Product Introduction
The VEGA VEGAPULS 68 is a radar level sensor developed for continuous measurement of bulk solids under demanding process conditions. It is suitable for high silos, large bunkers, crushers, and industrial storage facilities where dust, high temperatures, or difficult operating environments can affect measurement performance.
Key Features
- Non-contact radar measurement minimizes wear and routine maintenance.
- Measuring range up to 75 m for large storage installations.
- 26 GHz operating frequency for continuous bulk-solid level monitoring.
- Wide process temperature range, from -196 to +450 °C, depending on configuration.
- High process pressure capability, up to 160 bar for suitable versions.
- Multiple antenna designs and materials to suit different installation and process requirements.
- Various signal outputs, including 4–20 mA/HART, PROFIBUS PA, and FOUNDATION Fieldbus, depending on the version.
Applications
- Coal silos and coal-handling systems in power plants
- Cement, clinker, and other building-material storage
- Large bulk-material silos and bunkers
- Stone crushers and aggregate-processing facilities
- High-temperature industrial processes and furnace applications
- Other demanding bulk-solids storage and handling systems
Technical Highlights and Selection Considerations
The VEGAPULS 68 offers a published measuring accuracy of ±2 mm and a beam angle of 3° or greater, depending on the antenna version. When selecting a sensor, consider the bulk material's properties, silo geometry, dust levels, process temperature and pressure, antenna type, and required output signal.
Product status: VEGA lists the VEGAPULS 6X as the successor to the VEGAPULS 68. For new projects, consider the successor; for existing installations, confirm model and configuration compatibility before ordering.
