Water, water-based media•
Oils, oil-based media (only for operation with coaxial probe)•
Medium temperature: 0…80 °C (permanent); 0…90 °C (short-term) •
Tank pressures: -1���4 bar•
Application examples:
Detection of coolant emulsion in a machine tool�•
Detection of cleaning liquid in a parts cleaning system�•
Monitoring of hydraulic oil in a hydraulic power unit (only for operation with •
coaxial probe)
Restriction of the application area
The unit is not suitable for bulk materials (e�g� plastic granulates)•
If the unit is to be used in acids or alkalis, in hygienic areas or in electroplating •
applications:firstcheckthecompatibilityoftheproductmaterials(→chapter
13, Technical data) with the media to be monitored�
Incorrect measurements or signal loss may be caused by the following media: •
Highly absorbing surfaces (e�g� foam)� -
Intensely bubbling surfaces� -
Media which are very inhomogeneous, separate from each other thus forming -
separation layers (e�g� oil layer on water)�
Check the function by an application test�
In case of signal loss, the unit displays [E�033] and switches the outputs to a
definedstate(→11.5).
The unit is not suitable for applications where the probe is subjected to per-•
manent and high mechanical stress (e�g� strongly moving viscous media or
strongly flowing media)�
In case of operation with single probe: use preferably in metal tanks� When •
installed in plastic tanks, deterioration caused by electromagnetic interference
mayoccur(noiseimmunitytoEN61000-6-2).Remedy:→6.4.2.
In case of operation with coaxial probe: not suitable for viscous media and •
media prone to formation of deposit�
