Senator S80P FMCW 80GHz Radar for Powders and Fines

Senator S80P FMCW 80GHz Radar for Powders and Fines

The Senator S80P FMCW 80GHz Radar Level Transmitter is designed specifically to measure powders and dusty atmospheres. This device is a non-contact radar level transmitter that uses FMCW technology. It measures distance, level and volume of powders, granulates and other solids. It is ideal for measuring the level of solids in applications with very dusty atmospheres.

Principle of Operation

Frequency Modulated Continuous Wave (FMCW) technology features a continuous signal transmission, providing immediate measurement updates with zero delays. Unlike pulse radar, where the transmitter sends a pulse and then stop and waits for a reflection - FMCW radar emits a continuous signal. It determines the distance to the target by measuring the frequency difference between the emitted and the reflected signals. This frequency change is also called the "Doppler Shift" of the returned signal.



  • Accuracy ±2 mm / ±0.08"
  • 2-wire loop-powered 80 GHz transmitter HART 7
  • Extremely high dynamics with considerable signal-to-noise ratio for clear vision in dusty atmospher
  • Flush-mounted PEEK Lens antenna hence no intrusion into tank
  • Easy installation due to small beam angles
  • Tank or Vessel
  • Shaft
  • Other

Measuring Principle: 2-wire loop powered, FMCW Radar

Accuracy: Standard: ±2 mm / ±0.08, when distance < 10 m / 33 ft;
