SUS304/316 zui高為 200 ℃。2 、壓力：塑膠類浮球耐壓較大 5kg/cm2 ， SUS 浮球耐壓zui大 30kg/cm2 。3 、粘著：應選用球大、比重小的浮球才能克服液體表面張力。4 、化性： PVDF 塑膠材質適用于酸堿場所， H2SO4 硫酸如有溫度考慮時應選用 PVDF 。 PP 塑膠材質適用于 HCl 鹽酸場所。 NBR 橡膠適用于油環(huán)境。 5 、油精：應使用不銹鋼金屬材質。6 、比重：浮球比重 SG 必須小于被測液體，否則浮球浮不起來。7 、防護防爆等級：可根據客戶要求選擇各種接線盒，接線盒規(guī)格齊全，有塑膠、鋁合金、不銹鋼防爆型，防護等級可達 IP-65 以上。8 、電氣開關形式：接點容量 50W/250VACSPST 或 40W/250VACSPDT 。9 、安裝連接方式：接續(xù)法蘭有 JIS ， DIN ， ANSI

style="text-indent:25px">電纜式液位開關接線注意事項：在與水泵相連的時候需要在中間增加一個交流接觸器或者中間繼電器做為過載，防止浮球開關因為電流超高等原因而燒壞。另外就是對于材質的選擇也需要了解清楚，選擇到適合自己環(huán)境的電纜浮球液位開關。防爆液位開關的三種形態(tài)： 1、根本型，根據浮力原理，浮子在丈量管內隨液位的升降而上、下移動，浮子內的持久磁鋼通過耦合效果，驅動紅、白色翻柱翻轉180°，液位上升時翻柱由白色轉為紅色，降低時由紅色轉為白色，然后完成液位指示。2、電遠傳，在浮子液位計上裝置變送器，通過浮子上下移動，經磁耦合效果使導桿內丈量元件順次動作，取得電阻信號改變，轉換成0～10mA或4～20mA的標準信號輸出，與顯現外表或計算機連接，到達遠傳意圖。 3、上下限開關輸出，在液位計立管上由用戶設定上、下限方位裝置操控器，操控器內帶有自保持效果的舌簧開關，使用磁性浮子隨液位移動使簧片開關動作時，完成報警或限位操控。電纜浮球液位開關哪里買</p><p
