Work Principle

This is a based weighting solution,It can be used for either analog strtic weighing.No need the indicator,and it has a low cost.Usually,it connects the juncton box between the computer. The signal of some analog load cells wil be magnified after analog adding by the junction box, which will be dealed with by MCU after A/D conversion,then will output to PC by RS232 module. Please refer to following picture.

   

Note:

Multi-load cells should connect junction box then connect to ATC-108A.
