1. Function and features
The sensor detects the
level
of media in tanks.
• The unit detects by direct contact with the medium whether the
requested level is reached and indicates this by a switched signal
(N.O. or N.C., programmmable by wiring;
→
page 13).
• The level is determined by the installation length (
→
page 14,
Installation).
• The unit can be adjusted to the respective application (
→
page
15, Programming).
Applications:
• Electrically conductive or non conductive media are detected.
•
Installation: vertical
from the top.
The unit operates with
radial detection characteristics
. Therefore
media below the active zone are not detected in the case of verti-
cal installation. Despite different electrical properties media are only
detected when the
active zone is covered
.
• The unit is
virtually immune to build
-up of almost all media on
the probe. The position of the switching level within the active zone
can however change with build-up.
• For water and hydrous media with temperatures > 35°C install the
unit into the climatic tube (order no. E43100, E43101, E43102,
E43103).
Possibly critical media
:
• Electrically non conductive media which leave a permanent electri-
cally conductive build-up on the probe (e.g. oil polluted with metal
dust).
• Dry granulated materials with low density.
• The unit cannot be used for acids and alkalis.
