VEGA VEGABAR 65 Profibus PA - Manual (Page 12)

Ventilation for the measuring cell or measuring cell electronics 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.

Information:
Make 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 permanently 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.
