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料位开关
阻旋料位开关产品原理：阻旋料位开关是一种用于固态物料（包括粉状、粒状、块状、胶状等）的物位控制器。其利用永磁电机带动叶片旋转，当被检测物料上升至叶片位置时，叶片转动受阻，该阻力通过传动轴传递到接线盒内的检测装置，检测装置则向外输出一个开关信号，并切断电机电源使叶片停止转动。当物料下降时，叶片阻力消失，检测装置便依靠弹簧的拉力恢复到原始状态，叶片恢复旋转状态。在化工、塑料、钢铁、电力、水泥、制药、饲料、食品等行业得到了的应用。
