DR7400 Radar Level Transmitter
Brand: DrexelbrookDrexelbrook DR7400 is a loop powered FMCW 26 GHz radar that offers State-of-the-Art components. The DR7400 operates over a larger bandwidth: This ensures excellent resolution and high accuracy in agitated and corrosive liquids.
The higher signal dynamics of the DR7400 allow the accurate detection of even the smallest level changes. Proven PTFE and PEEK Drop antenna with flange protection.
Due to the antenna design it is ideal for measurements up to 100 m / 328 feet. To ensure sharper resolution and higher accuracy this radar level transmitter can operate over a 2 GHz bandwidth, 24-26 GHz. The higher signal dynamics of the DR7400 allow the accurate detection of even the smallest level changes.
The DR7400 is a two-wire radar level measurement device with clear navigation display and touch screen user interface, which allows for easy configuration and set up.
A powerful signal processing and a large bandwidth allow this transmitter to determine the true level in the tank, even with agitated surfaces.
