Paddle level switch working principle

Paddle level switch | Rotary paddle switch

Paddle level switch working principle is given below. In paddle Type level Switch rotating vane continuously rotate by a motor. When this pallet comes into contact with the material, more force than the rotating torque will be applied to the pallet and rotation will stop. The level switch detects rotation, stops and sends the contact.

The paddle type level switch is used for the detection of dust level or litter material in silo, hoppar, etc.

Working principle of paddle level switch

A detection paddle inside the tank is turned by motor, the paddle is arrested to rotate by a load of the object to be measured. An actuator fixed on the motor activates a limit switch to stop the motor, providing a detection signal.

paddle type level switch working

Principle: A metal paddle is slowly rotated by an electric motor in a paddle level switch. The material in the container will load the paddle once it reaches the paddle’s level. When the paddle is under enough torsional stress, a torque switch that is connected to the switch’s motor turns on.

Paddle level switches are made with the intention of performing point level sensing in dry bulk materials. A one rpm magnet driven motor turns the switch’s paddle. The movement of the paddle is obstructed when the product accumulates in a container, setting off an alert.

Application of Rotary paddle level switch

In bulk solids, point level detection
In silos containing bulk solids, the generally applicable paddle point level switch is used as a full, empty, and requirement alarm.

Advantages of Rotary Paddle level switch

Monitoring of rotation automatically (optional).
Failures can be identified without taking the instrument apart.
Simple installation
Housing made of durable plastic with a transparent cover.
Device to secure the cover.
Setting density without using any tools.
