ZB-20F-450料位開關(guān)產(chǎn)品介紹（中文）
ZB-20F-450阻旋式料位開關(guān)是一種用于固態(tài)物料（包括粉狀、粒狀、塊狀等）的物位控制設(shè)備。該產(chǎn)品采用永磁電機(jī)帶動不銹鋼葉片旋轉(zhuǎn)的工作原理，當(dāng)被測物料上升至葉片位置時，葉片受阻停止轉(zhuǎn)動，通過傳動機(jī)構(gòu)觸發(fā)開關(guān)信號并切斷電源；物料下降后，葉片在彈簧拉力作用下恢復(fù)旋轉(zhuǎn)狀態(tài)。產(chǎn)品具有密封設(shè)計，防護(hù)等級達(dá)到IP65，可適應(yīng)-10℃至80℃的工作環(huán)境（特殊定制可達(dá)400℃），適用于水泥、冶金、煤炭、飼料等行業(yè)。其特點(diǎn)包括：全密閉結(jié)構(gòu)可在戶外使用；油封設(shè)計防止粉塵滲入；五檔靈敏度調(diào)節(jié)裝置可適應(yīng)不同比重物料；過載保護(hù)功能可避免外力損壞電機(jī)；304不銹鋼材質(zhì)確保耐腐蝕性。安裝方式支持側(cè)裝或頂裝，法蘭或螺紋連接，葉片形狀可根據(jù)物料特性選擇。1312
ZB-20F-450 Level Switch Product Introduction (English)
The ZB-20F-450 rotary paddle level switch is designed for solid material level detection, including powders, granules, and bulk materials. Its working principle involves a permanent magnet motor driving a stainless steel paddle. When material rises to the paddle position, the rotation resistance triggers a switch signal and cuts off the power supply; as material level drops, the paddle automatically resumes rotation via spring mechanism. Featuring IP65 protection and operating temperature range of -10℃ to 80℃ (customizable up to 400℃), this device suits industries like cement, metallurgy, coal, and feed processing. Key characteristics include: fully sealed housing for outdoor use; oil-sealed design preventing dust ingress; five-stage sensitivity adjustment for materials with different densities; overload protection safeguarding motor; and SUS304 stainless steel construction. Installation options include side-mounted or top-mounted configurations with flange/thread connections, while paddle shapes can be selected based on material properties. The product demonstrates reliable performance in monitoring material height limits, particularly for conductive materials or substances with variable dielectric properties.3726
產(chǎn)品技術(shù)參數(shù)補(bǔ)充說明
該設(shè)備電源支持220VAC/110VAC/24VAC/24VDC多種規(guī)格，功率消耗為3W，觸點(diǎn)容量8A/250VAC（單刀雙擲）。標(biāo)準(zhǔn)葉片轉(zhuǎn)速為1rpm（逆時針），旋轉(zhuǎn)力矩1N·m，適用物料比重≥0.4g/cm³。電氣接口采用M20×1.5規(guī)格，過程連接可選擇JIS 2-1/2法蘭或螺紋。針對特殊工況，可提供軸保護(hù)型設(shè)計，延長設(shè)備在磨損性物料中的使用壽命。產(chǎn)品采用機(jī)電分離結(jié)構(gòu)，維護(hù)時無需拆卸整體，簡化了檢修流程。在食品加工或高粉塵環(huán)境中，其防潮防塵特性表現(xiàn)良好，且扭力彈簧的拉力可根據(jù)物料比重靈活調(diào)整，確保檢測準(zhǔn)確性。31113
Application Scenarios and Features
This level switch excels in monitoring bulk solids in silos, hoppers, and conveyors, especially for materials with changing physical properties (humidity, dielectric constant) or high dust conditions. The clutch mechanism automatically disengages when the paddle encounters excessive load, preventing motor damage. Its compact design allows easy installation in confined spaces, while the separable probe and controller design facilitates maintenance without process interruption. The device is commonly applied in: chemical plants for plastic pellet detection; power plants for fly ash level control; grain storage systems; and steel mills for raw material inventory management. The vibration-resistant construction ensures stable operation in industrial environments, and the visible paddle rotation status aids in quick troubleshooting. Customizable paddle lengths (100-800mm) and materials accommodate various vessel configurations.122126

一、產(chǎn)品簡介：
阻旋開關(guān)是用于固態(tài)物料（包括粉狀、塊狀、粒狀、膠狀等）的物位控制器。它具有密封性好、過載能力強(qiáng)、輕便易裝、輸出觸點(diǎn)容量大等特點(diǎn)。針對不同比重的物料可通過調(diào)彈簧的拉力來實(shí)現(xiàn)，其接觸物料部分全為不銹鋼材料。阻旋開關(guān)在化工、塑料、水泥、制藥、飼料、食品等行業(yè)得到了廣泛的應(yīng)用。
二、工作原理
電機(jī)帶動葉片旋轉(zhuǎn)，當(dāng)被側(cè)介質(zhì)到達(dá)葉片位置時，葉片手足停止轉(zhuǎn)動，從而觸動后面的微動開關(guān)輸出開關(guān)信號，當(dāng)被測介質(zhì)下降離開葉片時，葉片在彈簧的作用下恢復(fù)原位繼續(xù)轉(zhuǎn)動。彈簧的拉力可根據(jù)所測介質(zhì)的比重進(jìn)行調(diào)整，物料比重大時彈簧調(diào)整到*強(qiáng)，反之調(diào)至*弱。
