Technology

Non-Contact Radar

Non-Contact Radar level transmitters are offered with various operating frequencies, each having their own advantages.

There are two types of Non-Contact Radar transmitters:

  • Frequency Modulated Continuous Wave (FMCW)
  • Pulse Burst Radar

FMCW devices transmit a continuous signal with a constantly changing frequency down toward the liquid. The detected difference in frequencies between the transmitted signal and return echo is proportional to the distance.

Pulse Burst Radar transmitters, the older of the two types, emit short bursts of energy to a liquid surface, and incorporate ultra-high-speed timing circuitry to measure the time of the return signal reflected off the liquid surface.  Distance is then calculated utilizing the equation:

Distance = C x Transit Time/2, (where C = Speed of Light)

  • Range up to 30 meters (100 feet)
  • 4-button keypad and graphic LCD allow for convenience viewing of configuration parameters and echo curve
  • Proactive diagnostics advise not only what is wrong but also offer troubleshooting tips

Options

  • SIL 2 suitable (92.3% SFF, with full FMEDA report available)
  • PACTware PC Program and enhanced DTMs for advanced configuration and troubleshooting
  • Available with HART® digital output

Operating principle

The Pulsar R80 is a top-mounted, downward-facing FMCW radar transmitter operating at 80 GHz. FMCW devices transmit a continuous signal with a constantly changing frequency down toward the liquid. The detected difference in frequencies between the transmitted signal and return echo is a function of the distance. Level is then calculated by factoring in tank height and other configuration information.
