    Hi all,
    I am working on a project in which i need to design a scale in which there will be 4 three wire load cells (http://www.gavincc.com/product/60336222130-801015496/GMl623_halfbridge_micro_3kg_load_cell.html ).
    I have connected the these 4 load cells as shown in the image given below:
    The E+ in my circuit is 2.036V constant reference and E- =>GND.
    What should be the max output voltage of the scale at 12kg? at No load my scales output is 1.2mV. As far as i know if rated output of the load cell is 1mV/V and if you give 5 V excitation then at max load the output will be 1mV X 5V=>5mV at Max load.
