Forum Post: RE: ADS1232

Hi Erisson, The ADS1232 was designed specifically for load cells. The ADC does not convert to weight as it measures a voltage. The degree of resolution will depend on the maximum weight of the scale divided by the total noise-free resolution of the ADS1232 . The noise-free resolution is based on peak to peak noise of your system. Unshielded cables can act as antenna to pick up noise. If you see what appears to be a sine wave in your data then most likely you are picking up power line-cycle frequency from lights, etc.. This should reduce if you use 10sps instead of 80sps as the SINC filter of the ADS1232 digital filter will notch 50/60 Hz. You can verify this by using the raw data and plotting it as a time domain plot. Best regards, Bob B
