BA_EN_FT90 95/108
7.4.2 Temperature
The limit values apply for plastic and all sensors mounted at an offset.
To ensure that the specified measurement error is upheld for stainless steel
sensors mounted directly on the device, an air flow of at least 0.1 m/s must be
guaranteed.

7.4.3 Differential pressure
• The specifications for the measurement error include linearity and hyster-
esis.
• All specifications relate to the basic measuring range (see the type plate)
and a compensation range of -20 to +70°C.
