VEGAPULS C 21

Wired radar sensor for continuous level measurement

For standard measuring tasks, IP66/IP68, Type 6P

Application area

Axial cable outlet, measuring range up to 20 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.

Your benefit

  • Exact measurement results independent of medium, process and environmental conditions
  • Maintenance-free operation due to non-contact 80 GHz radar technology
  • High accuracy and reliability

Suitable accessories

Mounting bracket with adjustable sensor holder

Mounting bracket for ceiling mounting

Mounting angle with adjustable bracket
