52. ubes Excessive system vibration or shocks e g caused by agitators or turbulence in the vessel e g from fluidisation can cause the coax probe of VEGAFLEX 66 to vibrate in resonance Should a coax probe of more than 1 m 3 281 in length should be used you can provide a suitable support or guy directly above the end of the probe to stabilise it Standpipes or bypass tubes are normally metal tubes with a diameter of 30 200 mm 1 18 7 87 in In measurement technology such a tube corresponds to a coax probe It does not matter if the standpipe is perforated or slotted for better mixing Lateral inlets with bypass tubes also do not influence the measurement Measuring probes can be mounted in bypass tubes up to DN 200 The max temperature is 250 C 482 F If VEGAFLEX 66 is used in standpipes or bypass tubes contact with the tube wall should be avoided We offer spacers as accessories for fastening the probe in the middle of the tube Depending on the tube diameter or tube length one or several spacers can be mounted With cable probes the cable can also be strained to avoid contact with the tube The max temperature for the spacers is 250 C 482 F A special high temperature version of VEGAFLEX 66 with integrated bypass tube can be used in applications with temperatures up to 400 C 752 F Keep in mind that buildup can form on the spacers Strong buildup can influence the measurement 14 VEGAFLEX 66
