flow meter scale using information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Changzhou LiangBang instrument design and manufacture of the intelligent electromagnetic
flowmeter is based on a standard manufacturing system and development, its advanced design concepts to ensure the high precision and high reliability of the product, compared with the old electromagnetic flowmeter, it has high precision, measurement.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is to find the electromagnetic flow meter scale using CLP article details the cause of magnetic loss.
City design and manufacture of the intelligent electromagnetic flowmeter is based on a standard manufacturing system and development, its advanced design concepts to ensure the high precision and high reliability of the product, compared with the old electromagnetic flowmeter, it has high measurement precision, reliability, good stability, complete function, long life and other advantages.
Electromagnetic loss of electromagnetic flowmeter is a variety of reasons, the interference may exist around magnetic field and produce loss, may also be caused by the structure of the flow meter itself interference signal transmission speed, whatever the reason, in general, electromagnetic loss of electromagnetic flowmeter has the following several forms: 1, metal measuring tube eddy current loss of excitation power supply frequency is higher, the stronger the magnetic field intensity, the longer the magnetic field of the axial length and measure the tube diameter, wall thickness is thicker, the greater the eddy current is bigger, the greater the eddy current loss and magnetic induction strength lags behind that of the magnetic field current phase Angle.
2, magnetic hysteresis loss hysteresis loss is caused by hysteresis characteristics of magnetic materials.
Coil is connected to alternating current (ac), due to the magnetic hysteresis phenomenon, phase lag phase than current certain Angle (
Hysteresis Angle)
。
When did not reach saturation of the magnetic induction intensity, magnetic hysteresis loss was small.
Therefore, electromagnetic flowmeter using high magnetic permeability of magnetic yoke, core electrical silicon steel sheet, silicon steel sheet rolling direction zui the good and the magnetic field lines in the same direction, in this way, hysteresis losses fall greatly, can be neglected.
The eddy current loss in the yoke, eddy current loss yoke should adopt high magnetic permeability, low electric rate sheet, should be insulated between each piece, can reduce the loss, usually for dozens of Hertz mains frequency, the thickness of the silicon steel sheet is 0.
25 ~ 0.
5 mm can make the eddy current loss does not exceed the allowable value.
The development of instrument and meter industry, instrument and meter industry technical breakthroughs cannot leave the instrument manufacturer's support and effort.
Our company as a traffic instrument manufacturer, we strive to break through the bottleneck, independent research and development of new technology, learning process and experience of the flow meter instrument manufacturers at home and abroad, to complement each other for me to use.
The introduction of professional production equipment, design more new products, meet the needs of more customers.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
