Innovative Bin Level Indicator
Locate Almost Anywhere
There are few limits on the mounting location. The shear resistant feature means that it may be
located high or low on the bin wall. Other technologies require a shield to prevent damage by the
weight of the material moving down in the bin. A shield is difficult to install and may interfere with the
operation. The Model SPM may be mounted almost anywhere except the top of the bin and requires
no shield.

Resistant to Damage from Shear Forces
Many sensor technologies are easily damaged by the movement of material as it moves down in the
bin. The weight of the material may bend a vibration, RF, or capacitance probe. The moving
material may damage the shaft or paddle on a rotary unit. The Hensortech Swinging Paddle
Indicator has a flexible section that allows the paddle to retract against the bin wall if forced down by
the weight of the material. When material moves away from the paddle, it springs back, undamaged
to its normal position.

Locate in the Material Stream
Unlike other sensor technologies, the Hensortech Swinging Paddle Indicator may be mounted in the
material stream in most cases. It may even be mounted in the cone of a cyclone with no protective
shield. The paddle is somewhat inline with the material movement. The moving material tends to
slide off of the paddle and therefore not give a false indication. This is a great advantage when
mounting in a chute. The flexible section of the paddle prevents any large chunks which hit the
paddle from causing damage to the paddle or shaft.

Not Effected by Stringy Material
Stringy material may wrap up on the paddle of a rotary unit and may hang on the probe of an RF or
vibration unit, giving a false signal. Such material will slide off of the paddle of the Hensortech
Swinging Paddle Indicator.

Rugged Construction
The wetted parts are all stainless steel. There are no ball bearings or lip seal. The stainless shaft
rotates in a stainless bearing surface. This construction is very resistant to damage due to
contamination or moisture and is easily cleaned. There is a purge opening between the outer
bearing and the enclosure, preventing any bulk material from leaking into the motor enclosure. A
very small amount of leakage will occur at the outer bearing. For most materials such as sawdust or
grain, this leakage is not significant. However, the Model SPM should not be used where zero
leakage is required.

Local Indication of Operating Status
A sunlight visible light indicates the presence of material at the paddle. The motion of the paddle
shaft can be easily viewed to confirm that the unit is operating properly. Relay output Fail Safe high
or low selection is standard.

Reliable Sensitivity
The Swinging Paddle Indicator is inherently sensitive. The standard 10 inch long paddle has a swing
radius of 12 inches. This is the equivalent of a 24 inch diameter paddle on a rotary unit. This large
radius is practical because the paddle only travels through a 60 degree arc. For very low density
materials, an even longer aluminum paddle may be used for increased sensitivity. In addition to the
flexibility of the different types of paddles, there is a very effective and easily changed sensitivity
adjustment inside the unit.

Easy Mounting
The exclusive system means speedy installation and even faster mounting. No large
holes or welded half-couplings are required. Simply lay out the holes with the included template.
Drill one 1 1/2” hole with a hole saw and 4 small holes for the mounting bolts. No welding or flame
cutting is required. A hole saw, drill bit, and cordless drill are all that is needed to mount the unit.
After attaching the mounting plate to the bin wall, insert the unit into the 3” x 3” mounting plate and
tighten one clamp screw. This simple and reliable attachment is very convenient. By loosening only
one screw, the Model SPM can be quickly removed and replaced for cleaning or inspection. There is
no spinning of the unit which often damages the electrical wiring. If the optional Brad Harrison quick
connect is used, the unit can be replaced in seconds.
