德國BURKERT數(shù)字式控制器價(jià)格/寶德數(shù)字式流量控制器
德國BURKERT數(shù)字式控制器由次電極式傳感器和二次控制器組成體式測量系統(tǒng)，液位開關(guān)安裝在容器的頂部或容器的壁上，電極插入液體。以單電極供液型控制為列。測量時(shí)，電極上通有交流信號(hào)電壓，當(dāng)液位上升接觸到電極時(shí)，電極間就有交流信號(hào)電流流過從而產(chǎn)生液面信號(hào)，控制板接收到液面信號(hào)后，進(jìn)行整流、濾波、放大等處理，zui后轉(zhuǎn)換成繼電器閉合觸點(diǎn)輸出或標(biāo)準(zhǔn)電流16mA輸出給用戶使用。當(dāng)液位下降離開電極時(shí)，電極間就沒有交流信號(hào)電流流過，控制板接收不到液面信號(hào)，繼電器又恢復(fù)成釋放狀態(tài)或標(biāo)準(zhǔn)電流又回到8mA。因此通過液體與電極接觸與不接觸，繼電器吸合與不吸合或電流大小，就能正確測量出液位高低位置。德國BURKERT數(shù)字式控制器的測量通常是構(gòu)成電容器的個(gè)極板，而另個(gè)極板是開關(guān)的外殼。這個(gè)外殼在測量過程中通常是接地或與設(shè)備的機(jī)殼相連接。當(dāng)有物體移向接近開關(guān)時(shí)，不論它是否為導(dǎo)體，由于它的接近，總要使電容的介電常數(shù)發(fā)生變化，從而使電容量發(fā)生變化，使得和測量頭相連的電路狀態(tài)也隨之發(fā)生變化，由此便可控制開關(guān)的接通或斷開。這種接近開關(guān)檢測的對象，不限于導(dǎo)體，可以緣的液體或粉狀物等。
