LLD20 Level Switch Product Overview
The LLD20 level switch is a robust material detection device designed for industrial applications, utilizing mechanical operation principle to monitor powdery, granular or small lump materials in both open and closed containers. Its rotating paddle driven by micro motor generates immediate switching signal upon contacting materials, providing reliable point level control for silos, hoppers and conveying systems across chemical, food processing and construction industries.58
Key Features & Benefits
Featuring fully sealed construction with specialized shaft seal, the LLD20 effectively prevents dust ingress while maintaining operational integrity. Adjustable torque mechanism accommodates materials with varying densities, and automatic clutch protection safeguards motor from overload damage. The stainless steel paddle resists corrosion, supporting horizontal/vertical installation with optional flange or threaded process connections. Maintenance-friendly design separates electrical components from mechanical assembly, with dual protection circuits ensuring energy efficiency during prolonged material presence.1628
Technical Specifications
Operating at 1RPM rotation speed, the device supports AC/DC power supplies (220VAC/24VDC) with 10A contact rating. Minimum detectable density starts from 0.4g/cm³, while temperature tolerance spans -20℃ to 200℃ (350℃ for high-temperature version). IP65 enclosure withstands harsh environments, with installation flexibility via G1½ thread or flange mounting. Simplified wiring terminals enable plug-and-play operation without complex calibration, and the torsion-spring mechanism guarantees consistent performance despite material buildup or moisture variation.2027
Typical Applications
This level finder excels in cement plant raw material bins, feed mixing towers, and polymer processing units. Its anti-clogging design handles sticky substances like fertilizers effectively, while conveyor interlocking applications optimize material flow in coal-fired plants. The system remains unaffected by particle size distribution or ambient dust concentration, requiring minimal maintenance in continuous operation scenarios spanning mining, recycling and bulk material handling sectors.929
LLD20料位開關(guān)
阻旋料位開關(guān)產(chǎn)品原理：阻旋料位開關(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)帶動葉片旋轉(zhuǎn)，當(dāng)被檢測物料上升至葉片位置時，葉片轉(zhuǎn)動受阻，該阻力通過傳動軸傳遞到接線盒內(nèi)的檢測裝置，檢測裝置則向外輸出一個開關(guān)信號，并切斷電機(jī)電源使葉片停止轉(zhuǎn)動。當(dāng)物料下降時，葉片阻力消失，檢測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。
