Extremely short microwave impulses with low emitted power in the C-band and K-band frequency range are emitted by the professional antenna system to the measured product, reflected by the product surface and received again by the antenna system. They spread with light velocity and the time from the emission to receipt of the signals is proportional to the level in the vessel. A special time spreading procedure enables a reliable and precise measurement of extremely short time periods.
By simply entering the vessel dimensions, a level-proportional signal can be displayed. An adjustment with emptied and filled vessel is no longer necessary!
The spreading of microwaves is virtually not affected by the ambient temperature and ambient pressure. Radar detection are ideal for use under arduous process conditions. Pressures from vacuum to 160 bar and temperatures between -40 and 400°C are no problem for a radar level measuring.
Fluctuating product compositions or complete changes of the product do not influence the measurement result. A new adjustment is not necessary.
