Working principle of Shandong Zhuoxin RT-20 anti rotation material level switch& nbsp;   Using a permanent magnet motor to drive the rotation of the blades, when the detected material rises to the position of the blades, the rotation of the blades is hindered. This resistance is transmitted to the detection device inside the junction box through the transmission shaft. The detection device outputs a switch signal to the outside and cuts off the power supply of the motor to stop the blades from rotating. When the material decreases, the resistance of the blades disappears, and the detection device relies on the tension of the spring to return to its original state, and the blades return to their rotating state. For materials with significant differences in specific gravity, the spring tension can be adjusted. When the specific gravity is high, the spring tension can be adjusted to * *, otherwise it can be adjusted to * * weak. Product features and technology make operation more reliable* The sealing design can prevent dust from infiltrating along the axis (design); Stable and reliable torque, with adjustable torque size; The blades bear heavy loads, and the clutch automatically slips to protect the motor from damage; It is easy to inspect and repair internal components without the need to remove them from the barrel groove as a whole; Junction box design, good sealing, reliable for outdoor installation and use; Lightweight and easy to install; Suitable for a wide range of industries, such as steel, cement, electricity, feed, chemical plastics, chemical fertilizers, etc. Technical parameters of Shandong Zhuoxin RT-20 rotary level switch:

Torque adjustment
According to the density of the tested material, the tension of the torque spring needs to be adjusted. When the specific gravity is high, the tension of the torque spring needs to be adjusted to strong, otherwise it needs to be adjusted to weak<
※ Do not replace the torque spring randomly to avoid misoperation
Installation precautions
1. Before installation, please confirm whether the power supply voltage is consistent with the voltage indicated on the label.
< br/>2 、 The anti rotation material level switch should be avoided from being installed at the feeding port. If it cannot be avoided, a protective baffle can be added to protect the blades from material impact< br/>3 、 When installing horizontally, the wire inlet of the junction box should face vertically downwards, and the cable fixing nut should be tightened. If possible, a rain cover can be added< br/>4 、 Confirm whether to install horizontally or vertically before installation< br/>5 、 When installing horizontally, the blade should be installed at an angle of 10-20 ° downwards to reduce material impact< br/>
