You will find recommended values for socket heights in the following
illustration or the tables. The values come from typical applications.
Deviating from the proposed dimensions, also longer sockets are
possible, however the local conditions must be taken into account.

In liquids, direct the sensor as perpendicular as possible to the prod-
uct surface to achieve optimum measurement results.

Instruments for a temperature range up to 200 °C have a spacer
for temperature decoupling between process fitting and electronics
housing.
Information:
The spacer may only be incorporated up to a maximum of 40 mm into
the vessel insulation. Only then is a reliable temperature decoupling
guaranteed.
