Product Introduction
The VEGA VEGAPULS 21 is a compact radar sensor for continuous, non-contact level measurement. It uses 80 GHz radar signals to determine the distance to the material surface, making it suitable for standard applications involving liquids and bulk solids.
Key Features
- 80 GHz Radar Technology: Enables precise, non-contact level measurement.
- Measuring Range up to 20 m: Suitable for a variety of tanks and storage vessels.
- High Accuracy: Measurement deviation up to ±2 mm under specified conditions.
- 4–20 mA/HART Output: Supports integration with industrial control systems.
- Bluetooth® Configuration: Allows convenient setup using compatible mobile devices or PCs.
- Rugged Housing: IP66/IP67 protection and Type 4X enclosure rating for demanding environments.
- Chemical Compatibility: PVDF wetted parts and FKM sealing, subject to application compatibility.
Applications
- Water and Wastewater Treatment: Monitoring levels in sumps, treatment tanks, and water storage systems.
- Chemical Storage Tanks: Measuring compatible acids, alkalis, and chemical additives.
- Plastic Tanks: Supports level measurement through suitable plastic tank walls in applicable installations.
- Industrial Liquid Storage: Continuous monitoring in process tanks and storage vessels.
- Bulk Solids: Level measurement in small silos and open containers containing suitable bulk materials.
Technical Highlights and Selection Considerations
The VEGAPULS 21 combines compact construction with non-contact radar measurement, reducing maintenance associated with sensors that contact the medium. Its narrow 8° beam angle helps focus the radar signal in suitable installation conditions.
When selecting a model, confirm the measuring distance, tank geometry, process temperature and pressure, material compatibility, mounting position, and required approvals. The published process temperature range is -40 to +80°C, and process pressure is -1 to +3 bar. Verify the exact configuration before ordering.
Frequently Asked Questions
Q1: What is the VEGA VEGAPULS 21 used for?
It provides continuous, non-contact level measurement for liquids and suitable bulk solids in tanks, sumps, and storage vessels.
Q2: What is the maximum measuring range?
The specified measuring range is up to 20 m, depending on the application and configuration.
Q3: Can the VEGAPULS 21 measure aggressive chemicals?
It can measure compatible chemicals when the PVDF wetted parts and FKM seal are suitable for the process medium. Check chemical compatibility before installation.
Q4: Does the VEGAPULS 21 support HART communication?
Yes. It uses a 4–20 mA/HART output and also supports Bluetooth® configuration with compatible devices.
Q5: Can it measure level through a plastic tank wall?
In suitable applications, it can measure from outside a plastic tank. The tank material, wall thickness, mounting position, and radar signal path must be suitable for reliable measurement.
