Product Description

The VEGA VEGAPULS C21 Radar Level Sensor is a compact 80 GHz non-contact device designed for continuous level measurement in liquids and light bulk solids.

With its integrated cable outlet design, it is ideal for installations in water treatment systems, pumping stations, stormwater basins, and small industrial tanks where space is limited. The sensor delivers highly accurate readings even under challenging environmental conditions such as vapor, condensation, or light turbulence.

Thanks to its maintenance-free radar technology, VEGAPULS C21 provides stable long-term operation without wear or calibration drift. It integrates easily into automation systems via 4–20 mA/HART or digital communication interfaces, making it a cost-effective solution for standard industrial level monitoring.
