dear sir
how can i connect ina 128 ic to the weighing balance transdusar or loadcell
i have using adc adc1232 and the output of loadcell is 1mv/v what is the sutaible gain for this type of configuration
aleready i had done connection mentoined in ina128 datasheet but its not working properly the variation occurs in the circuit
and what is the sutaible current to fed to ina128
sir if possible pls send me some circuit diagrams for my project
your reagarding
Jayesh,
Figure 4 in the INA128 data sheet shows connections to a bridge sensor or load cell. I've shown some more detail below. I recommend +/-15V power supplies. Current consumption will be approximately 700uA from both power supplies.
Commonly used gains with load cells range from approximately 200 to 1000. I've shown a gain of 500 below. The required gain depends on the full scale load placed on the cell.
If you can provide more information on the behavior of your circuit I may be able to help further.
Regards, Bruce.
