PRL-200料位開關
PRL-200阻旋式料位開關產品介紹（中英文）
PRL-200阻旋式料位開關是一種依據被測物料密度設計的接觸型料位檢測裝置，適用于粉粒狀、塊狀物料的料位監測。該產品采用永磁電機驅動葉片旋轉（轉速5-6轉/分），當物料上升阻礙葉片轉動時，機械傳動機構會觸發開關信號并自動切斷電源。其耐熱性能支持罐內最高200℃的工作環境（PRL-200S型號可達400℃），軸保護管設計增強密封性，料桿標準長度150mm并支持定制加長。產品通過鋁合金鑄造殼體與靜電噴塑工藝實現耐沖擊和防腐蝕，葉片過載時會自動打滑保護電機，維護時無需整體拆卸料倉。典型應用包括電力、水泥行業的原煤倉、生料倉等場景，安裝時需避開進料口并調整彈簧扭力以適應不同物料密度。135
The PRL-200 Rotary Paddle Level Switch is a mechanical point level detector designed for bulk solids like powders and granules. Its rotating paddle (1 RPM) gets obstructed by rising material, triggering a microswitch signal through spring-loaded displacement mechanism. The heat-resistant version withstands up to 200°C process temperature (400°C for PRL-200S) with optional air cooling accessories. Standard 150mm probe length can be customized in 100mm increments, while the triple-sealed shaft prevents dust ingress. The aluminum alloy housing with anti-corrosion coating ensures durability in harsh environments like coal plants and cement silos. Featuring overload slip clutch protection and top/side mounting options, it requires no sensitivity adjustment and maintains stable performance even with material property variations. Installation recommendations include avoiding direct material flow impact and selecting appropriate blade size for lightweight substances.51214
產品特點與工作原理
該設備通過純機械結構實現料位檢測，無需電子調試即可投入運行。微電機經減速后帶動檢測葉片低速旋轉，物料阻擋葉片時會使主軸產生旋轉位移，先觸發料位信號微動開關，隨后切斷電機電源；當料位下降后，彈簧機構自動復位并恢復電機運轉。獨特的三重軸密封和整塊鋁合金散熱片設計有效應對粉塵侵入和高溫工況，且扭力可通過彈簧調節以適應0.5g/cm³及以上密度的物料。垂直安裝時可選450-3000mm加長軸型號（PRL-200EB/ED系列），水平安裝需保持接線盒朝下防雨。相比其他原理的料位開關，其抗振動、抗沖擊性能較強，并能克服物料粘附問題。6922
Key features include maintenance-free operation with all-metal construction and IP65 protection. The motor-driven paddle rotates until material obstruction activates the torque-sensitive mechanism, which simultaneously engages SPDT contacts (10A/250V capacity) and stops the motor. Automatic restart occurs when material level drops below the paddle. Customizable options include flange types (JIS5K65A standard), probe lengths, and paddle configurations (80×80mm standard blade). The device s mechanical design eliminates false signals caused by temperature/humidity changes, with optional extended shafts for deep silos. Noteworthy applications involve fly ash detection in thermal power plants and raw material monitoring in steel mills, where its wear-resistant SUS304 blade ensures long service life.101720
應用場景與安裝建議
廣泛應用于冶金、化工等行業的料位控制場景，特別適合存在振動或高溫的工況環境。在水泥廠中可用于熟料倉的滿倉報警，安裝時需在葉片上方加裝防護板避免物料直接沖擊；檢測輕質物料時可更換大尺寸葉片提高靈敏度。罐外使用環境溫度建議不超過55℃，高粘性物料推薦頂置垂直安裝方式以減少掛料影響。對于400℃以上超高溫場合，可配合風冷裝置使用。產品提供AC100-220V或DC24V多種電源規格，功耗約2.5-4W，法蘭接口支持JIS標準及其他定制規格。71519
Typical installations cover material level monitoring in hoppers, bins and silos across mining, food processing industries. For cohesive materials like asphalt, top-mounted vertical installation with extended shaft is recommended to prevent material buildup. The paddle should be positioned away from filling streams, with protective baffles added when handling abrasive substances. In outdoor applications, rain shields are advised for vertical installations. Multiple units installed in same vessel require minimum 1m spacing to avoid shaft entanglement. The product s straightforward mechanical operation makes it suitable for remote locations where complex electronics may fail, while its modular design allows field replacement of components like torque springs or bearings without full disassembly.212425

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。
