Product introduction
Introduction
Resistance rotary switch, using a permanent magnet motor to drive the blade to rotate, when the measured material level rises to the position of the blade, the blade rotation is blocked, the resistance is transmitted through the drive shaft to the detection device in the junction box, the detection device outputs a switching signal to the outside, and cuts off the motor power supply to stop the blade from rotating.When the material drops, the resistance of the blade disappears, and the detection device relies on the tension of the spring to return to its original state, and the blade returns to its rotating state.For materials with large differences in specific gravity, the spring tension can be adjusted.When the specific gravity is large, the spring tension is adjusted to the strongest, and vice versa, it is adjusted to the weakest.
