Measuring
principle Extremely short microwave impulses with low emitted power in the C-band and K-band frequency range are emitted by the 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. Latest microprocessor technology and the proven ECHOFOX® software select the level echo reliably from a number of false reflections and the echo is measured exactly. By simply entering the vessel dimensions, a level-proportional signal can be displayed. An adjustment with emptied and filled vessel is no longer necessary! Unaffected by temperature and pressure The spreading of microwaves is virtually not affected by the ambient temperature and ambient pressure. Radar sensors 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 measurement. Unaffected by product properties Fluctuating product compositions or complete changes of the product do not influence the measurement result. A new adjustment is not necessary. |
