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.
In liquids, direct the sensor as perpendicular as possible to the prod-
uct surface to achieve optimum measurement results.
