继电器产品旗下的分类有很多，比如液位继电器就是旗下的一款虽然它的应用似乎并不是十分广泛，但是根据产品的具体使用特性以及除此之外的功能设计入手看来还是比较具有代表性优势的。那么今天为大家普及的知识就是关于液位继电器的工作原理以及更进一步关于基础板块信息介绍。有意向了解购置的朋友不妨参考实际具体情况进一步帮助决定可行方案。
一、液位继电器的工作原理
液位继电器是控制液面的继电器。这是一个继电器内部有电子线路。利用液体的导电性。当液面达到一定高度时继电器就会动作切断电源。液面低于一定位置时接通电源使水泵工作。达到自动控制的作用。自动控制由传感器和控制执行机构组成。液位控制器的传感器一般是导线。利用水的导电性。水的导电性较差，不能直接驱动继电器。所以要有电子线路将电流放大，以推动继电器工作。简化的话是这样!线分高低中三线,高为水位溢出点,自由控制水位高度,水位到此自动停止,低为点为自动加水点,水位在这个点时自动启动加水装置.中线为常触点
二、液位继电器探头介绍
液位上下带动浮子上下动，再通过浮子内部的磁铁石干簧管闭合或开启，给出一个开关信号。24V的一个液位控制点一般都有3个接线柱：一对常开和一对常闭;220V的一般都只有一对常开触点
三、继电器介绍
继电器(英文名称：relay)是一种电控制器件，是当输入量(激励量)的变化达到规定要求时，在电气输出电路中使被控量发生预定的阶跃变化的一种电器。它具有控制系统(又称输入回路)和被控制系统(又称输出回路)之间的互动关系。通常应用于自动化的控制电路中，它实际上是用小电流去控制大电流运作的一种“自动开关”。故在电路中起着自动调节、安全保护、转换电路等作用。
上文为大家介绍的知识有很多，具体包括的是液位继电器的工作原理以及方式方法，除此之外关于继电器产品的基础板块也进行了一个普及分析。由此我们得知对于有意向发挥产品最大效果的朋友而言需要着重加以学习的内容，并且对于部件的参数特性也有了一个相对而言更加详细细致的了解。由此大家可以参考市面上的产品进一步推选出值得信赖的机子。
