4 Functions and features

The unit continuously detects the level in tanks and generates output signals ac-
cording to the parameter settings�
4 switching outputs are available� They can be set separately�
For correct function the unit needs a large enough metal launching plate� It
is necessary for transferring the microwave pulse to the tank with optimum
transmission power�
The flange plates that are available as accessories are not sufficient as
launching plates (for suitable launching plates → 6.4).
For installation in closed metal tanks, the tank lid serves as a launching
plate� For installation in open metal tanks, tanks made of plastic or metal
tanks with plastic lids a sufficiently large fixing plate, a metal plate or simi-
lar must be used (→ 6.4.3 / 6.4.4).
Furthermore, minimum distances to tank walls, objects in the tank, bottom
of the tank and further level sensors must be adhered to (→ 6.1.1).
4.1 Applications
• Water, water-based media
• Medium temperature 0...80 °C (permanent); 0...90 °C (peak)
• Tank pressures: -1���4 bar
Application examples:
• Detection of coolant emulsion in a machine tool�
• Detection of cleaning liquid in a parts cleaning system�
4.1.1 Restriction of the application area
• The unit is not suitable for media with a dielectric constant < 20 (e�g� oils, fats,
plastic granulates, bulk material)�
• If the unit is to be used in acids or alkalis, in hygienic areas or in electroplating
applications: first check the compatibility of the product materials (→ 13 Techni-
cal 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�
