    Keep in mind that measurement all the way down to the tip of the probe may not be pos- sible. The exact value of the min. distance (lower blocking distance) is stated in chapter " Technical data" of the operating instructions. VEGAFLEX 83 • Two-wire 4 … 20 mA/HART SIL...
  • Page 8 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 mounting 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. Fig. 3: Mounting in non-metallic vessel Flange Metal sheet Nozzle If possible, avoid nozzles. Mount the sensor flush with the vessel top. If this is not possible, use short nozzles with small diameter. VEGAFLEX 83 • Two-wire 4 … 20 mA/HART SIL...
