RS4000 Rotation Switch Series

Brand: Hawk Measurement Systems

The RS4000 Rotary Paddle Switch slowly rotates until the measuring vane is covered by bulk materials, causing it to stop rotating.

The reaction torque thus generated is converted into an electrical signal.

The RS4000 is typically used for safe and multi-purpose solid level monitoring in all types of containers and silos, it can be used with all bulk materials with a density from starting 100g/l (> 6 lb/ft_).

Principle of Operation The rotating measuring vane is driven by a brushless synchronous motor.

Once the material level reaches the vane, it stops rotating, which is detected by a micro switch to stop the motor and switch the level output.

Once the material level begins to fall and the vane is free of material the motor will restart and the vane will rotate again.
