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 set of advantages.
There are two basic types of Non-Contact Radar transmitters, regardless of the frequency of operation:
- Frequency Modulated Continuous Wave (FMCW)
- Pulse Burst Radar
FMCW devices transmit a continuous signal with a constantly changing frequency down toward the process medium. 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 the surface of the process medium, and incorporate ultra-high-speed timing circuitry to measure the transit time of the reflected signal. Distance is then calculated utilizing the equation:
Distance = C x Transit Time/2, (where C = Speed of Light)
