APPLICATION EXAMPLE
The minimum distance from the antenna face to the target
is limited by the near blanking, P800.
The application is to obtain a level measurement and corresponding 4-20 mA
output proportional to material levels in a chemical tank. The antenna flange is
5 m from the tank bottom. The empty level is 0 m (bottom) and the full level
(span) is 4.5 m from the bottom. The maximum rate of filling or emptying is about
1 m/min. In the event of a loss of echo, the IQ Radar 160 is to go into fail-safe low
after 2 minutes.
