RD-11料位開關
RD-11阻旋式料位開關產品介紹(中文)
RD-11阻旋式料位開關是一種用于固態物料(如粉狀、粒狀、塊狀)的物位監測設備。其核心原理是通過微型馬達驅動葉片旋轉,當物料接觸葉片時,馬達停止運轉并輸出開關信號,實現料位報警或控制。該設備采用雙層防塵密封設計和特殊油封技術,能有效防止粉塵滲入,適用于水泥、煤炭、化工等高粉塵環境。葉片扭力可根據物料比重靈活調節,并具備過載保護功能,當葉片承受過大阻力時,離合器自動打滑以保護電機。產品支持水平或垂直安裝,法蘭連接規格可定制,適應不同工況需求。
RD-11的葉片材質為不銹鋼,耐腐蝕且耐磨,適用于-20℃至80℃的環境溫度(高溫型號可擴展至200℃)。其結構簡單,維護便捷,廣泛應用于冶金、飼料、食品加工等行業,特別適合料倉、灰庫等場景的料位監測。設備功耗低(3W),支持AC220V或DC24V供電,輸出接點容量為5A/250VAC,防護等級達IP65,確保在惡劣條件下穩定運行。
RD-11 Rotary Paddle Level Switch (English Introduction)
The RD-11 rotary paddle level switch is designed for monitoring solid materials such as powders, granules, and bulk solids. It operates by rotating a paddle via a micro motor; when material obstructs the paddle, the motor stops and triggers a switch signal for level control. Featuring a dual-layer dust-proof seal and specialized oil sealing, it effectively resists dust ingress, making it suitable for high-dust environments like cement silos, coal bunkers, and chemical plants.
The paddle torque is adjustable to accommodate materials of varying densities, and an overload protection mechanism disengages the clutch to safeguard the motor if excessive resistance occurs. The switch supports both horizontal and vertical installation, with customizable flange connections for flexible application. Constructed with stainless steel paddles, it offers corrosion resistance and durability within a temperature range of -20℃ to 80℃ (extendable to 200℃ for high-temperature models).
With low power consumption (3W) and compatibility with AC220V/DC24V power supply, the RD-11 provides reliable performance in industries such as metallurgy, feed processing, and food production. Its SPDT output (5A/250VAC) and IP65 protection ensure stable operation under harsh conditions. The simple mechanical structure minimizes maintenance needs, ideal for continuous monitoring in hoppers, bins, and similar storage systems.

一、產品簡介:
阻旋開關是用于固態物料(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彈簧的拉力來實現,其接觸物料部分全為不銹鋼材料。阻旋開關在化工、塑料、水泥、制藥、飼料、食品等行業得到了廣泛的應用。
二、工作原理
電機帶動葉片旋轉,當被側介質到達葉片位置時,葉片手足停止轉動,從而觸動后面的微動開關輸出開關信號,當被測介質下降離開葉片時,葉片在彈簧的作用下恢復原位繼續轉動。彈簧的拉力可根據所測介質的比重進行調整,物料比重大時彈簧調整到*強,反之調至*弱。
