NYRD701 Guided Radar Level Transmitter Working Principle

The high-frequency microwave pulse sent by the guided wave radar propagates along the detection component (steel cable or steel rod). When encountering the measured medium, it causes reflection due to sudden change of dielectric constant, and part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance from the measured medium.

Input:

Guided wave radar is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into material level signal through electronic components. The probe sends out high-frequency pulse and propagates along the cable or rod probe. When the pulse meets the material surface, it is reflected back and received by the receiver in the instrument, and the distance signal is converted into material level signal.

The reflected signal is transmitted to the electronic circuit of the instrument along the cable or rod probe. The microprocessor processes the signal and identifies the echo generated by the microwave pulse on the material surface. The correct echo signal recognition is completed by pulse software.

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.
