电磁流量计由电磁流量变送器和电磁流量转换器组成。我厂于五十年代末期在上海热工仪表研究所(即上海工业自动化仪表研究所)的指导下研制成功了小口径的电磁流量计。至今已有20余年的历史,规格品种亦有很大的发展,基本形成了一个系列。口径从25毫米扩展至1200毫米,衬里亦有耐蚀、耐磨等品种。由于采用了非均匀磁场结构,仪表外型尺寸、重量等已大量的减小,价格亦已下降。当前已在各行各业广泛采用。 1、工作原理(简要) 变送器是根据法拉第电磁感应原理工作的。
Electromagnetic flowmeter by the electromagnetic flow transmitter and electromagnetic flow converter. I plant in the late fifties in Shanghai Institute of thermal instrumentation (ie, Shanghai Institute of Industrial Automation Instrumentation) under the guidance of the successful development of a small diameter electromagnetic flowmeter. So far, more than 20 years of history, specifications and varieties also have great development, the basic form of a series. Diameter from 25 mm to 1200 mm, the lining also has corrosion-resistant, wear-resistant varieties. As a result of a non-uniform magnetic field structure, instrument size, weight, etc. have been greatly reduced, the price has dropped. Currently widely used in all walks of life. 1, the working principle (briefly) The transmitter is based on Faraday’s principle of electromagnetic induction work.
