    Note: Process conditions For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter " Technical data" of the operating instructions or on the type label. VEGAFLEX 82 • Two-wire 4 … 20 mA/HART...

  • Page 12: Mounting Instructions

    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 using the probes without metal vessel wall, e.g. in plastic vessels, the measured value can be influenced by strong electromag- netic fields (emitted interference according to EN 61326: class A). Use a probe in coax version for applications in liquids. VEGAFLEX 82 • Two-wire 4 … 20 mA/HART...
  • Page 13 4 Mounting Fig. 3: Mounting in non-metallic vessel Flange Metal sheet Concrete vessel When mounting in thick concrete ceilings, VEGAFLEX 82 should be mounted front flush to the lower edge. In concrete silos, the distance to the wall should be at least 500 mm (20 in). ø >160 mm (ø >6.3") Fig.

    Note: With power supply units with integrated HART resistance (internal resistance approx. 250 Ω), an additional external resistance is not necessary. This applies, e.g. to the VEGA instruments VEGAMET 381, VEGAMET 391. Common Ex separators are also usually equipped with a sufficient current limiting resistance. In such cases, the interface adapter can be connected parallel to the 4 … 20 mA cable (dashed line in the previous illustration).
