English Introduction
Product Overview
The SR2-20F-AB-270 rotary paddle level switch is designed for detecting solid materials (powder, granules, lumps, or viscous substances) in silos, hoppers, or conveyor systems. Featuring a stainless-steel rotating paddle and robust construction, it ensures reliable operation in industries like chemicals, power generation, cement, and food processing. The sealed housing prevents dust ingress, enhancing durability in harsh environments. 1822
Operating Principle
A micro-motor drives the paddle at 1 RPM. When material obstructs rotation, the mechanism triggers a switch signal and cuts power; when material level drops, the spring-restored paddle resumes rotation, resetting the signal. Adjustable torque settings accommodate materials with varying densities (≥0.4g/cm³). The overload clutch protects the motor from damage. 413
Key Features
The aluminum alloy housing offers high impact resistance. With adjustable torque and IP65 rating, it supports horizontal (10°~20° tilt recommended) or vertical installation. Operating temperatures range from -10°C to 80°C (extendable to 400°C). Available in 220VAC/110VAC/24VDC versions, the SPDT contacts handle 10A/250VAC loads. Maintenance is simplified via modular design. 1125
Applications
Ideal for coal bunkers, slag bins, and raw material storage in cement/steel plants. Compatible with PLC/DCS for automated level control. Installation should avoid direct material flow; protective baffles are suggested if unavoidable. Multiple process connections (flange/thread) ensure flexible deployment. 310
