In the following schematic using the resistance values shown, the equation for the summed signal is:
V
sum
= 2/5 (V
left
+ V
right
)
The resultant voltage for 10 volts applied to V
left
and V
right
would therefore be 8V.The maximum load
experienced by each loadcell’s output stage would be 7.5K ohm, necessitating that each loadcell amplifier
be capable of 1.3 mA of load current.
