Product Introduction of SJ-10-B Level Switch (English)
The SJ-10-B rotary paddle level switch is designed for point-level detection of bulk solids including powders, granules and lump materials in industrial applications. Operating on mechanical principle, its slowly rotating paddle (1 RPM) gets obstructed by material presence, triggering SPDT switch signal output. The device features stainless steel wetted parts, five-step sensitivity adjustment via torque spring, and IP65-rated junction box for dust protection. Suitable for installation in silos, hoppers or conveyors, it supports both flange and threaded mounting with 15-20° downward tilt recommendation for horizontal installation to minimize material impact. The built-in clutch mechanism provides motor overload protection, while maintenance-free design ensures long-term reliability in harsh environments like cement plants and feed mills. Typical applications include overfill/empty alarm and process automation control.11418
技術(shù)特點詳述
產(chǎn)品采用機電分離式結(jié)構(gòu)設(shè)計，維護時無需整體拆卸。葉片材質(zhì)可根據(jù)物料特性選配304或316L不銹鋼，軸封采用特殊油封技術(shù)有效防止粉塵滲入。工作電壓兼容AC220V和DC24V，輸出為單刀雙擲繼電器觸點（5A/250VAC）。針對不同物料密度（≥0.4g/cm³），用戶可通過調(diào)節(jié)彈簧掛鉤位置改變檢測靈敏度，共有五檔扭矩可調(diào)范圍。安裝時需注意避開進料口直接沖擊區(qū)域，建議在粉塵濃度高的環(huán)境中加裝防雨罩。71113
Key Technical Features
With modular construction separating electrical and mechanical components, the switch allows easy maintenance without full disassembly. The rotating paddle assembly utilizes wear-resistant stainless steel with shaft seals preventing material ingress. Dual microswitch configuration provides fail-safe operation: one for signal output and another for motor circuit cutoff. Standard models operate at -10~55℃ ambient temperature with 85% RH max, while high-temperature versions are available upon request. The 3W low-power motor incorporates automatic restart function when material level drops below detection point. Cable gland and threaded conduit entries facilitate field wiring.141821
應(yīng)用領(lǐng)域說明
本產(chǎn)品廣泛應(yīng)用于固體物料存儲與處理系統(tǒng)，特別適用于水泥廠生料倉、火電廠煤粉倉、化工廠塑料顆粒儲罐等存在粉塵、振動工況的場合。在飼料加工行業(yè)可用于配料秤的料位監(jiān)控，糧食倉儲中實現(xiàn)筒倉滿倉報警。其抗震防松結(jié)構(gòu)設(shè)計能有效應(yīng)對物料流動產(chǎn)生的機械振動，防粘附特性確保在潮濕粉末環(huán)境中穩(wěn)定工作。通過聯(lián)鎖控制系統(tǒng)，可實現(xiàn)自動上料、排料等流程管理。1717
Application Scenarios
Ideal for bulk material handling systems including: cement silo level control, coal bunker monitoring in power plants, plastic pellet detection in polymerization reactors, and inventory management in grain elevators. The switch s robust construction performs reliably in high-vibration environments like vibrating screens and pneumatic conveying systems. Food-grade versions with polished surfaces meet hygiene requirements in feed mills and flour processing plants. When integrated with PLC systems, it enables fully automated process sequences such as conveyor start/stop and blender charge/discharge cycles.192130

產(chǎn)品描述
阻旋料位開關(guān)也有的稱之為阻旋物位計或者阻旋料位開關(guān)、阻旋物位開關(guān)等，主要是根據(jù)它具體的不同用途的不同名稱。阻旋式料位開關(guān)是采用交流微電機經(jīng)減速后，帶動檢測葉片慢速旋轉(zhuǎn)。當(dāng)被測物料的料位上升使葉片的轉(zhuǎn)動受到阻擋時，檢測機構(gòu)主軸產(chǎn)生旋轉(zhuǎn)位移。此位移先使一個微動開關(guān)動作，發(fā)出有料的信號。隨后另一個微動開關(guān)動作，切斷微電機的電源使其停止轉(zhuǎn)動。只要倉內(nèi)的料位不變，此種狀態(tài)便將一直保持下去。
