within the performance limits. Consider possible restric-
tions on the ambient temperature range caused by mating
connector used.
→ For performance limits see chapter 9 "Specifications"
The probe tip must be completely surrounded by medium.
■
Position the probe tip in the area of maximum flow rate
■
(pipe centre).
The minimum immersion depth of the probe is L ≥16 mm.
