PRODUCT INTRODUCTION

Rotary resistance 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 gravities, it can be realized by adjusting the tension of the spring, and the parts in contact with the materials are all stainless steel materials. Rotary resistance switches have been widely used in the chemical, plastic, cement, pharmaceutical, feed, and food industries.


WORKING PRINCIPLE

The motor drives the blade to rotate. When the measured medium reaches the position of the blade, the blade is blocked and stops rotating, thereby triggering the micro switch behind to output a switch signal. When the measured medium drops away from the blade, the blade returns to its original position and continues to rotate under the action of the spring. . The tension of the spring can be adjusted according to the specific gravity of the measured medium. The spring is adjusted to the strongest when the material has a high specific gravity, and vice versa.


PRODUCT FEATURES

(1) American small hopper professional technology, supported by three bearings, more reliable operation;

(2)The original sealing design can prevent the infiltration of dust (patent actual);

(3)The torque is stable and reliable and the torque can be adjusted;

(4)The blade is under heavy load, and the clutch automatically slips to protect the motor from damage;

(5)Electromechanical separation structure, the whole is free of disassembly and easy maintenance;

(6)The junction box has an IP65 protection level, good airtightness, and can be used outdoors;

(7) Special blades can be used for low-density materials;

(8)It can be used in a wide range of applications such as steel, cement, electricity, feed, chemical plastics, chemical fertilizers, etc.;
