WIKA IPT-11 - Manual (Page 11)

The ventilation of the measuring cell is realised by a filter element in
the socket of the electronics housing. The ventilation of the electronics
housing is realised via an additional filter element around the cable
glands.

Information:
Make sure that the filter elements are always free of buildup during
operation. A pressure washer must not be used for cleaning.
Higher process temperatures mean often also higher ambient
temperatures.

Make sure that the upper temperature limits for the environment of
electronics housing and connection cable specified in chapter
"T
echnical data" are not exceeded.
2) With previous instrument versions, ventilation and pressure compensation
were carried out together via a filter element.
