12 Media compatibility—pressure sensors only

13 Pressure sensor accuracy (drift over temperature and life)

The absolute pressure accuracy is specified in Figure 23 and Figure 24.

Figure 23 shows the absolute pressure drift over the entire specified temperature range. The absolute pressure

drift over temperature is guaranteed by production testing.

Figure 24 shows a multiplying factor that accounts for the life time drift of the pressure sensor. The results in

Figure 24 have been obtained by qualification testing to conform to the AEC-Q100[2] (Rev-H) standards.

As an example, at room temperature, the worst case drift that the pressure sensor might have after accounting

for lifetime performance is (1 kPa × multiplying factor) = 2 kPa.
