NYRD701 1.8G Cable Antenna Guided Wave Radar Level Meter
NYRD701 1.8G Guided Wave Radar Level Meter Working Principle
The high-frequency microwave pulse sent by the guided wave radar propagates along the detection component (steel cable or steel bar). When encountering the measured medium, a sudden change in the dielectric constant causes reflection, 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 of the measured medium.

NYRD701 1.8G Guided Wave Radar Level Meter Design Features
◎ The guided wave radar material level meter adopts advanced microwave processing technology and unique Echo Discovery echo processing technology. With contact measurement, the measurement accuracy is high and the measurement is more accurate. At the same time, guided wave radar resists adhesion and is not affected by the external environment such as medium temperature and adhesion.
◎ Various process connection modes and detection component types make the 70X series guided wave radar level meter suitable for various complex working conditions and applications. Such as high temperature, high pressure and low dielectric constant media.
◎ It adopts pulse working mode, with extremely low emission power, and can be installed in various metal and non-metallic containers, without harm to human body and environment.
