62 is optionally also available with antenna extension.
H ence the antenna length can be selected such that the antenna end
protrudes 10 mm (0.4 in) out of the socket.
A lign the sensor in liquids as vertical as possible to the product surface
to achieve optimum measuring results.

T he mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the microwave signals.
V essel installations such as, for example, ladders, limit switches,
heating spirals, struts, etc. can cause false echoes that get super-
imposed on the useful echo. Make sure when planning your measuring
site that the radar sensor has a "clear view" to the measured product.
I n case of existing vessel installations, a false echo storage should be
carried out during setup.
I f large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
S
mall, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.
