Monitor's line of rotary paddle bin monitors consists of some of the most reliable, rugged and economical point level control sensors available for detection of dry bulk materials. These easy to install units are proven performers in a wide variety of bulk materials. Monitor's paddle units can be used to eliminate bin overflow, maintain a predetermined material level, indicate plugging of conveyors and pneumatic lines or provide any of a number of level control functions. Unlike many other available paddle units, Monitor's paddle level indicators incorporate a feature that automatically shuts off the motor of the unit when the paddle is in a stalled position, which both extends the life of the motor and minimizes maintenance.

MODELS

1-8301-1 (KA)
1-8401-1 (KAX)
Monitor's KA unit is the most popular of our paddle bin monitors. This model is ideal for use in standard applications with a wide variety of materials. The KAX incorporates all the features of the KA model, but is specially designed to meet explosion-proof standards. (PADDLES Sold Separately)

1-8511-1 (Safe Point)
1-8511-2 (Safe Point Explosion Proof)
The SafePoint™ bin monitor provides the ultimate in performance wherever critical continuous operation must be ensured. Detection of both material presence and its own operational status is performed on a continuous basis. The SafePoint level sensor monitors its electrical and mechanical operating condition. Separate outputs are provided for material sense and unit status (fault conditions). (PADDLES Sold Separately)

1-4144 Stainless Steel Triangular Arc Single Vane Paddle

Provides low and high level control for light to average weight materials.

1-4137 Ex-Flex Three-Ply 20" Belt Vane Paddle

Provides low and high level control for heavy materials over 2" in diameter. Top mount only.

FLEXIBLE COUPLING

1-3335 FLEXIBLE COUPLING
The flexible coupling works to absorb heavy loads, side loads and loads caused by product surges, thus protecting the internal workings and extending the life of the paddle unit. A flexible coupling should be used with heavy materials and in top mount installations where a shaft extension is used.

MOUNTING PLATES

Mounting plates allow the paddle units to be mounted from the outside of a vessel to curved or flat surfaces. All mounting plates featured below mount via six bolts.


1-0101 Half Coupling Flexible Mounting Plate
For use in side mount installations. Available in carbon steel for general purpose applications and stainless steel for use in corrosive environments.

1-0102 Full Coupling Flexible Mounting Plate

For use in top mount installations where a shaft extension and shaft guards are required. Available in carbon steel for general purpose applications and stainless steel for use in corrosive environments.

SHAFT EXTENSIONS
1-1175-1-* Galvanized 1/4" Pipe, Sch-40
1-1175-2-* Stainless Steel 1/4" Pipe, Sch-40
Many top mount installations require that the paddle extends into the vessel to a predetermined level. Monitor shaft extensions are available in a variety of lengths up to 144" to meet these demands. (*specify length)

SHAFT GUARDS
1-1174-1-* Galvanized 1 1/4" Pipe, Sch-40
1-1174-2-* Stainless Steel 1 1/4" Pipe, Sch-40
Shaft guards are recommended for use with shaft extensions to limit the movement caused by side loading that would otherwise damage the working components of the paddle unit. Shaft guards should be the same length as the extension and should always be used when the extension meets or exceeds 18" in length. (*specify length)
