  • 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 • Four-wire Modbus...
