Rotary paddle level switch SOLIBA PRP

for bulk materialsfor powdersfor silo

Presentation
The SOLIBA PRP is a rotary paddle level detector designed for level detection in silos, hoppers and bins containing bulk solids. Suitable for a wide range of products such as powders, granules and free-flowing materials, it provides reliable detection of high, low or intermediate levels inside silos, hoppers or containers.

Principle of operation
Operation is based on the continuous rotation of a paddle driven by a motor. Under normal conditions (absence of product) the paddle rotates freely. When product reaches the paddle, resistance exerted by the material stops the rotation. This stoppage is detected by an internal mechanism that activates an electrical contact and generates a stop or control signal to the automation. When the level falls and the paddle is freed, rotation resumes and the system automatically resets.

Applications and advantages

• Level detection in silos, hoppers and containers for bulk products (powders, granules, cereals, pellets, etc.).
• Simple, repeatable operation even in dusty or humid environments.
• Option to fit different paddle types or process adapters according to product density and nature.
• Inclined paddle geometry suitable for side mounting, promoting product flow and reducing buildup.
• Compact design for confined spaces and hard-to-reach areas.
• Construction options with plastic housing and stainless steel paddle for demanding industrial sectors (food, chemical, cement, plastics, etc.).
