ZX21AB料位开关
ZX21AB阻旋式料位开关产品介绍（中文）
ZX21AB阻旋式料位开关是一种用于固态物料（如粉状、粒状、块状或胶状）的物位控制设备，广泛应用于化工、塑料、水泥、制药、饲料及食品等行业。该产品采用永磁电机驱动叶片旋转，当物料接触叶片时，阻力传递至检测装置并触发开关信号，同时切断电机电源；物料下降后，叶片恢复旋转。其设计特点包括密封性良好、过载保护能力强、安装简便，且输出触点容量较大。接触物料部分采用不锈钢材质，适应不同比重物料的需求，可通过调整弹簧拉力实现灵敏度调节。产品结构轻巧，适合水平或垂直安装，水平安装时建议叶片与水平面呈10°~20°夹角以减少冲击。防护等级为IP65，适合粉尘环境使用，叶片转速为1转/分钟，工作温度范围覆盖-10℃至80℃（特殊定制可达更高温度）。1569
ZX21AB Rotary Paddle Level Switch (English)
The ZX21AB rotary paddle level switch is designed for solid material level control, including powders, granules, lumps, and viscous substances, commonly used in industries such as chemicals, plastics, cement, pharmaceuticals, feed, and food processing. It operates via a permanent magnet motor that rotates a paddle; when material obstructs the paddle, the resistance triggers a switch signal and cuts off the motor power. Once the material level drops, the paddle resumes rotation. Key features include robust sealing, overload protection, easy installation, and high-capacity output contacts. The material-contact components are stainless steel, with adjustable spring tension to accommodate varying material densities. Suitable for horizontal or vertical mounting (10°~20° downward tilt recommended for horizontal installation to minimize impact), it offers an IP65 protection rating for dusty environments. The paddle rotates at 1 RPM, with a standard operating temperature range of -10°C to 80°C (extendable via customization).161113
产品特点与优势（中文）
ZX21AB采用独特的三轴承支撑结构和油封设计，有效防止粉尘渗入，确保长期稳定运行。其扭力调节功能可适应不同密度物料，叶片过载时离合器自动打滑以保护电机。接线盒设计兼顾密封性与户外适用性，维护时无需整体拆卸。适用于钢铁、电力等行业，尤其适合高粉尘或细颗粒物料的仓内监测。叶片材质为SUS304不锈钢，耐磨损且抗腐蚀。安装时需避开进料口，必要时加装防护挡板。56923
Features and Advantages (English)
The ZX21AB features a triple-bearing support system and specialized oil seals to prevent dust ingress, ensuring durability. Torque adjustment allows customization for material density, while an automatic clutch protects the motor from overload. The sealed junction box is suitable for outdoor use, and internal components can be serviced without full disassembly. Ideal for high-dust or fine-particle applications in industries like steel and power generation, its SUS304 stainless steel paddle resists wear and corrosion. Installation should avoid direct material flow paths, with optional protective baffles for high-impact areas.691117
ZX21AB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。
