DR7000 FMCW

Overview

The DR7000, an FMCW 26 GHz radar, offers state of the art design. The DR7000 is able to operate over a 2 GHz bandwidth: this ensures sharper resolution and higher accuracy. The higher signal dynamics of the DR7000 allow the accurate detection of even the smallest level changes. The DR7000 is a 2-wire device with easy navigation display and touch screen interface, which allows for easy configuration and set up. State of the art signal processing and a large bandwidth allow the DR7000 to determine the true level in the tank, even with agitated surfaces.

DR7000 Series 2-wire intrinsically safe design systems for the ultimate in false echo rejection, even with multiple blade set agitators
Antenna designs allow level measurements in liquids, slurries, solids and granular measurements to
