RIL400 radar level transmitter to 26 GHz two-wire for measuring ranges up to 20 m suitable for the continuous monitoring of even aggressive liquids in storage tanks, process vessels with agitators, vaporising liquids, substances with low dielectric constant, or suitable for small vessels, high and narrow.
This radar level transmitterhas on-board display with configurable keypad for programming.

With the 26 GHz frequency creates a narrow radar concentrated cone that allows the use of small antennas with a reduced sensitivity to fixed obstacles.
RIL400 fit perfectly with low dielectric constants and small containers as well as tall and narrow vessels.


  • The high frequency at 26 GHz allows the use of small antennas and the easy monitoring in the nozzles
  • Sensitivity to false echoes due to fixed obstacles
  • Dead reduced area for a minimum of up to 50 mm measuring range, improved (1" ½) from the antenna
  • Optional communication via HART®
  • By request Atex Exd or intrinsically safe feeder
