80GHz Radar Level Gauge
Basic principle
- FMCW(Frequency Modulated Continuous Wave) Radar
- Distance=(Lightspeed×Delay time)/2
Excellence
- Non-contact radar is a top-down, direct measurement method because of its distance to the surface
- No need to compensate for changes in density, dielectric or conductivity of the liquid
- Even when the pressure, temperature, and conditions of most of the vapor space change, the accuracy is not affected
- Maintenance is minimized because radar equipment does not have any moving parts
- Non-contact radar devices can be separated from the process using PTE seals or valves
- It is suitable for corrosive or polluting environment because it does not touch the measuring medium
Key Performance
- FMCW, 80GHz band, Measuring Range100m max., Accuracy±2mm
The IUPLUS radar sensor module uses the frequency of the EHF (Extremely High Frequency) band, which is very short, making it useful for tank level measurement applications that can measure through snow, rain, fog, clouds, dust or water vapor.
In the limestone process, spectral process, and powder coal process, it is measured by penetrating dust when filling the tank, and furthermore, it is used for accurate tank level measurement since it is less affected by spot diffusion in ultrasonic waves or other band radar waves 6GHZ, 26GHZ. It's possible.
