Measurement Technology

What measurement technology does the Rosemount 5408 Level Transmitter utilize?

The 2-wire Rosemount 5408 Level Transmitter employs FMCW (Frequency Modulated Continuous Wave) radar technology.

A continuous radar signal is transmitted with the frequency increasing over time, creating a “signal sweep”. This signal is reflected from the surface back to the antenna, and the level is calculated.

FMCW explanation
How does installing Rosemount 5408 Level Transmitter with FMCW radar technology benefit level measurement applications?

The Rosemount 5408 is optimized for best sensitivity in process applications. FMCW radar technology offers superior performance by continuously emitting and receiving radar signals, allowing for precise distance and level measurements that are unaffected by environmental conditions such as temperature, pressure, or dust.

FMCW explanation
What advantages does the Rosemount 5408 Level Transmitter with FMCW radar technology offer over traditional level measurement methods?

The Rosemount 5408 with FMCW radar technology provides non-contacting level measurement, with no direct contact with process media.
