Radar level sensor VP21

Type VP21


Application area

Compact radar sensor for continuous level measurement

4 ... 20 mA/HART output, measuring range up to 15 m, accuracy ±2 mm, Ex approval


VP21 is the ideal radar level 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.
