Paddle sensors

Working principle

Rotary blade monitor
A paddle driven by a small electric motor rotates continuously inside a silo or tank. As soon as the
paddled is covered with a powder or a viscous fluid the opposing torque causes the motor to rotate
in its housing, triggers a reed contact and switches the motor off. When the level of the material falls
the motor returns to its starting position and begins to rotate again.

Area of application
Powders, granular and viscous media such as plastic granules, grain, salt, wood chips,
fodder material, milk, lubricants, oil, slurry, honey and syrup.

Temperature
Maximum 120 ° C (medium) and 80 ° C (housing).

Pressure
Only atmospheric.

Materials
Paddle and shaft made of stainless steel or aluminium.

Output
Changeover contact

Fitting and Types
Over-tank, side flange or screw-in thread. Various paddle designs for a wide variety of media.

Maximum probe length 1000 mm - 6000 mm depending on type.
