3 Intended use
The device described here is approved according to WHG (German Federal Water Act, federal
law applicable in the Federal Republic of Germany). If the device is used as an overflow
prevention or leakage sensor according to WHG, the respective “Technical Description” (only
available in German) must be observed in addition to this documentation.
The device monitors the level (point level) and the temperature of liquid media in tanks.
It is particularly suitable for monitoring the overfilling of tanks as part of an overflow prevention system
according to WHG.
It is also particularly suitable as part of a leakage detection system in accordance with WHG to monitor
the leakage of liquid media in collection rooms, collection systems, inspection chambers and hoppers.
3.1 Type designation
Level sensor type LI213x (x = probe length coded).
3.2 Application area
Water, hydrous media, oils, oil-based media, emulsions.
3.3 Restriction of the application area
•
Use the product only for media to which the wetted materials are sufficiently resistant (→ Technical
data sheet).
•
The device is not suitable for hygienic areas.
•
The device is not suitable for applications where the probe is subjected to permanent and high
mechanical stress (e.g. bulk materials, abrasive media or fast flowing media containing solid
particles).
•
Highly conductive foam can trigger a switching operation. Check the consequences by performing
a test in your application!
