VEGAPULS 68

Radar sensor for continuous level measurement of bulk solids

In extreme temperatures and pressures


Application area

The extended selection of process fittings and materials allows use in extreme temperature and pressure ranges.
The VEGAPULS 68 is a radar sensor for continuous measurement of bulk solids also under difficult process conditions and with large measuring ranges. The sensor is ideal for level measurement in high silos, large bunkers, stone crushers and in the furnace. The VEGAPULS 68 with different antenna versions and materials is the optimum solution for virtually all applications and processes. Through the wide temperature and pressure range, the sensor can be used universally and enables a simple planning.

Your benefit

  • High plant availability, because wear and maintenance-free
  • Maintenance-free operation through non-contact measuring principle
  • Reliable measurement independent of vapour, dust and noise

Level monitoring of bulk solids – a tough instrument for tough environments

VEGAPULS 68 is the level measuring transducer for extreme bulk solids applications in silos of all kinds. Continuous monitoring of bulk solids with VEGAPULS 68 is largely independent of process conditions such as high temperatures or dusty environment, e.g. in coal handling systems in power plants or in storage facilities for building materials such as clinker or cement.
