Shanghai Yichuan Radar Level Gauge (Instrument)

1、 Product Overview

Shanghai Yichuan Radar Level GaugeMeasuring distances up to 50 meters. The antenna has been further optimized and processed, and the new fast microprocessor can perform higher speed signal analysis and processing, making the instrument suitable for very complex measurement conditions such as reaction vessels or solid material silos.

2、 Measurement principle

Shanghai Yichuan Radar Level GaugeThe antenna emits narrow microwave pulses, which are transmitted downwards through the antenna. After touching the surface of the measured medium, the microwave is reflected back and then received by the antenna system, which automatically converts it into a level signal and transmits it to the electronic circuit section. Due to the extremely fast propagation speed of microwaves, the time it takes for electromagnetic waves to reach the target and reflect back to the receiver is almost instantaneous. The schematic diagram is as follows.

4、 Performance characteristics

1. Small beam angle, concentrated energy, stronger anti-interference ability, greatly improving measurement accuracy and reliability;

2. The antenna size is small, making it easy to install and install antenna protective devices such as dust covers;

3. The measurement blind spot is smaller, and it can also achieve good results for measuring small cans;

4. Shorter wavelength makes it more suitable for level measurement of small particulate matter.

5. By adopting advanced microprocessor technology, the radar level gauge can be applied to various complex working conditions.

6. Using pulse working mode, the radar level gauge has extremely low transmission power and can be installed in various metal and non-metal containers.
