SR-80LT Rotary Paddle Level Switch Product Introduction (English)
The SR-80LT explosion-proof rotary paddle level switch is designed for solid material detection in industrial applications such as petrochemicals, plastics, cement, pharmaceuticals, and feed processing. Its operational principle involves a micro-motor driving a rotating paddle. When no material contacts the paddle, the motor runs continuously; upon material contact, the motor stops and triggers a switching signal. Featuring stainless steel paddles adjustable for material densities above 0.5g/cm³, it operates within -10℃ to 80℃ (extendable to 260℃ with special configuration). The device incorporates explosion-proof construction, dual-layer dust protection, and clutch mechanisms for motor safeguarding. With IP65-rated junction boxes and separable mechanical-electrical structure for easy maintenance, it supports horizontal or tilted installation in silos, hoppers, and other bulk storage scenarios for reliable high/low level monitoring. The torque spring allows sensitivity adjustment according to material characteristics while automatic slip-clutch prevents motor damage during overloads.3715
產(chǎn)品技術(shù)特點
該設(shè)備采用抗粘附電路設(shè)計減少誤信號，探頭與控制器可分離式結(jié)構(gòu)簡化安裝維護。獨特油封技術(shù)防止粉塵滲透，三層軸承支撐確保運行穩(wěn)定性。提供多種電源選項（220VAC/110VAC/24VDC），觸點容量達250VAC/10A SPDT，葉片轉(zhuǎn)速1RPM。浪涌保護技術(shù)延長探頭壽命，貼片工藝增強電路抗干擾性。適用于飛灰、顆粒、粉體及導(dǎo)電/非導(dǎo)電物料，在物料流動性變化或高粉塵工況下仍保持可靠檢測。1612
Application Scenarios
Widely implemented in material handling systems including coal bunkers (power plants), raw meal silos (cement industry), grain storage bins (food processing), and polymer powder vessels (chemical plants). Its compact design suits small hoppers while extended shaft versions accommodate deep vessel applications. The corrosion-resistant SUS304 paddle withstands abrasive materials, making it effective for fly ash monitoring in thermal power stations and powder level control in pharmaceutical mixers. Optional high-temperature models serve rotary kiln feed systems and hot material processing lines.2914

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、輕便易裝、輸出觸點容量大等特點。針對不同比重的物料可通過調(diào)彈簧的拉力來實現(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
電機帶動葉片旋轉(zhuǎn)，當被側(cè)介質(zhì)到達葉片位置時，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)的比重進行調(diào)整，物料比重大時彈簧調(diào)整到*強，反之調(diào)至*弱。
