Abstract: There are many reasons for the electromagnetic loss of electromagnetic flowmeter meters. The information is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. There are many reasons for the electromagnetic loss of the electromagnetic flowmeter. There are many reasons for the electromagnetic loss of the electromagnetic flowmeter. It may be caused by the interference of the surrounding magnetic field, or the structure of the flowmeter itself may cause the interference of the signal transmission speed, no matter what the reason is. ,one. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the electromagnetic loss of electromagnetic flowmeters for various reasons. There are many reasons for the electromagnetic loss of the electromagnetic flowmeter. There are many reasons for the electromagnetic loss of the electromagnetic flowmeter. It may be caused by the interference of the surrounding magnetic field, or the structure of the flowmeter itself may cause the interference of the signal transmission speed, no matter what the reason is. , In general, the electromagnetic loss of electromagnetic flowmeter has the following forms: Hysteresis loss Hysteresis loss is caused by the hysteresis characteristics of magnetic materials. After the coil is supplied with alternating current, due to the hysteresis of the magnetic material, the phase of the magnetic flux lags behind the current phase by a certain angle (hysteresis angle). When the magnetic induction in the iron core does not reach saturation, the hysteresis loss is very small. Therefore, the yoke and iron core of the electromagnetic flowmeter are made of electrical silicon steel sheets with high magnetic permeability. The eddy current loss yoke in the eddy current loss yoke should be made of sheets with high permeability and low electromotive force, and each sheet should be insulated to reduce losses. Usually, for the commercial power frequency of tens of hertz, the thickness of the silicon steel sheet is 0.25 ~0.5mm can make the eddy current loss not exceed the allowable value. The higher the frequency of the eddy current loss excitation power supply in the metal measuring tube, the stronger the magnetic field strength, the longer the axial length of the magnetic field, the larger the diameter of the measuring tube and the thicker the wall thickness, the greater the eddy current and the greater the eddy current loss. The phase difference angle at which the magnetic induction lags behind the magnetic field current is also larger.
