You can find further information in the operating instructions "VE-
GADIS 62" (Document-ID 36469).
The protective cover protects the sensor housing against soiling and
intense heat from solar radiation.
You will find additional information in the supplementary instructions
manual "Protective cover" (Document-ID 34296).

Condensation
In case of strong condensation, the draining of condensed water
can change the measurement accuracy. The suitable version is the
Screening against condensation. The condensation can drain off
outside on the screening tube adapter.
Typical applications of the screening tube adapters are e.g. for
condensation or sockets. Apart from the standard version, there is
a second version for vacuum with a sepcial seal. When the screen-
ing tube adapter is submerged in liquid, we recommend the use of a
vacuum-tight version.
Socket
In case of long sockets, the screening tube can increase the sensitiv-
ity of the probe by compensating the influences of the socket. The
suitable version is Capacitive screening, vacuum-tight.
When the probe is mounted laterally, buildup can accumulate in the
socket. A screening tube makes the covered part of the probe inactive
and hence insensitive to influence from buildup and socket. Hence,
the screening tube adapter excludes changing influences caused by
the medium and ensures stable measurement conditions. The suit-
able version is Capacitive screening, vacuum-tight.
