激光機(jī)流量開關(guān)
流量開關(guān)---.jpg)
激光機(jī)系列流量開關(guān), 是專為清潔液體或有腐蝕性的液體流量控制和監(jiān)控開發(fā)的, 廣泛用于超純凈水系統(tǒng), 高精密分析測試系統(tǒng).整體采用不銹鋼材質(zhì)制成,NPT1/4,3/81/2"管螺紋,安裝簡單方便.流量設(shè)定值可根據(jù)用戶要設(shè)定.
活塞式流量開關(guān)由塔簧、帶磁性環(huán)活塞等部件組成，當(dāng)有液體流動時(shí)，活塞向前移動，活塞中磁元件經(jīng)磁耦合控制干簧繼電器的動作。當(dāng)有液體或氣體流動，小于某設(shè)定值時(shí)，輸出干結(jié)點(diǎn)信號。專門為冷卻系統(tǒng)設(shè)計(jì)，也適用于某些化學(xué)應(yīng)用及各種冷卻應(yīng)用。
