VEGAPULS C 21 radar level sensor

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 optional

VEGAPULS C 21 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.
