SLF-30-F-A料位開關
產品概述
SLF-30-F-A是一款專為除鹽水罐等液體介質設計的側裝式不銹鋼浮球液位開關，采用機械式工作原理實現可靠的液位監測與控制。該產品通過304/316不銹鋼材質主體結構和干簧管觸點設計，能夠適應高溫高壓工況，適用于石油化工、食品加工、水處理等多個工業領域。14
工作原理
當液位變化時，浮球在液體浮力作用下沿固定支點上下擺動，帶動末端永磁鋼驅動接線盒內的磁簧開關動作，輸出開關信號（ON/OFF）。這種非接觸式磁耦合傳動方式確保控制部分與液體完全隔離，避免了介質污染和電氣風險。產品支持水平側壁或垂直頂部安裝，通過調整定位塊可靈活設定液位控制范圍。26
結構特點
產品主體采用一體式不銹鋼管密封結構，浮球組件包含環形磁鐵和耐腐蝕不銹鋼浮體。標準配置包含IP65防護等級鋁制接線盒，提供SPDT觸點形式，觸點容量為5A/220VAC。工作溫度范圍覆蓋-20℃至200℃，操作壓力最高可達30Bar，適用于比重≥0.55的各類液體介質。獨特的防塵密封設計和抗震結構有效延長使用壽命。211
應用場景
本產品廣泛應用于發電機設備冷卻系統、化工反應容器、食品工業儲罐及污水處理裝置的液位報警與泵控系統。其衛生級設計符合醫藥行業要求，在存在粘附性介質或易結晶液體的工況中表現優異。典型應用包括：鍋爐給水控制、酸堿儲罐高低位保護、油類儲罐自動供油等場景。615
英文產品描述
The SLF-30-F-A is a side-mounted stainless steel float level switch specifically designed for demineralized water tanks and other liquid media applications. Utilizing a mechanical float mechanism with magnetic reed switch technology, this device provides reliable liquid level monitoring without direct electrical contact with the medium. The 304/316 stainless steel construction ensures corrosion resistance in harsh industrial environments including chemical processing and food production facilities.420
Functional Features
This level switch operates through buoyancy principle - the float moves vertically with liquid level changes, activating hermetically sealed magnetic contacts inside the junction box. The non-intrusive design isolates electrical components from process media, suitable for temperatures ranging from -20°C to 200°C and working pressures up to 30Bar. Standard configuration includes adjustable mounting brackets for flexible level setting, with optional flange connections available. The device outputs SPDT switching signal for pump control or alarm systems.26
Technical Advantages
Manufactured with robust stainless steel housing and food-grade materials, the SLF-30-F-A demonstrates exceptional performance in viscous liquids and high-purity applications. Its maintenance-free operation and simple installation (requiring only single-point fixation) make it ideal for continuous process monitoring. The product s wide compatibility covers diverse media including oils, solvents, and aggressive chemicals when equipped with proper material options.1115
Typical Applications
This float level switch is widely implemented in power plant water treatment systems, pharmaceutical storage vessels, and industrial wastewater management. Common use cases include: automatic pump control in cooling towers, overfill prevention in chemical day tanks, and interface detection in separation processes. The hygienic design meets sanitary requirements for beverage and dairy processing equipment.620
SLF-30-F-A料位開關
阻旋料位開關產品原理：阻旋料位開關是一種用于固態物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器。其利用永磁電機帶動葉片旋轉，當被檢測物料上升至葉片位置時，葉片轉動受阻，該阻力通過傳動軸傳遞到接線盒內的檢測裝置，檢測裝置則向外輸出一個開關信號，并切斷電機電源使葉片停止轉動。當物料下降時，葉片阻力消失，檢測裝置便依靠彈簧的拉力恢復到原始狀態，葉片恢復旋轉狀態。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業得到了的應用。
