NYRD705 Rod Type Guided Wave Radar Level Transmitter Working
Principle
Input:
Guided wave radar is a measuring instrument based on the principle
of time travel. The radar wave operates at the speed of light,and
the operating time can be converted into a level signal through
electronic components. The probe sends out high-frequency pulses
and propagates along the cable or rod probe. When the pulses meet
the material surface, they are reflected back and received by the
receiver in the instrument, and the distance signal is converted
into the level signal.
The reflected pulse signal is transmitted to the electronic circuit
of the instrument along the cable or rod probe. The microprocessor
processes the signal and recognizes the echo generated by the
microwave pulse on the material surface. The correct echo signal
identification is completed by the pulse software. The distance D
from the material surface is proportional to the time travel T of
the pulse: D=C×T/2 (where C is the speed of light). Since the
distance E of the empty tank is known, the level is: L=E-D
Output:
By entering empty tank height E(= zero), full tank height F(= full
range) and some application parameters, the application parameters
will automatically adapt the meter to the measuring environment,
corresponding to 4-20mA output.
