Guided radar for level measurement of bulk solids
23 October 2012 - 940 views
SCHILTACH - For bulk solids, even those with low reflectivity and applications in silos up to 75 m high, the new guided radar sensor VEGAFLEX 82 with innovative features offers a new quality when it comes to reliability and measurement certainty.
Thanks to its new automatic probe end tracking function, VEGAFLEX 82 measures the levels of bulk solids even with a low dielectric constant of 1.1 and higher with unprecedented reliability. When there is an increasingly unreliable product signal, the sensor switches automatically to the stable probe end tracking signal, which is always proportional to the level. This guarantees accurate, consistent readings, especially with critical products such as plastic powder. The sensor is thus able to adapt to changing conditions, delivering a new quality in measurement certainty and reliability.
If large amounts of buildup form on the measuring probe, another innovative feature takes effect: dynamic false echo suppression. The signal processing system adapts itself automatically to the process conditions and increases measurement certainty even in such applications.
Standard features for universal use
VEGAFLEX 82 is suitable for level measurement in almost all bulk solids. It delivers reliable measurement data in process temperatures from -40 to +200° C and process pressures from -1 to +40 bar. Its applications range from large-volume bunkers to 75 m-high silos, from light, fine powders to coarse, heavy gravel. As a member of the plics family, the sensor combines all the advantages of VEGA’s sensor concept: robust designs in cable and rod versions, standardized process fittings and a wide variety of housing and electronics versions.
The VEGAFLEX 82 sensors are supplied already calibrated. For specific settings on site, the quick-start function guides the user through the setup menus in a few easy-to-follow steps.
VEGAFLEX 82 is equipped with asset management functions according to NE 107 for simple diagnostics and preventive maintenance. Beside the level, the instrument also continuously transmits the dielectric constant of the bulk material, giving an indication of its moisture content. In addition, measurement data, events and echo curves are stored permanently in the sensor electronics.
The sensors have of course all necessary approvals such as ATEX, FM and SIL2/3.
