The RD8X series radar sensor is a 26Ghz or 80Ghz high frequency microwave pulse radar level gauge. An electromagnetic wave of about 11 mm is emitted through the radar antenna system, and reflection is formed on the material surface by focusing of the bell antenna. The reflected echo is received through the antenna system. Since the transmission speed of electromagnetic waves is equivalent to the speed of light, it is almost instantaneous to transmit to reception. The radar transmits and receives about 80 times per second. Through the microprocessor of the radar control system, the time difference of the transmitted wave to the received wave is accurately calculated by calculating the average value. The calculation of the internal software is used to convert the radar zero point to the material. The empty height of the bit. Thereby a continuous measurement of the material level is achieved. Output 4-20MA analog current signal, directly access to the automation system (such as PLC / DCS / digital display, etc.) to achieve automatic control of tank level.

The radar level antenna transmits a narrower microwave pulse and is transmitted downward through the antenna. After the microwave contacts the surface of the measured medium, it is reflected back and received by the antenna system again. The signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the microwave propagation speed is extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver. The time used is almost instantaneous). Millimeter wave radar. It has the characteristics of narrow antenna beam, high resolution, frequency bandwidth and strong anti-interference ability.

Features：

Small antenna size for easy installation; non-contact radar, no wear, no pollution.

Almost free from corrosion and foam; almost unaffected by changes in water vapor, temperature and pressure in the atmosphere.

Severe dust environment has little effect on the work of high frequency level gauge.

Shorter wavelengths for better reflection on sloping solid surfaces.

The beam angle is small, the energy is concentrated, and the echo capability is enhanced while avoiding interference.

The measurement blind zone is smaller, and it will also achieve good results for small can measurement.

High signal-to-noise ratio for better performance even under fluctuating conditions.

High frequency, the best choice for measuring solid and low dielectric constant media.
