　　音叉物位计是一种新型的物位开关，也常被称为音叉式物位计或者音叉式物位控制器，它是利用音叉振动的原理设计制作的。今天Ameya360电子元器件采购网将给大家进行介绍。

音叉物位计的原理 音叉物位计的特点

　　一、音叉物位计的原理

　　音叉式物位控制器的工作原理是通过安装在音叉基座上的一对压电晶体使音叉在一定共振频率下振动。当音叉与被测介质相接触时，音叉的频率和振幅将改变，这些变化由智能电路来进行检测，处理并将之转换为一个开关信号。

　　二、音叉物位计的特点

　　音叉物位计采用国外的新技术和原装进口芯片，具有使用寿命长、性能稳定、安全可靠等优点，以及适应性强（被测介质不同的电参数、密度对测量均不产生影响）、不需调校（无论测量何种介质都不需要现场调校）和免于维护等特点，广泛应用于冶金、建材、化工、轻工、粮食等行业中物位的过程控制。

　　三、音叉物位计应用场合

　　HMT系列音叉式物位控制器，它不受泡沫、涡流、气体的影响，适用于各种料仓固体物料料位以及各种容器内液位的定点报警或控制。

　　固体物料： 能自由流动的中等密度的固体粉末或颗粒。

　　粉煤灰、水泥、沙子，石粉、塑料颗粒、盐、糖等。

　　液体介质： 具有爆炸性和非爆炸性危险的液体，腐蚀性液体（酸、碱）高粘度液体 水、酸、碱、泥浆、纸浆、染料、油类、牛奶、酒类、饮料等。

　　为了适合不同场合的应用，产品还包括高温型、加长型、防腐性等。请根据需要选择产品类型。
