4-3-2. Load Cell Installation
1) You can connect Max. 8pcs of same capacity Load cells at once. (350Ω)
2) You have to make horizontal balance on the ground.
3) If you install more than 2pcs of Load cells, use Summing box and adjust output signal difference
as minimum. It can make wrong weighing process caused by each load cell’s variation.
4) If there is some temperature difference around Load cell, it can cause wrong weight measurement.
5) Don’t do Welding job or Arc discharge around installation place. But, there is no choice, please
disconnect power cable and Load cell cable.
6) If you measure static electricity material, please make earth between down part and up part of
Load cell.

4-3-3. Formula to plan the precise weighing system
This “SI 4400” weighing controller’s Max. input sensitivity is 0.2㎶/ Digit.
And for precise weighing system, the following formula must be satisfied.
Caution : “Input sensitivity” means Min. output voltage variation of weighing part to change 1digit. So,
please do not make large input voltage to make reliable weighing system.
Single Load cell use
EⅹBⅹD
A : Load cell capacity(kg)
B : Load cell Voltage(mV)
D : Digit
E : affirmation Voltage of Load cell
N : Number of Load cell
0.2㎶≤

AⅹN
Example1.)
Number of Load cell : 1pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 0.05kg
Affirmation Voltage of Load cell : 5,000mV
Max. Capacity of Weighing System : 300kg
Then, estimation result for this weighing system with formula,
5000ⅹ2ⅹ0.05
= 1 ≥ 0.2㎶
The calculated value is larger than 0.2㎶, so this
system has no problem.
500
Example2.)
Number of Load cell : 4pcs
Load cell capacity : 500kg
Load cell Voltage : 2mV/V
Digit : 0.10kg
Affirmation Voltage of Load cell : 5,000mV
Max. Capacity of Weighing System : 1,000kg
Then, estimation result for this weighing system with formula,
5000ⅹ2ⅹ0.10
= 0.5 ≥ 0.2㎶
The calculated value is larger than 0.2㎶, so
this system has no problem.
