Stopping the flow at the right time
Vega sensors have been essential in monitoring the production of juice at the Ceres fruit juice manufacturers in the Western Cape for many years. Therefore, the company jumped at the chance to test out the latest sensor in the Vegapoint series for capacitive point level measurement. Claudia Homburg looks at the new innovation.

INTRODUCING THE NEW SENSOR IN TOWN The new Vegapoint 21, which was first introduced at the Ceres juice company, is a level switch with adjustable switching point for detection of water-based liquids. The sensor and the tank form the two electrodes of a capacitor. Any change in capacitance due to a level change is converted into a switching signal.
ADVANTAGES OF THE NEW SENSOR AT CERES There were many advantages to using this
"The Vegapoint 21 proved to be extremely easy to use in practice with the sensor working even under difficult measuring conditions, which is essential for fruit juice manufacturers."
APPLICATIONS FOR USE OF THE VEGAPOINT SERIES Sensors of the Vegapoint series can be used for overfill and dry run protection as well as oil/water and foam detection. The optional universal connector with hygienic adapter ensures reduced installation costs and a smaller spare parts inventory. The series meets the requirements of hygienic processes in the food, beverage and pharmaceutical industries. Additionally, the small level switch version has a compact stainless-steel housing and is available in two electronics versions: simple transistor output and transistor output with additional digital IO-Link communication.

The colourful, all-round switching status display of the Vegapoint 21 also allows quick and easy recognition of the switching status. With it the user can keep an eye on the status of the tank at all times. This came in handy for the workers at the fruit juice company as it allowed them to concentrate on other tasks in juice production without having to worry about something going
