FineTek JFR FMCW Radar Level Transmitter

FineTek JFR FMCW Radar Level Transmitter

The FineTek JFR Series brings non-contact radar accuracy to tanks, bins, and silos holding both liquids and bulk solids. Because the antenna never touches the material, it keeps performing reliably in demanding, high-accuracy applications where contact sensors would foul or wear.

How It Works

Running at either 10GHz or 26GHz, the transmitter sends an FMCW (frequency modulated continuous wave) signal from its antenna down toward the material surface. A portion of that signal reflects back after a short delay, and the frequency difference between the outgoing and returning signals maps directly to distance. The electronics process that difference into a highly linear, accurate level reading.

Key Features

  • Non-contact FMCW radar — no moving parts, no product contact
  • Available in 10GHz or 26GHz versions
  • Excellent linearity, with error as low as ±5 mm (0.197″)
  • Measures both liquids and bulk solids
  • Low maintenance even in dusty, corrosive, or abrasive service

Applications

  • Continuous level measurement in tanks, bins, and silos
  • High-accuracy inventory management
  • Dusty bulk solids and aggressive liquid service
