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。

This gauge is a precision instrument based
on the magnetostriction technique. It uses electric
technology to carry out level measuring, so it can work
safely and reliably and has a long working life without
abrasion. It is convenient to observe in field with LCD
inside transmitter.
Application:
It can be widely used to measure,
alarm and control level, interface level, temperature on
normal pressure and pressured containers in industry process,
chemical, petroleum, pharmaceutical, food, water treatment,
underground storage of petrol station and etc. It is an
explosion-proof product in accordance with the requirements
of the state explosion-proof standard.
