英文產(chǎn)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(guān)
阻旋料位開關(guān)產(chǎn)品原理：阻旋料位開關(guān)是一種用于固態(tài)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(jī)帶動(dòng)葉片旋轉(zhuǎn)，當(dāng)被檢測(cè)物料上升至葉片位置時(shí)，葉片轉(zhuǎn)動(dòng)受阻，該阻力通過傳動(dòng)軸傳遞到接線盒內(nèi)的檢測(cè)裝置，檢測(cè)裝置則向外輸出一個(gè)開關(guān)信號(hào)，并切斷電機(jī)電源使葉片停止轉(zhuǎn)動(dòng)。當(dāng)物料下降時(shí)，葉片阻力消失，檢測(cè)裝置便依靠彈簧的拉力恢復(fù)到原始狀態(tài)，葉片恢復(fù)旋轉(zhuǎn)狀態(tài)。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業(yè)得到了的應(yīng)用。
