Model R82
Pulse Burst Radar
Level Transmitter
D E S C R I P T I O N
The Model R82 is an economical, loop-powered radar
transmitter bringing radar to everyday applications. Daily
applications that have been considered for Ultrasonic can
now use radar technology with its superior performance.
The electronics are housed in a compact, single com-
partment cast aluminum or Lexan
®
housing. The R82
measures effectively even when atmospheres above the
liquid are saturated with vapor. Pulse Burst technology
and advanced signal processing manage common distur-
bances such as false echoes caused by obstructions,
multi-path reflections from tank sidewalls or turbulence
caused by agitators, aggressive chemicals, or aerators.
T E C H N O L O G Y
Model R82 Pulse Burst Radar emits short bursts of
26 GHz energy. High-speed timing circuitry measures the
time of the signal reflected off the liquid surface.
Sophisticated signal processing filters out false reflections
and other background noises. The exact level is then
calculated, by factoring tank height and sensor offset
information. The Model R82 circuitry is extremely energy
efficient so no duty cycling is needed like with likewise
radars. This allows tracking of high rates of level change
up to 180"/min (4.5m/min).
