TIDA-00765: is it possible for TIDA-00765 over 15kg Range as like 1. 30~80Kg 2. 65~155kg 3. 140~350kg application

Hi Philip,

sorry for the delayed answer. The TIDA-00765 was designed with a food processor in mind, showing the high linearity for a range of 5kg (33% of max system weight = 15kg) with 1g (5000 steps ~ 5kg) resolution. For your example (1) we would be looking at a system weight of 80Kg with a range of 50kg (38%). I would expect this to result into a 6g resolution as you would pretty much only scale the strain gauges up and extend the ADC's resolution across a wider range. But apart from that a quite similar scenario.

For the other two examples you are extending the range to ~60% of the max system weight. I don't think one could simply scale the results from TIDA-00765 for those two as you are asking for an even wider range of linearity. You would need to go back into analyzing the full system again with the formulas provided in the Design Guide.

I hope this helps.

Best regards,

Michael
