PRINCIPLE OF OPERATION







Weldable strain gauges on
front and back of leg
More accurate, less costly
than bolt-on sensors
(Kistler Morse etc.)
Can use 2 or 4 legs
OK for 6 or more legs
H-beam, O-beam, L-beam
or square section legs
Must have at least 1500
psi stress in leg
Minimize temperature
changes for best accuracy
HOW IT’S DONE










Choose the location on leg
Grind surface until smooth
Drill cover mounting holes
Weld gauges to leg
Test gauges and connect
All gauges daisy-chained
from leg to leg and to bar
graph indicator
Seal gauges and fit cover
Seal cover
Test and calibrate
All materials supplied in kit
DEALER INSTALLATIONS




Requires special
installation tool (welder)
which can be rented
Better to purchase
welder if intending to do
many installations
Keep spare bar graph
indicators and train
personnel
Charge for installation –
one man day per silo,
gives extra income
INDICATOR FEATURES







Bar graph and digital display reads in
tons and tenths
Optional 4 setpoint relays for alarm
indication
Optional isolated 4-20mA or 0-10 volt
analog output
Up to 5 indicators in same SiloWeigh
cabinet
Simple programming/calibration
Plug-in boards make replacement easy
Does not need empty silo for calibration
ALTERNATIVE INDICATORS



Analog transmitter in
place of bar-graph will
interface with batching
controllers, PLCs
Digital transmitters
also available
Do not use weight
indicators reading in lb
or kg. This is too fine –
normal drift appears
much worse with small
graduations
IMPROVEMENTS





Calibration “block” on input changes less
than 1.3 mV removed in 2003, allowing
1-truck calibration on all silo sizes
Interface to BatchTron/RediLink
Updated manual available online
New model SiloWeigh.Net displays silos
on PC computers in local network
Internet database stores silo data for
whole company, allowing automatic
reordering and truck fleet management
OTHER APPLICATIONS







Grain – corn,

wheat, rice etc.

Animal feed mills
Breweries
Bakeries and food

Plastics, chemicals

Liquid tanks
Mines, refining
Asphalt storage
Instead of vertical
legs, use cross beams
in interconnected
frames (consult us)
Do not use for trade
Do not use for
batching, bag filling
or truck loading – not
enough accuracy
OPPORTUNITIES
Across the world, SiloWeigh
has a unique niche in the
market. It has the highest
accuracy at a modest cost;
lower than load cells. This
plant in Korea is a typical
example. All concrete plants in
Korea use some type of silo
indicator. Our dealer, Taeshin,
makes concrete plants. These
new silos are 500, 200 and 300
metric tons, fitted with
SiloWeigh.
