Magnetostrictive Level Transmitters

Pulsar® model R96- 6 GHz non-contact radar transmitter

Pulsar® model R96- 6 GHz non-contact radar transmitter

The Pulsar® Model R96 is a loop-powered, 24 VDC, non-contact radar level transmitter. It has a longer measurement range, improved diagnostics and is easier to use than most loop-powered radar transmitters.

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:

  1. Frequency Modulated Continuous Wave (FMCW)
  2. 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)
