Ventilation for the measuring cell is realised by means of a ﬁlter

element

in the socket of the electronics housing. Ventilation for the

electronics housing is realised via an additional ﬁlter element in the

area of the cable glands.

tion:

Mak

sure that the ﬁlter elements are always free of buildup during

operation. A pressure washer must 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 ﬁx connected cable. The ﬁlter

elements are replaced by blind stoppers.

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.
