Can the number of load cells be designed arbitrarily?

Is it possible to have a weight sensor under the device’s supports, with the device having three supports? Can the number of load cells be designed arbitrarily?
Sure. The signal voltage resulting from the parallel combination of multiple sensor outputs tends to be the average of the outputs of those sensors, which improves measurement accuracy ； The load-bearing capacity of multiple sensors should be as consistent as possible. The sensor must be placed at the point of force application. In fact, it is rare for a heavy object to require more than 4 sensors, as it can be stably supported by 2 to 4 load-bearing points; dispersing these load-bearing points using the principle of levers reduces measurement accuracy due to mechanical resistance.
It’s not possible; the number of supports is determined more by considerations of stability and safety. For round tanks, three supports can be used, one at each 120-degree interval, and they are relatively easy to adjust.
Just like with control system configuration, you simply connect as many as you need; the upper limit is determined by the manufacturer
