic flaps of magnetic components. Therefore, in order to avoid the phenomenon of high-temperature components, the user must clarify the temperature of the medium to the instrument manufacturer when purchasing the product to ensure that the high-temperature father and son to be selected meet the working conditions.2. Degaussing treatment of magnetic flap level gaugeFor the magnetic removal of the magnetic flip-plate level gauge, the following operations are usually required to deal with the magnetic removal phenomenon of the magnetic flip-plate level gauge:a) In terms of design, suitable hard magnetic materials should be selected. For example, when selecting magnetic materials, the Curie temperature should be more than 20% higher than the operating temperature, and the remaining magnetic properties after 5 years should be guaranteed to exceed the threshold.b) In terms of production, the following matters should be paid attention to when processing magnetic levitation:1. Charge the inert gas (such as argon) in the magnetic levitation.2. In the production and processing stage of the product, when welding (argon arc welding), cooling measures should be taken to ensure that the temperature of the magnetic levitation magnetic material does not exceed the Curie temperature of the magnetic material.c) From the perspective of usage, the user must:1. Select the appropriate model when placing an order, so that the operating temperature does not exceed the nominal temperature of the magnetic reflector water level gauge.
2. During use, always observe the use of the magnetic flip-board water level gauge (whether it works normally), and pay attention to the actual temperature of the recording medium.
