Product Introduction

The VEGA VEGAFLEX 83 is a guided wave radar transmitter for continuous liquid-level and interface measurement in hygienic and chemically demanding applications. It guides microwave pulses along a probe and evaluates their reflections to determine the liquid level or the boundary between two liquids. Its specialized probe designs support applications requiring high cleanability or resistance to aggressive media.

Key Features

  • Guided wave radar (TDR) technology for continuous level and interface measurement.
  • Measuring range up to 32 m for suitable configurations.
  • Measurement accuracy of ±2 mm, according to published product data.
  • PFA-coated or polished stainless steel probes for different process requirements.
  • Reliable measurement in applications involving foam, vapor, condensation, or product buildup.
  • Hygienic design options for food and pharmaceutical processes.
  • Process temperature range from -40 to +150 °C.
  • Multiple communication options, including 4–20 mA/HART and selected fieldbus versions, depending on configuration.

Applications

  • Level measurement in food and beverage tanks
  • Milk storage and processing vessels
  • Pharmaceutical and sterile process containers
  • Acid and corrosive-liquid storage tanks
  • Chemical processing vessels
  • Hygienic filling and batch-processing systems
  • Liquid interface measurement in compatible applications

Technical Highlights and Selection Considerations

The VEGAFLEX 83 supports process pressures from -1 to +16 bar, with a maximum measuring range of 32 m. Available probe designs include PFA-coated rods, polished or electropolished stainless steel rods, and PFA-coated cable probes. Wetted materials and seals vary by configuration.

When selecting a transmitter, consider the liquid's chemical compatibility, hygiene requirements, cleaning or sterilization procedures, tank geometry, probe length, process temperature and pressure, and required output signal. For food and pharmaceutical applications, verify the required hygienic approvals and suitability of all wetted materials.
