Resistance rotary switch is a level controller used for solid materials (including powder, block, granular, gel, etc.). It has the characteristics of good sealing, strong overload capacity, lightweight and easy to install, and large output contact capacity. For materials with different densities, it can be achieved by adjusting the tension of the spring, and the part in contact with the material is entirely made of stainless steel material.
① Professional technology for small hoppers in the United States, supported by three bearings for more reliable operation; ② The unique sealing design can prevent dust from infiltrating (patented in practice); ③ Stable and reliable torque with adjustable torque size; ④ The blades bear heavy loads, and the clutch automatically slips to protect the motor from damage; ⑤ Mechanical and electrical separation structure, with no disassembly and easy maintenance as a whole; ⑥ The junction box has an IP65 protection level, good sealing performance, and can be used outdoors; ⑦ Special blades can be used for low-density materials;
Application Field
Resistance rotary level switches have been widely used in industries such as chemical, plastic, cement, pharmaceutical, feed, and food. The specific application scenarios are as follows:
Petrochemical industry: used to measure the liquid or granular material level in containers, commonly used in storage tanks, reaction vessels, pharmaceutical equipment, etc;
Food and beverage industry: used to measure the level of powdered or granular materials in containers, such as grain storage, sugar tanks, flour storage tanks, etc;
Water treatment industry: used to measure the liquid level in sewage treatment equipment or water tanks, such as sewage treatment tanks, sedimentation tanks, etc;
Power industry: used to measure the level of fuel in coal bunkers, fuel tanks, or storage tanks to help control supply and reserves.

Installation Precautions
When installing horizontally, it is recommended to install the switch at a horizontal downward angle of 15 ℃ to 20 ℃ to reduce material impact.
The entrance of the junction box must face downwards, and the cable fixing nut must be locked tightly.
During power transmission, it should be confirmed that the voltage used is correct.
The load of the controlled circuit must match the capacity of the switch contacts.
Avoid bridge breakers or vibration motors near the installation of the product.
Avoid installing switches near the feeding port to reduce blade damage and misoperation during feeding;If the switch must be installed near the feeding port, please place it 200mm above the switch Install a 2mm wide protective barrier.
When installing each product, choose horizontal or vertical installation according to its model.
When disassembling and installing the adjustable shaft length switch on site, the universal joint is connected to the transmission shaf When connecting, the locking nut must be coated with oxygen deficient adhesive and then tightened with a wrench.
On site installation and maintenance must comply with the warning of "open the cover after disconnecting the power".
There are no toxic gases present at the installation site that can corrode aluminum alloys.
The maximum temperature of the tested medium should not exceed the temperature indicated on the product label.
Do not directly strike the blades and drive shaft during product installation.
