NOTES
1) Deviation at one half full-scale pressure from the least squares best line fit over pressure range.
2) Maximum difference of output voltage after 1 pressure cycle at any pressure within the operating pressure
range.
3) Maximum difference in offset after one thermal cycle from -40°C to +125°C.
4) Same as 2) after 10 pressure cycles.
5) Slope of the end-point straight line from 25°C to 60°C.
6) Not 100% tested.
7) MS5412-BM: Max. 0.3% FS
8) This sensor family is optimised for the linearity; it is suitable for applications with higher pressure where the
linearity requirement is less critical.
