RLI Shaker - Rotary Level Indicator

RLI Shaker - Rotary Level Indicator

Product catalog summary

Application
The RLI “Shaker” rotary paddle switch is designed for detecting high or low levels of bulk granular solids in bins, tanks, and silos. It is also suitable for detecting plug conditions in spouts, offering long life and failsafe detection.

Method of Operation
The device uses a stepper motor drive to rotate clockwise and counter-clockwise, followed by a shaking action to remove excess material buildup. If the paddle's rotation is obstructed by material, the electronic circuit signals for level indication or control. The design eliminates the need for a gearbox or clutch, as the motor is directly coupled to the output shaft, making it durable and resistant to damage from forced or backward rotation. The adjustable torque control allows for easy calibration across different material densities without changing paddles.

Product Information RLI Rotary Level Indicator APPLICATION The RLI “Shaker” rotary paddle switch is used to detect high / low levels of bulk granular solids in bins, tanks and silos. It can also be used to detect plug conditions in spouts, where long life and failsafe detection is required. METHOD OF OPERATION Utilizing a unique stepper motor drive, the RLI “Shaker” rotates clockwise, then counter-clockwise and then shakes to shed any excess material build up. If the paddle rotation is impeded at any time by the bulk material then the electronic circuit provides a signal for level indication or control. The RLI “Shaker” uses fewer mechanical parts compared with standard rotary level indicators. No gearbox or clutch is required as the stepper motor drive is directly coupled to the output shaft and is practically indestructible and cannot be damaged by forced or backwards rotation. Also, an adjustable torque control allows one unit to cover many different densities of material, and provides easy on site calibration without having to change paddles.
