  • Page 13 NivoGuide® 8200 • Two-wire 4 … 20 mA/HART 4 Mounting Type of vessel Plastic vessel/Glass vessel 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).

Keep in mind that a min. distance must be maintained below the refer- ence plane and possibly also at the end of the probe - measurement in these areas is not possible (dead zone). The length of the cable can be used all the way to the end only when measuring conductive products. These dead zones for different mediums are listed in chap-...

If durability is no problem, we recommend the use of uncoated metal standpipes. When the NivoGuide 8200 is used in bypass tubes, contact with the tube wall must be avoided.
  • Page 17 NivoGuide® 8200 • Two-wire 4 … 20 mA/HART 4 Mounting Note: Measurement in a standpipe is not recommended for extremely adhe- sive products. In case of slight buildup, you should choose a bypass tube with bigger diameter. Instructions for the measurement: •...
