The Pulsar® Model R86 non-contact radar level transmitter is a 24 VDC, liquid level transmitters. It has a longer measurement range, circular polarization, advanced diagnostics and is easier to use than most loop-powered radar transmitters.
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,
