INTRODUCTION
1.0 INTRODUCTION
The BinMaster is a rotating paddle style level sensor that provides reliable point level
detection for bulk solids, including powder, pellet, and granular materials. The unit's status is con-
tinually monitored, and its fail-safe circuitry will fail to a "safe" condition in the event of a unit fail-
ure or power failure. A visual LED continually indicates the sensor’s status, giving a quick visual
monitoring of paddle rotation, covered condition or fault condition. A status relay is also provided
for monitoring the status of the sensor.
The motor rotates the drive shaft and paddle at 1 RPM (2 RPM on 24 VDC Model).
When the vessel material fills to the level of the indicator paddle, the material causes the paddle
to stop rotating indicating a covered condition. When the material falls away, the paddle starts
rotating again to indicate an uncovered condition.
2.0 INSTALLATION
2.1 Location and Mounting
TOP MOUNT
1. Locate and cut hole in top of bin to fit outside diameter
of 1-1/4” pipe coupling (1.950”).
2. Position coupling halfway into bin and weld.
3. Turn unit so conduit opening is in desired location.
4. Add 1/4” extension pipe to desired length with standard
1/4” coupling on bottom end.
5. Cut 1-1 /4” support pipe approximately 4” shorter than overall
length of 1/4” pipe shaft when used with flexible coupling.
6. Insert 1-1/4” pipe into coupling and tighten.
7. Insert paddle into 1/4” coupling and drill holes for lock pins.
SIDE MOUNT
1. Locate and cut hole in side of bin to fit outside diameter
of 1-1/4” pipe coupling.
2. Weld on half of standard 1-1/4” pipe coupling to bin wall
flush with inside of bin.
3. Insert hub into coupling and turn so the conduit openings
are pointed down.
4. Screw paddle into place and replace lock pin.
5. Shaft and paddle should be shielded in low level
mounting when subjected to material flow.
6. For side mount, a solid coupler is recommended.
