摘要
液位测量是自动化控制系统中极为重要的关键环节,磁致伸缩液位计是近十年来推出的新产品,具有高精度和高可靠性的特点,在化工中的各种过程罐或者储罐可以有着广泛的应用。在20世纪90年代,将这技术引入了液位和界位测量,也将液位测量水平大幅度提高,进口的磁致的测量精度可以达到±0.25mm,长距离也是同样的指标,分辨率优于±0.1mm。
Liquid level measurement is a very important part in the automatic control system and the magnetostrictive liquid level transmitter is a newly developed product for nearly ten years which is characterized by its high accuracy and high reliability,therefore it is widely used in various tanks or drums in the chemical industry.In the 1 9 9 0s,this technology was introduced into the liquid level and interface level measurement which greatly improved the level of liquid level measurement,the accuracy of the imported magnetostrictive liquid level transmitter can achieve±0.2 5 mm,even for the long distance with a resolution better than±0.1mm.
