I used MICRIO MPU for my Load Cell - Modbus interface test.
I did ADC and Load Cell noise test.
Left to right: MICRIO MPU, DI8 input module, Load Cell - Modbus interface, 0.2 ton Load Cell.
Around 120 ADC counts of noise. Full ADC resolution is 24bit = 2^24 = 16,777,216.
It's around 17 noise-free bits.
0.2 ton load cell has range 400 kg (200kg for compression and 200kg for tension).
For 400 kg range, with 17bit resolution, I can achieve an accuracy around 3 grams.
Not so bad)
