The following are the details of the article to find out the reasons for electromagnetic loss during the use of electromagnetic flowmeters. The intelligent electromagnetic flowmeter developed, designed and manufactured by the city is developed based on the standardized manufacturing system. Its advanced design concept ensures the high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy, It has the advantages of strong reliability, good stability, complete functions and long service life. 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. The loss has the following forms: 1. 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 higher the eddy current loss. The larger the current, the larger the eddy current loss, and the larger the phase difference angle of the magnetic induction lag behind the magnetic field current. 2. 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. 3. The eddy current loss yoke in the eddy current loss yoke should be made of sheets with high magnetic permeability and low electromotive force. 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 If it is 0.25~0.5mm, the eddy current loss will not exceed the allowable value. The development of the instrumentation industry and technological breakthroughs in the instrumentation industry are inseparable from the support and efforts of various instrumentation manufacturers. As a flow meter manufacturer, our company strives to break through bottlenecks, independently develop new technologies, learn the craftsmanship and experience of domestic and foreign flow meter manufacturers, and learn from each other's strengths and weaknesses. Introduce professional production equipment, design more new products, and meet the needs of more customers. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Find out the causes of electromagnetic loss during the use of electromagnetic flowmeters'
