Rotary Paddle Level Switch
The Rotary Paddle Level Switch is a reliable solid material level detection device that operates using a synchronous motor coupled with a clutch.
Read MoreThe Rotary Paddle Level Switch is a reliable device for high/low level detection of powders, granules, and bulk solids in silos, bins, and hoppers. Featuring a synchronous motor and clutch, it provides precise switching, durable construction, and low maintenance, widely used in food, chemical, cement, plastics, and grain industries.
Power Supply: 220VAC / 110VAC / 24VDC (B), 50Hz
Power Consumption: 4W
Contact Capacity: SPDT, 5A / 250VAC
Dielectric Strength: AC 1500V for 1 minute
Operating Temperature: -20℃ to +80℃ (standard), -20℃ to +400℃ (high-temp type)
The Rotary Paddle Level Switch is a durable and reliable device designed for detecting the high or low level of powders, granules, and bulk solids in storage bins, silos, and hoppers. It operates via a synchronous motor connected to a clutch: the motor runs freely when the paddle is not obstructed, but stops when the paddle encounters material resistance, simultaneously triggering a contact signal. With a robust design, minimal maintenance requirements, and precise switching capability, it is widely used in industries such as food processing, chemicals, cement, plastics, and grain storage.
Fully Sealed Design – Suitable for outdoor use, preventing dust and moisture ingress.
Unique Oil Seal – Protects against fine particles entering along the shaft, ensuring long-term reliability.
Stable and Adjustable Torque – Motor torque can be fine-tuned for different material types.
Lightweight & Easy Installation – Compact design simplifies mounting and setup.
Overload Protection – Paddle withstands heavy loads; motor slip mechanism protects device from damage.
Easy Maintenance – Internal components can be inspected and serviced without removing the entire assembly.
Low Torque Version (RS80 Series) – Ideal for small bins and materials with low bulk density.
Chemical & Plastics Industry – Monitoring material levels in silos and hoppers.
Pharmaceuticals – Powder handling and storage level control.
Feed & Grain Processing – Ensuring proper material flow in storage and transport bins.
Cement & Construction Materials – Reliable detection of cement and other bulk materials.
Food Industry – Handling and monitoring of flour, sugar, and other powdered ingredients.
