style="text-indent:25px">防爆浮球液位儀表開關，也稱為防爆浮球液位儀表控制器。它是專門為性環(huán)境中使用而設計制造的液位控制儀表，液位儀表開關是基于浮力原理和杠桿原理設計的，當容器內(nèi)液位發(fā)生變化時，浮球的位置將隨液位的變化而變化，浮球的這種位移將通過杠桿作用于微動開關，進而由微動開關產(chǎn)生開關信號。防爆浮球液位開關可以大范圍的適用于石油、化工、電力、冶金、食品、制藥、造紙等行業(yè)中。它能夠?qū)崿F(xiàn)對各類容器內(nèi)液位的制動報警和控制。</p><p

2.變浮力式液位計原理:它根據(jù)浮簡在液體內(nèi)浸沒的深度不同而所受浮力不同來測量液位，如浮筒式液位計，可用來測高溫、高壓介質(zhì)的液位。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="自貢液位儀表哪家好,液位儀表"
