RT21料位開關
RT21阻旋式料位開關產(chǎn)品介紹（中文）
RT21阻旋式料位開關是一種用于固態(tài)物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器，廣泛應用于化工、塑料、水泥、制藥、飼料、食品等行業(yè)。該產(chǎn)品采用永磁電機驅動葉片旋轉的設計原理，當被測物料接觸葉片時，旋轉受阻并觸發(fā)開關信號，物料下降后自動恢復旋轉狀態(tài)。其核心特點包括密封性良好、過載保護機制、輕量化安裝結構以及大容量輸出觸點。接觸物料的部件均采用不銹鋼材質，適應不同比重物料的需求，可通過調節(jié)彈簧拉力實現(xiàn)靈敏度調整。典型技術參數(shù)包括220VAC/110VAC/24VDC供電選項、4W功耗、10A/250VAC單刀雙擲觸點容量以及1RPM的葉片轉速，工作溫度范圍覆蓋-10℃至80℃（特殊設計可擴展至400℃）。產(chǎn)品設計注重易維護性，無需整體拆卸即可進行內部組件檢修，IP65防護等級確保戶外使用的可靠性。1419
RT21 Rotary Paddle Level Switch Product Introduction (English)
The RT21 rotary paddle level switch is designed for detecting solid materials including powders, granules, lumps, and viscous substances, widely applied in industries such as chemicals, plastics, cement, pharmaceuticals, and food processing. Its operational principle involves a permanent magnet motor rotating a paddle, which generates a switch signal upon material contact and automatically resets when material recedes. Key features include a sealed housing, overload protection mechanism, compact installation design, and high-capacity output contacts. All material-contact components are constructed with stainless steel, with adjustable spring tension to accommodate varying material densities. Technical specifications include power supply options of 220VAC/110VAC/24VDC, 4W power consumption, SPDT contacts rated for 10A/250VAC, and paddle rotation speed of 1 RPM. The device operates within -10℃ to 80℃ (extendable to 400℃ with special configuration), featuring tool-free maintenance access and IP65 enclosure for outdoor durability. The modular design allows flexible customization of connection threads, paddle shapes, and insertion lengths to suit different vessel configurations.11221
產(chǎn)品結構與工作原理
該設備由永磁電機、傳動軸、檢測葉片及過載保護機構組成。電機通過傳動軸帶動檢測葉片持續(xù)低速旋轉（1轉/分鐘），當物料堆積觸及葉片時產(chǎn)生阻力，該機械信號通過傳動軸傳遞至檢測單元，觸發(fā)開關量輸出并切斷電機電源。物料位下降后，彈簧機構使系統(tǒng)復位并恢復旋轉。針對不同工況，可選用鐮刀型、一字型或彈簧鉸鏈式葉片，安裝方式支持1"管螺紋直接固定或法蘭連接，側裝時建議傾斜15-20°以減少物料沖擊。獨特的離合器設計在葉片過載時自動打滑，有效保護電機核心部件。4524
Application Scenarios and Advantages
Ideal for harsh industrial environments, the RT21 demonstrates reliable performance in cement silos, coal bunkers, and high-dust areas. Its three-bearing support structure enhances operational stability, while specialized shaft seals prevent dust ingress. The device excels in detecting materials with bulk densities ≥0.4g/cm³, including fly ash, grains, and plastic pellets. Compared to conventional level switches, it offers simplified installation with optional vertical/horizontal mounting, reduced maintenance through accessible internal components, and adaptable sensitivity via external torque adjustment. Typical applications span power plants (coal level monitoring), steel mills (raw material bins), and agricultural facilities (feed silos), providing cost-effective point-level control without requiring complex calibration.21625
