Caution:
Due to the filter effect, the pressure compensation is time delayed.
When opening/closing the housing cover quickly, the measured value
can change for a period of approx. 5 s by up to 15 mbar.
Information:
Make sure that the filter element is always free of buildup during
operation. A high-pressure cleaner may not be used for cleaning.
With instrument versions in protection IP 66/IP 68, 1 bar, the ventila-
tion is realised via the capillaries in the permanently connected cable.
The filter element is replaced by a blind plug.
Higher process temperatures often mean also higher ambient
temperatures. Make sure that the upper temperature limits stated in
chapter "Technical data" for the environment of the electronics hous-
ing and connection cable are not exceeded.
