IP67 No Mixing Of Liquid, Dust NYRD702 Guided Radar Level Transmitter
NYRD702 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:
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.
NYRD702 Guided Radar Level Transmitter Design Feature
1.The intelligent radar level meter adopts advanced microwave processing technology and unique echo discovery echo processing technology. Contact measurement, high measurement accuracy, more accurate measurement. At the same time, the guided wave radar is resistant to adhesion and is not affected by external temperature such as medium temperature and adhesion.
2.A variety of process connection modes and types of detection components make 70X series guided wave radar level meters suitable for various complex working conditions and applications. Such as high temperature, high pressure and low dielectric constant media.
3.With pulse working mode, the product has extremely low emission power and can be installed in various metal and non-metal containers, without harm to human body and the environment.
