Instrument Knowledge beam angle of 26GHz radar level sensor

Page view

Radar level sensor, the electromagnetic wave can pass through the vacuum when measuring, no need transmission medium, won’t be affected by air, steam, volatile medium, it has high frequency electromagnetic wave and strong penetrating energy, even the solid silo has small dimension and stong dusty condition, the radar level sensor can provide continuous, reliable and stable measuring results.


Hebei Huachuang M&C Technology Co.,Ltd

Specialized in the R&D of level measuring instruments for materials, liquids, hydrology.

High frequency, has advantage for the measurement of solid and low DK value mediums:

1.Non-contact radar, wear-free, no pollution.

2.Small antenna, easy toinstall.

3.Shorter wavelength could get better reflected wave on the solid surface with inclination.

4.Smaller dead band, could get good measuring result even for small dimension tank.

5.Hardly affected by the corrosion or foam.

6.High signal-to-noise ratio, could get better performance even in the fluctuation condition.

7.Almost not affected by the water vapor,temperature and pressure change in atmosphere.

8.Heavy dusty condition won’t affect the working of electomagnetic wave. 

9.26G high freqneucy intelligent radar level sensor

10.Non-contact type measurement,  anti-corrosive,  pressure resistant. 

11.Anti-corrosive and explosion proof,  widely applicable , easy installationMaintenance free, low power consumption,  high accuracy.


26GHz radar level sensors from HCCK , each type of sensor has different dimension of antenna, sothe beam angle will be different. Now, let’s see some details :



















According to the different measuring range, the widths of electromagnetic wave are different also. The formula is :  

W = tan ( beam angle/2) * range * 2.
