ILT Paddle Level Indicator
Rotary Paddle Level Switch for Silos, Bins & Hoppers
Precision Level Sensing | Dust‑Proof IP65 | All‑Material Stable Detection
The ILT Paddle Level Indicator is a heavy‑duty electromechanical point level switch engineered for high‑reliability limit detection of powder, granular, pellet, and bulk materials in silos, hoppers, bins, and conveying systems. It uses slow‑speed rotary paddle detection to trigger level signals, ensuring stable operation even in dusty, vibrating, or high‑moisture industrial environments.
Unique Core Advantages
✦ Slow‑Speed 1 RPM Paddle, Zero Material Damage
Operates at only 1 revolution per minute with gentle mechanical contact. No impact, no crushing, no material segregation—ideal for fragile, light, or abrasive bulk solids.
✦ IP65 Fully Sealed & Dust‑Proof Structure
Dual‑layer shaft seal and fully enclosed housing block fine powder and dust intrusion. Stable in long‑term cement, fly ash, chemical, grain, and plastic granule applications, almost maintenance‑free.
✦ Built‑in Overload Protection & Self‑Reset
Integrated slip clutch protects the gear and motor from sudden impact or overload. Automatic reset when material level drops, no manual intervention needed, ensuring 24/7 stable operation.
✦ Ultra‑Wide Compatibility for All Densities
Works reliably with materials from light powder to heavy granules. Sensitivity optimized for consistent triggering, no false alarms or missed signals across cement, lime, flour, plastic pellets, sand, and grain.
✦ Quick Installation & Universal Thread Mount
Standard threaded connections (G 1¼”, G 1½”, G 2½”) for top or side mounting. Retrofit friendly on existing silos and bins without modification, plug‑and‑play commissioning.
✦ Wide Temperature & Pressure Adaptability
Stable operation from -20°C to +80°C process temperature and up to 0.8 bar internal pressure. Suitable for indoor, outdoor, and harsh industrial sites.
✦ Multi‑Voltage & Reliable Signal Output
Supports AC 110V/220V, AC 24V/48V, DC 24V power inputs. Standard SPDT relay output for direct connection to PLC, alarm, or control system, strong anti‑interference performance.
