Tip:

The instrument is also optionally available with an antenna extension.

The antenna length can be selected (either ex works or later) to allow

the antenna to protrude slightly out of the end of the mounting socket.

Due to the antenna extension however, disturbing reflections are

generated in the close-up range. This can lead to an increase in the

required minimum distance, especially with poorly reflecting media

such as plastic powder. In practice, a cleanly constructed mounting

socket, if necessary with rounded edges, introduces fewer disturbing

influences than an antenna extension.

Align the sensor in liquids as vertical as possible to the product sur-

face to achieve optimum measurement.

The mounting location of the radar sensor should be a place where no

other equipment or fixtures cross the path of the microwave signals.
Vessel installations, such as e.g. ladders, limit switches, heating spi-

rals, struts, etc., can cause false echoes and impair the useful echo.

Make sure when planning your measuring site that the radar sensor

has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be

carried out during setup.
If large vessel installations such as struts or supports cause false

echoes, these can be attenuated through supplementary measures.
