IFM Electronic Efector 160 LI2, Руководство по эксплуатации

Страница: 22 / 33

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:
• The level is determined by the installation length (
→
Installation).
• The unit can be adjusted to the respective application (
→
Program-
ming).
• Electrically conductive or non conductive media with dielectric con-
stant >1.8 are detected.
• 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.
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).
• The unit cannot be used for acids and alkalis.
