    – If necessary, further certificates Principle of operation Application area The VEGAFLEX 83 is a level sensor with polished rod probe for continuous level or interface measurement, particularly suitable for applications in the food processing and pharmaceutical industry. Optionally an autoclaved version with separable housing is available.
  • Page 9 Functional principle - in- High frequency microwave impulses are guided along a steel cable or terface measurement rod. Upon reaching the product surface, a part of the microwave im- pulses is reflected. The other part passes through the upper product and is reflected by the interface. The running times to the two product layers are processed by the instrument. VEGAFLEX 83 • Foundation Fieldbus...

    The interface adapter VEGACONNECT enables the connection of communication-capable instruments to the USB interface of a PC. For parameter adjustment of these instruments, the adjustment software PACTware with VEGA-DTM is required.

You can find further information in the operating instructions "VE- GADIS 81" (Document-ID 43814).
  • Page 13 3 Product description You can find additional information in the operating instructions manual "External housing" (Document-ID 46802). Centering If you mount the VEGAFLEX 83 in a bypass tube or standpipe, you have to avoid contact to the bypass tube by using a spacer at the probe end. You can find additional information in the operating instructions manual "Centering".

  • Page 15 The guided microwave principle requires a metallic surface on the process fitting. Therefore, in plastic vessels, etc., use an instru- ment version with flange (from DN 50) or place a metal sheet (ø > 200 mm/8 in) beneath the process fitting when screwing it in. Make sure that the plate has direct contact with the process fitting. When installing rod or cable probes in vessels without metal walls, e.g. in plastic vessels, the measured value can be influenced by strong electromagnetic fields (emitted interference according to EN 61326: class A). In this case, use a probe with coaxial version. VEGAFLEX 83 • Foundation Fieldbus...
