If several load cells are wired to one input, their signals add up: you get a total weight, but not the distribution. That is exactly right for a vessel scale and useless for load distribution.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIf the measuring points are to stay separate – because you want to detect uneven loading, monitor two independent axes or watch two limits individually – every bridge needs its own channel.
