style="text-indent:25px">全自動(dòng)洗衣機(jī)中一般采用的液位開關(guān)就是壓力式水位開關(guān)，它裝在洗滌缸的上部，它有一根下端開口的氣管通到缸底，進(jìn)水時(shí)管里的空氣被封閉在里面出不來，就形成比外界稍高的壓力。水位越高壓力越高，這樣根據(jù)壓力就可間接測知水位。而壓力的測量仍然用彈性元件，靠元件的變形帶動(dòng)觸點(diǎn)完成通斷動(dòng)作。這種測液位的方法叫做“靜壓法”，在工業(yè)中用的不少。浮球式液位開關(guān)的特點(diǎn)是有一個(gè)帶桿的浮球，隨著液位的變化，浮球聯(lián)動(dòng)的桿隨著變化，從而控制開關(guān)的閉合。工業(yè)上很早就利用浮子測量水塔中的水位了。單探頭液位開關(guān)哪家正規(guī)音叉式液位開關(guān)是一種新型的液位開關(guān)。</p><div

1、電容式液位開關(guān)，電容式液位開關(guān)是選用偵測液位改變時(shí)所導(dǎo)致的細(xì)小電容量(一般為PF)差值改變，并由**的ADA電容檢查芯片進(jìn)行信號(hào)處理(能夠輸出多種信號(hào)通訊協(xié)議，如：IO,BCD, PWM,UART,IIC＆#823;)，然后檢查出水位，并輸出信號(hào)到輸出端。2、浮球式液位開關(guān)，浮球式液位開關(guān)的特點(diǎn)是有一個(gè)帶桿的浮球，跟著液位的改變，浮球聯(lián)動(dòng)的桿跟著改變，然后操控開關(guān)的閉合。工業(yè)上很早就使用浮子丈量水塔中的水位了。浮球液位開關(guān)分為模擬輸出型和開關(guān)量輸出型兩種。模擬量輸出型：磁性浮球隨液位的改變不斷觸發(fā)檢查桿中的磁簧開關(guān),使得傳感器的總電阻發(fā)生改變，該信號(hào)被變送器轉(zhuǎn)換成標(biāo)準(zhǔn)4＆#82320;mA信號(hào)輸出。開關(guān)量量輸出型：液位上升或降低時(shí)，股動(dòng)不銹鋼磁性浮球上下移動(dòng),浮球觸發(fā)檢查桿中的的磁簧開關(guān)，宣布信號(hào)。3、電磁式液位開關(guān)，開關(guān)量輸出型。液位上升或降低時(shí)，股動(dòng)不銹鋼磁性浮球(浮塊)上下移動(dòng)，至報(bào)警方位及時(shí)報(bào)警輸出。并可選溫度開關(guān)量輸出。</p><p
