NYRD704 Radar Level Transmitter Working Principle
Guided wave radar emits high-frequency microwave pulses that travel along the detection component (steel cable or steel rod). When encountering the measured medium, part of the pulse energy is reflected back due to the sudden change of dielectric constant causing reflection. The time interval between the emitted pulse and the reflected pulse is proportional to the distance of the measured medium.
Input:
Guided wave radar is a measuring instrument based on the principle of time travel. The radar wave travels at the speed of light and the travel time can be converted into a level signal by the electronics. The probe emits a high frequency pulse and propagates it along a cable or rod probe. When the pulse encounters the material surface, it is reflected back and received by the receiver in the instrument, which converts the distance signal into a level signal.
The reflected signal is transmitted along the cable or rod probe to the instrument's electronic circuitry. The microprocessor processes the signal and identifies the echoes generated by the microwave pulse on the material surface.
The correct identification of the echo signal is done by the pulse software. The distance D to 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 from the empty tank is known, the material level L is:
L = E - D
Output:
It is set by entering the empty tank height E (= zero point), the full tank height F (= full scale) and some application parameters. The application parameters automatically adapt the instrument to the measurement environment and correspond to the 4-20mA output.
NYRD704 Radar Level Transmitter Design Feature
1.Intelligent radar level meter adopts advanced microwave processing technology and unique echo discovery echo processing technology. Contact measurement, high measurement accuracy, more accurate measurement. Meanwhile, the guided wave radar is anti-adhesive and not affected by external temperature such as medium temperature and adhesion.
2.A variety of process connection methods and detection element types make 70X series guided wave radar level meter suitable for various complex working conditions and applications. Such as high temperature, high pressure, low dielectric constant media.
3.Adopting pulse working mode, the product emits extremely low power and can be installed in various metal and non-metal containers, which is harmless to human body and environment.
