Radar level sensor VC21

Type VC21

Wired radar sensor for continuous level measurement


Application Area

Axial cable outlet, measuring range up to 15 m, accuracy ±2 mm, 4 ... 20 mA, HART, SDI-12 or Modbus output, Ex-approval
Radar level sensor VC21 is the ideal sensor for non-contact level measurement in simple applications where a high degree of protection is required.
It is particularly suitable for use in water treatment, pumping stations and rain overflow basins, for flow measurement in open channels and level monitoring. In bulk solids the sensors are used in small bulk solids silos or open containers.
