Electronic level sensor
LW2120
7
Open application:
Level monitoring in open applications independent of surface and
weather conditions.
3.2 Restriction of the application area
•
The device is not approved for use in potentially explosive atmospheres.
•
The unit is not suitable for all bulk materials (e.g. dry building materials) due to their very low
dielectric constant.
•
Detection of bulk materials with a higher dielectric constant (e.g. moist building materials due to
their higher moisture content) may be possible. See: Reflectivity, effect of dielectric constant
(
u
Check the function by performing an application test.
Note the influence of conical heaps and similar effects.
u
The unit may only be installed in accordance with the applicable national and international radio
regulations and statutory provisions (
Ò
package leaflet).
Incorrect measurements may be caused by the following media:
•
heavily foaming or turbulent surfaces.
•
media which are very inhomogeneous, separate from each other thus forming separation layers
(e.g. oil layer on water).
u
Check the function by performing an application test.
u
Installation in a steady area.
w
In case of permanent signal loss, the unit generates an error message and switches the outputs to
a defined state.
Hygienic adapters must be used to ensure FDA compliance.
