1. Product introduction of anti-rotation level switch.
ZX series rotary resistance level switch is a level controller for solid materials (including powder, block, granular, gel, etc.). It has the characteristics of good sealing, strong overload capacity, light weight and easy installation, and large output contact capacity. For materials with different specific gravity, the tension of the spring can be adjusted, and the part in contact with the material is all stainless steel. Rotary level controllers are widely used in chemical, plastic, cement, pharmaceutical, feed, food and other industries.
Second, the working principle of the anti-rotation level switch.
ZX series rotary level controller adopts the principle of electromechanical level control, and the level switch is in contact to measure the material level. When there is no material in the blade part of the silo, the leveler is energized, the indicator light is on, and the blade rotates counterclockwise; When there is material in the blade part of the silo, the blade rotation is blocked, the control signal is converted, and then the power supply of the motor of the material level device is disconnected, and this state is maintained until there is no material in the blade part, the material level switch and the level device automatically resets, the motor power is turned on, the indicator light is on, the blade begins to rotate, and the control signal is switched.

Fourth, the selection of anti-rotation level switch products
5. Precautions for the installation of the anti-rotation level switch.
When the medium temperature exceeds 80, please choose the high temperature series products.
The contiguous part is 1"For threading, sickle-shaped blades can be used to lock directly into the teeth.
The junction box outlet must face downwards and the cable retention nut must be locked.
When installed on the side, the controller can be installed at an angle of 15 -20 horizontally to reduce the impact on the material.
If necessary, a steel plate can be welded on the wall of the warehouse above the product to reduce the impact of the material product.
