\rL4660SC超聲波液位計(jì)<\/strong>工作原理由探頭發(fā)出超聲波脈沖，以聲波速度傳播，遇到被測(cè)介質(zhì)表面被反射，部分反射回波被同一探頭接收，轉(zhuǎn)換成電信號(hào)。由于探頭到被測(cè)介質(zhì)表面的距離與從發(fā)射到接受一超聲波脈沖所需的時(shí)間成正比，由此可換算出被測(cè)介質(zhì)的物位高度。<\/span>\r<\/p>\r

\r如果被測(cè)介質(zhì)與探頭距離太近，會(huì)造成反射波與發(fā)射波重疊，無(wú)法正確測(cè)量的這段距離稱(chēng)之為盲區(qū)。盲區(qū)的大小與超聲波脈沖的頻率有關(guān)。<\/span><\/span>\r<\/p>\r
