Hot Sale 4-20mA Liquid 6GHz NYRD801 Radar Level Meter
6GHz NYRD801 Radar Level Meter Working Principle
Very short microwave pulses with very low energy are transmitted
and received through the antenna system. Radar waves travel at the
speed of light.The running time can be converted into level signal
through electronic components. A special time extension method can
ensure stable and accurate measurement in a very short time. Even
if there is false echo under complex working conditions, the echo
of material level can be accurately analyzed with the latest
microprocessor technology and debugging software.
Input:
The antenna receives the reflected micro pulse and transmits it to
the electronic circuit. The microprocessor processes the signal and
identifies the echo generated by the micro pulse on the material
surface. The correct echo signal recognition is completed by pulse
software, and the accuracy can reach millimeter level. The distance
D from the material surface is proportional to the pulse time
travel T: D=C×T/2(C is the speed of light)
Since the distance E of the empty tank is known, the material level
L is: L=E-D.
Output:
It is set by inputting empty tank height E (= zero point), full
tank height F (= full scale) and some application parameters. The
application parameters will automatically adapt the instrument to
the measurement environment, corresponding to 4-20mA output.
