The Maintenance of the Magnetostrictive Level Transmitter

The magnetostrictive level transmitter is a kind of linear device with the property of metal induction, which transforms various measured physical quantities into electrical quantities when it works. There are several aspects that are very important when using the magnetostrictive level transmitter, otherwise it is easy to suffer from damage. The following is a brief introduction to the maintenance of the magnetostrictive level transmitter, which will naturally reduce the damage on the product.

First of all, the magnetostrictive level transmitter will easily suffer from line aging, as well as wear and tear due to the mechanical movement. At the same time, it is also easy for a lot of impurities water mixture and oil to enter into the transmitter in the process of use, which will have a very serious impact on the contact resistance of the brush. A situation that often occurs is that the output data of transmitter is not very stable, and the number on the digital display will frequently jump.

Secondly, there is the issue of power supply. The magnetostrictive level transmitter that does not require autonomous power supply should be excluded here. If the power capacity becomes smaller, then the movement of the sol will lead to changes or fluctuations in the display of the mould closing electronic ruler, and there may also be fluctuations in the injection magnetostrictive level transmitter resulted by the mould closing movement, leading to a relatively large error in the measurement results. If the driving power of the solenoid valve and the driving power of the magnetostrictive level transmitter are put together, it will be very easy to have these situations. If the situation is very serious, the voltage fluctuation can be measured even with a multimeter.

Finally, FM interference and the electrostatic interference. To distinguish the signal line of the magnetostrictive level transmitter from the strong wire of the equipment, the magnetostrictive level transmitter shall be equipped with a grounding bracket, and its shell shall be in contact with the ground. In order to check whether there is electrostatic interference in the magnetostrictive level transmitter, you may wish to connect the sealing screw on the magnetostrictive level transmitter and some metal segments on the equipment with the power cord. As long as the connection is made, the electrostatic interference will disappear.
