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(jié)構(gòu)與工作原理
該設(shè)備由永磁電機(jī)、傳動(dòng)軸、檢測(cè)葉片及過(guò)載保護(hù)機(jī)構(gòu)組成。電機(jī)通過(guò)傳動(dòng)軸帶動(dòng)檢測(cè)葉片持續(xù)低速旋轉(zhuǎn)（1轉(zhuǎn)/分鐘），當(dāng)物料堆積觸及葉片時(shí)產(chǎn)生阻力，該機(jī)械信號(hào)通過(guò)傳動(dòng)軸傳遞至檢測(cè)單元，觸發(fā)開(kāi)關(guān)量輸出并切斷電機(jī)電源。物料位下降后，彈簧機(jī)構(gòu)使系統(tǒng)復(fù)位并恢復(fù)旋轉(zhuǎn)。針對(duì)不同工況，可選用鐮刀型、一字型或彈簧鉸鏈?zhǔn)饺~片，安裝方式支持1"管螺紋直接固定或法蘭連接，側(cè)裝時(shí)建議傾斜15-20°以減少物料沖擊。獨(dú)特的離合器設(shè)計(jì)在葉片過(guò)載時(shí)自動(dòng)打滑，有效保護(hù)電機(jī)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
