1)
In case of condensation of water vapor on the sensor surface,
the measurement error may exceed the basic error till a moment
of drying up the sensor structure
2)
The absolute temperature measurement range is –30...85
o
C but the
measurement class is not guaranteed beyond the basic range
3)
Admissible condensation of water vapor when using additional sensor
shields, see Tab. 9)
4)
For air flow < 0.5 ms, the temperature and humidity measurement
error may increase by 100%.
