在工业生产中,有着大量的储液槽,特别是在化学工业和冶金工业中,大大小小的储液槽更多,要实现集中监视、集中操作,以减少生产人员,提高劳动生产率,就必须把这些液槽中液面的变化转换成便于远传的信号,即设置远传液面计。在当今的工业生产中,用有多种液面计,利用电的原理有:滑轮式、电容式及电感式多种,而且各有长短之处。就我们所知,电感式液面计以前也出现过,但仅用于某一水位的报警,而不能用于变化范围较大的液面的连续测量,故这种电感式液面计用处极其有限。最近我们试制了一种新的电感式液面计,现介绍于后。
In industrial production, there are a large number of reservoirs, especially in the chemical and metallurgical industries where there are more and more large and small reservoirs. In order to achieve centralized monitoring and centralized operation so as to reduce the number of production personnel and increase labor productivity, The liquid level in these tanks must be converted into a signal for remote transmission, ie a remote gauge is provided. In today’s industrial production, there are a variety of liquid level meter, the principle of the use of electricity are: a variety of wheel-type, capacitive and inductive, but also have their own length and breadth. As far as we know, inductive level gauge has appeared before, but only for a certain level alarm, but can not be used for continuous measurement of a wide range of changes in the liquid level, so the use of inductive level gauge extremely limited. Recently, we trial a new type of inductive liquid level meter, are introduced later.
