“Just give me the level!” Even the simplest user requests cannot always be easily fulfilled. However, a new level gauge based on the guided radar principle meets exactly this requirement thanks to self-learning signal processing and innovative algorithms.
Easier still! This basic requirement was the driving force behind the development of the new sensors of the Vegaflex 80 series. Besides the simple instrument selection and menu-guided setup, reliability and measurement certainty were the focus. The series consists of four different instrument types, each of which is tailored to a particular application. Vegaflex 81 is optimized for use in liquids, Vegaflex 82 is extraordinarily robust and ideal for bulk solids. When it comes to measurement of food or corrosive products, Vegaflex 83 meets the special requirements for hygiene and durability, with its resistant materials and high-quality surface finish. For extreme temperatures as well as high pressure applications, such as distillation columns, Vegaflex 86 is the optimal solution.
An example of this new development focus is the Vegaflex 82 for level measurement of bulk solids materials. The instrument can measure solids with a small dielectric constant, in measuring ranges up to 70 meters in metal or concrete silos, even during pneumatic filling. Vegaflex 82 comes in two versions: one with a 4 mm cable (tensile loads up to 500 kg) for free-flowing granules and heights of about 8 to 10 meters and one with a 6 mm cable (tensile loads up to 3 tons) for heavy powders and longer ranges.
Studies have shown that more than 20 % of all production disturbances or stoppages result from incorrect instrument setup and commissioning. That’s why the top priority for Vega was to make setup and commissioning as simple as possible. The user is guided through the set up, so that after only six steps, measurement with the instrument can begin. They only need to specify whether the application is in a metal or concrete container. The instrument itself takes care of the rest, setting all operating parameters.
Once Vegaflex 82 is electrically connected, it measures the level immediately. Potential entry errors are thus completely avoided. This is thanks to the large number of processes integrated in the sensor software. These not only facilitate setup and commissioning, but also ensure reliable measurement data and allow for a wider range of applications.
