entilation 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.

ake sure that the filter elements are always free of buildup during
operation. A pressure washer must not be used for cleaning.
W ith 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.
H igher 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.
