Product Introduction
The VEGA VEGABAR 86 is a submersible pressure transmitter for continuous hydrostatic level measurement. It uses a ceramic CERTEC® measuring cell to measure liquid pressure and convert it into a signal for determining liquid level. When combined with another compatible VEGABAR Series 80 sensor, it can also support electronic differential pressure measurement.
Key Features
- Ceramic CERTEC® Measuring Cell: Offers high overload resistance and long-term stability.
- Front-Flush Design: Helps minimize deposits on the measuring diaphragm.
- Flexible Installation: Available with suspension cable or tube versions for different installation depths.
- Chemical Compatibility: Suitable materials are available for water, acids, alkalis, and other compatible liquids.
- Multiple Output Options: Depending on configuration, available outputs include 4–20 mA, HART®, PROFIBUS PA, FOUNDATION Fieldbus, and Modbus.
- Electronic Differential Pressure: Can be paired with another compatible VEGABAR Series 80 sensor for additional measurement applications.
Applications
- Water and Wastewater Treatment: Level monitoring in wells, wastewater shafts, basins, and reservoirs.
- Chemical Processing: Measuring liquid levels in tanks containing compatible acids, alkalis, and process chemicals.
- Water Supply Systems: Monitoring water levels in wells and open storage tanks.
- Industrial Liquid Storage: Continuous level measurement in open vessels and process basins.
- Special Differential Pressure Applications: With a compatible secondary sensor, supports applications such as level difference, flow, density, and interface measurement.
Technical Highlights and Selection Considerations
The VEGABAR 86 combines a robust ceramic sensor with flexible submersible installation. The published measuring range extends up to 25 bar, with a stated accuracy of 0.1% for the listed product specification. Maximum sensor length is up to 250 m for cable versions and 6 m for tube versions, depending on configuration.
When selecting a model, confirm the liquid properties, measurement depth, process temperature, cable or tube length, wetted materials, output signal, and required approvals. Ensure that seal and housing materials are compatible with the application.
