Product Description

The VEGA VEGAPULS 21 Radar Level Sensor is a compact and cost-effective solution for non-contact continuous level measurement in liquids and bulk solids.

Using advanced 80 GHz radar technology, it provides highly accurate and stable measurements even in environments with vapor, condensation, or changing process conditions. The sensor is widely used in water treatment systems, chemical storage tanks, and small industrial silos where reliable industrial level measurement is required.

With maintenance-free operation and strong resistance to environmental interference, VEGAPULS 21 is an ideal replacement for traditional ultrasonic or mechanical level measurement devices. It supports easy integration into PLC and DCS systems via 4–20 mA/HART output.
