VEGAPULS 21

Compact radar sensor for continuous level measurement

For standard measuring tasks, plastic housing IP66/IP67, Type 4X

Introduction Application Technical specifications Documentation

Application area

4 ... 20 mA/HART output, measuring range up to 20 m, accuracy ±2 mm, Ex approval optional

VEGAPULS 21 is the ideal sensor for non-contact level measurement of liquids and bulk solids in simple applications. It is particularly suitable for use in water treatment, storage tanks with acids, lyes and additives in all industrial areas, or for measuring levels in plastic tanks from the outside through the tank wall. In bulk solids the sensors are used in small bulk solids silos or open containers.
