The four load cells allow the 50 kg sensors to read a person’s weight, up to 200 kg, anyway. The load cells themselves are in a bridge configuration which adds the weight on each cell together.

Multiaxis load cells, those that sense more than one axis at a time, currently account for only one tenth of 1% (0.1%) of the overall load cell market, with six-degree-of-freedom force-torque ...

The sensor uses a 5-V input signal and outputs a 0 to 5-V analog signal that is proportional to the load. Full-scale output range is typically 2,000 mV, 10 times that of traditional strain-gage ...
