The 25 GHz (K-band) 2290 Pulse Radars are the most
progressive non-contact level transmitter technology for
industrial processes. With an excellent accuracy,
compact antennas and a user-friendly set-up the 2290 is
an e ective, simple, low cost choice for demanding level
applications. GF’s new K-band radar featuring ±3 mm
(±0.1inch) accuracy and short dead band excels with its
full plastic housing. Its antenna range incorporates a
stainless steel horn and enclosed plastic tube choices.

The enclosed antenna versions can be replaced without
removing the antenna enclosure from the process. Local
programming of type 2290 is aided by a plug-in display
module. The signal processing algorithm of the 2290 is
based on years of experience with non-contact level
measurement making it an excellent choice for
applications simple and challenging alike.
