NL31料位開關
NL31阻旋料位開關產品介紹(中文)
NL31阻旋料位開關是一種用于固態物料(包括粉狀、塊狀、粒狀、膠狀等)的物位控制設備。該產品采用法蘭安裝方式,適用于化工、塑料、水泥、制藥、飼料、食品等多個行業。其核心部件采用不銹鋼材料,具有良好的密封性和過載保護能力。工作原理是通過微型電機帶動檢測葉片旋轉,當物料觸及葉片時會觸發微動開關輸出信號,物料離開后葉片自動復位。產品特點包括三層軸承支撐結構、可調節的扭力彈簧系統、自動離合保護裝置以及IP65防護等級的接線盒設計,能適應不同比重物料的檢測需求。1524
NL31 Rotary Paddle Level Switch Product Introduction (English)
The NL31 rotary paddle level switch is designed for solid material level detection, including powders, granules, lumps and viscous substances. Featuring flange mounting design, it is widely used in chemical, plastic, cement, pharmaceutical, feed and food industries. The stainless steel construction ensures durability while the unique sealing mechanism prevents dust ingress. Its operational principle involves a micro-motor rotating the detection paddle - when material obstructs the paddle, the built-in micro-switch generates output signal and cuts off power automatically. Key advantages include three-bearing support structure for reliable operation, adjustable torque spring system for different material densities, overload protection clutch mechanism, and weatherproof junction box with IP65 rating. The device maintains stable performance in various industrial environments without requiring frequent maintenance.51019
產品技術特性
該設備支持220VAC/110VAC/24VAC/24VDC多種電源輸入,觸點容量為250VAC/10A單刀雙擲。標準葉片轉速為1轉/分鐘,可檢測物料最小比重為0.5g/cm³。工作溫度范圍覆蓋-10℃至80℃,特殊型號可擴展至400℃高溫環境。產品采用模塊化設計,機電分離結構便于維護,特殊形狀葉片可適應低密度物料檢測。安裝方式靈活,既可水平安裝也可垂直安裝,建議避開進料口位置以避免物料直接沖擊。5612
Application Scenarios
This level switch demonstrates exceptional adaptability in bulk material handling systems. Typical applications include silo high/low level alarm in grain storage, powder level control in mixing tanks, and solid material detection in conveyor feeding systems. The corrosion-resistant paddle and sealed bearings ensure long-term operation even in dusty or humid conditions. For optimal performance, installation should avoid material impact zones, with protective baffles recommended when installed near charging ports. The compact design and standardized flange dimensions facilitate integration with existing industrial equipment.21724
維護與注意事項
設備維護時需定期檢查葉片轉動靈活性,清理附著物料。安裝時應確保接線口朝下并鎖緊電纜螺母,垂直安裝建議加裝防雨罩。彈簧拉力需根據物料比重調整,比重較大時調至較強檔位。產品不適用于強腐蝕性或粘性過高的特殊物料,在含有振動設備的料倉中安裝時需采取防松措施。161824

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。
三、產品特點
