RC-20F Rotary Paddle Level Switch Introduction
Product Overview
The RC-20F rotary paddle level switch is a mechanical control device designed for point-level detection of solid materials (powders, granules) in silos or containers. Driven by a micro-motor, the rotating paddle stops upon contacting materials, triggering a switch signal while cutting off power automatically. It is widely applied in feed, cement, plastics, and chemical industries for material monitoring.319
Constructed with stainless steel shafts and protective housing, the switch features dust-proof sealing and operates within -20℃ to 80℃ (high-temperature version up to 350℃). The paddle rotates at 1 RPM and supports horizontal or 15-20° tilted installation to avoid material impact. Adjustable torque springs accommodate materials with densities from 0.3g/cm³.624
Operating Principle
During no-material conditions, the motor rotates the paddle continuously. When material rises to the paddle level, resistance activates the mechanical transmission: first outputting a level signal, then disconnecting the motor. The system resets automatically after material level drops, ensuring cyclic monitoring via purely mechanical action without electronic interference.1227
Key Features
• Overload protection: Automatic motor slip mechanism prevents damage under excessive paddle load
• Adjustable torque: Five sensitivity settings adapt to materials ranging from lightweight plastics to dense metal particles
• Easy maintenance: Internal components accessible without full disassembly; customizable paddle lengths available
• Environmental resilience: IP65 rating with specialized oil seals to block dust ingress
• Flexible installation: Threaded (RC-10B), flanged (RC-11B), or shaft-protected tube (RC-20 series) mounting options415
RC-20F料位開(kāi)關(guān)
阻旋料位開(kāi)關(guān)產(chǎn)品原理：阻旋料位開(kāi)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(guò)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(kāi)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。
