OPTIWAVE 1400 C –
Focus is everything
OPTIWAVE 1400 C –
The FMCW radar with a sharp focus on liquids
Featuring a robust IP68 design with wetted parts made of stainless steel
and polypropylene (PP), this level transmitter perfectly fits the requirements of the water and wastewater industry.
Just like all previous non-contact radar transmitters from KROHNE, the
new OPTIWAVE 1400 C uses FMCW radar technology. Its proven PP Drop
antenna, with the smallest beam angle on the market, guarantees a sharp
focus on liquids, unsusceptible to condensation, turbulent surfaces or
foam.
Competitive in price, easy to install and operate, the OPTIWAVE 1400 C
ensures continuous level measurement without maintenance over a long
period of time.

Measuring principle
The radar principle used is called FMCW
(frequency modulated continuous wave).
An FMCW radar continuously emits a linear,
frequency-modulated signal with a constant amplitude (sweep). The distance to the
product is measured indirectly by using the
frequency difference between the emitted
and the received waves.
