ULC 系列磁致伸缩液位仪Magnetostrictive Level Gauge

基本原理：

一触发线圈周期性发出短暂电流“询问”脉冲，同时产生一个磁场沿波导线传播，磁性浮子随液位升降沿导杆上下移动，由于磁场的相互作用，于是产生短暂的扭矩应力。该应力返回并转换成电脉冲，从发出“询问”脉冲到接收“返回”脉冲的时间即是对应于液位的变化。

性能特点：

● 测量范围0 -18m ；

● 测量精度高： U+ U1mm 或0.3%F*S （电流输出型）分辨力：≯0.3mm ；

● 高可靠性；

● 多参数测量：液位，界位，温度，容积，密度，重量及限位报警；

● 易安装，使用寿命长；

● 外壳防护IP65 ；

● 防爆标志：Exia(ia) II BT4, Exd II BT4

用途： 适用于石油，化工，电力，轻纺，食品，制药，水处理系统等行业的液位，界面进行连续测量与控制。
