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 ventilation
is realised via the capillaries in the permanently connected cable. The
filter element is replaced by a blind stopper.
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 housing
and connection cable are not exceeded.
