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

"Technical data" are not exceeded.

With previous instrument versions, ventilation and pressure compensation

were carried out together via a ﬁlter element.
