dancan,秤重传感器是可以应用在高原的，以下是德国秤重专家给予的解答，所以你完全可以放心。

the 3000m mentioned in the manuals are related to the accuracy of a weighing system. The weighing force "g" is not the same at sea level and in the mountain.
Also 3000m are mentioned for Simatic module, not the load cells, because of the cooling of the module, the air is thinner and does not cool as good as on sea level.
