中文介绍： 料流检测器RT21是一种高效的物料检测设备，广泛应用于化工、塑料、水泥、制药、饲料、食品等行业。它采用阻旋式工作原理，通过检测物料对叶片的阻力来判断物料的流动状态。当物料上升至叶片位置时，叶片转动受阻，检测装置输出开关信号并切断电机电源；当物料下降时，叶片恢复旋转。该设备具有良好的密封性，能够有效防止粉尘渗入，同时具备过载保护功能，确保设备在复杂工况下稳定运行。其接触物料部分采用不锈钢材料，耐用性强，使用寿命长。

RT21料流检测器还具备多种优点，如进口马达性能可靠，扭力稳定且可调，叶片承受过重负荷时，马达回转机构会自动打滑，保护设备不受损坏。此外，该设备安装简便，可根据不同比重的物料调整弹簧拉力，以适应不同的使用场景。其工作温度范围为-10℃至80℃，适用于多种环境条件。

English Introduction: The RT21 material flow detector is an efficient material detection device, widely used in industries such as chemical, plastic, cement, pharmaceutical, feed, and food. It operates on the rotary paddle principle, detecting the resistance of the material on the paddle to determine the flow state of the material. When the material rises to the position of the paddle, the paddle rotation is obstructed, and the detection device outputs a switch signal and cuts off the motor power. When the material level drops, the paddle resumes rotation. This device features excellent sealing to prevent dust ingress and has overload protection to ensure stable operation in complex working conditions. The material contact parts are made of stainless steel, ensuring strong durability and long service life.

The RT21 material flow detector also offers several advantages. The imported motor provides reliable performance, and the torque is stable and adjustable. When the paddle is subjected to excessive load, the motor s rotary mechanism will automatically slip to protect the device from damage. In addition, this device is easy to install and can adjust the spring tension according to the specific gravity of different materials to adapt to various application scenarios. Its operating temperature range is from -10℃ to 80℃, making it suitable for a variety of environmental conditions.
