Instrumentation amplifier - Problem of noise with load cell and - My trouble: while i'm in certain locations, wherein possibly there is lots of parasitics, the sign from the ina125p varies about 5 when my hand is close to the weight cell, however not touching it! It most effective occurs at some locations however no longer others. As an instance, at home, there may be no hassle; the sign may be very strong. Also, the amplitude of the noise appears to be proportional to the benefit of the amplifier.

Update 6/05 : to be greater unique about the variation, right here are a few examples: - while the load cellular lays on a table, no forces on it, the sign (after adc) is 440 (the cost are from 0 to 1024). If i technique my hand near the cell with out touching it, the sign drops to 425 and if i touch it, it drops a bit bit more to approximately four hundred. - While i've the burden mobile in my hand, and i elevate my arm up of approximately 20 inches, the signal goes up to 460, when i come returned to the table, the signal returns returned to its preliminary fee. Because of technical constraints, i need to use a 9v battery to strength the whole machine. Also, desiring to measure the force in each directions, i need the sign that comes out of the ina125p tp be referenced to 2.5v approximately. Right here is the real schematic:.

You have to have a pass capacitor across the strength enter (100uf/10v in parallel with 0.1uf ceramic will do), 10n input caps on every enter line, as andy shows, with series resistors, and i might also suggest a 10n capacitor from reference output to ground.
