FineTek JFR4 FMCW Radar Level Transmitter

FineTek JFR4 FMCW Radar Level Transmitter

High temperature, high pressure, and corrosive process conditions are where a lot of level sensors give up — the FineTek JFR4 FMCW radar level transmitter is built to keep working through all three, without ever touching the product it’s measuring. It installs easily, runs maintenance-free, and holds its accuracy in demanding duties that call for a sensor you can trust.

How It Works

FMCW (frequency modulated continuous wave) radar sweeps a continuous high-frequency signal from the antenna toward the product surface. The reflected signal comes back at a slightly different frequency, and that frequency difference is directly proportional to the measured distance — delivering precise, stable level readings without any contact with the medium.
