Rosemount 5400

The Rosemount 5400 is touted as the first radar transmitter to offer peak performance in all three areas vital to radar level measurement: Echosensitivity — the ability to detect weak radar echoes reliably; Echodynamics — the ability to handle weak and strong radar echoes simultaneously; and Echologics — the ability to ignore false echoes. Two models are available — the Rosemount 5401, low-frequency transmitter (~ 6 GHz), which is used in applications with turbulence, heavy vapors, foam or where there is a risk for deposits on the antenna and the Rosemount 5402, high-frequency transmitter (~ 26 GHz), which utilizes a narrower radar beam for installations that have tall or narrow nozzles, where the nozzle is close to the tank wall, or to avoid disturbing objects in the tank.
