I have built a simple scale using 4 so called 50kg load cells.
They are connected in a bridge and mounted on wooden feet of a square shaped box. All as a proof of concept which worked quite ok. The readings are all OK and deviation of +/- 2kg is totally acceptable for my project. I followed this discussion which also explains how the connection should be made properly using 4 cells.
Now I want to keep the load cells on the feet but change the shape of the scale and instead of a square use a rectangle with the following sides.
In such a form a weight distribution will not be centered all the time. The object to be weighed can shift to the right or to the left.
- Will this affect the measurements in a negative way or will the HX711 controller still take care of it and show the correct results?
- Will the measurements still be correct using 4 cells? If not what would be the proper way of weighing a rectangular shaped load?
- Would it more appropriate to measure the load with 2 cells on the right and two cells on the left and then sum it up?
