4 Functions and features

The unit continuously detects the level of liquids in tanks and generates output

signals according to the parameter settings�4 switching outputs are available:
• 3 freely programmable switching outputs (NC / NO)
• 1 switching output for overflow prevention according to WHG* (NC)

* Building authority approval according to the German Federal Water Act (WHG)�

If the unit is used as overflow prevention with building authority approval

according to the German Federal Water Act (WHG), please observe the

corresponding chapter (= Technical description) of the documentation!

4.1 Operation with coaxial probe

Only operate the device with coaxial probe! Operation with single probe is

not supported by this unit version�

The coaxial probe is made up of an inner probe and an outer probe pipe (coaxial

pipe)� The probe is centred in the coaxial pipe by one or several spacers�

When using a coaxial probe, media with a low dielectric constant

(e�g� oil and oil-based media) are detected in addition to aqueous media�

Furthermore, no lateral minimum distances to tank walls and objects in the

tank are required

(→ 6 Installation)

4.2 Applications

•  Water, water-based media
•  Oils, oil-based media
•  Medium temperature 0…80 °C
•  Tank pressures: -0�5��4 bar
Application examples:
•  Detection of power steering oil
•  Monitoring of brake fluid
•  Detection of water-glycol mixtures
•  Monitoring of hydraulic oil in a hydraulic power unit
