    4 Mounting Fig. 2: Measures against moisture penetration The reference plane for the measuring range of the sensors is the Measuring range sealing surface of the thread or flange. Keep in mind that a min. distance must be maintained below the reference plane and possibly also at the end of the probe - measurement in these areas is not possible (dead band).
  • Page 13 4 Mounting keep in mind that measurement down to the tip of the probe is not possible. The exact value of the min. distance (lower dead band) is stated in chapter "Technical data". Fig. 3: Vessel with conical bottom Make sure that the probe is not subjected to strong lateral forces. Inflowing medium Mount VEGAFLEX 66 at a position in the vessel where no disturbances, e.g.
  • Page 14 4 Mounting 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 Standpipes or bypass tubes are normally metal tubes with a diameter Standpipes or bypass...
  • Page 15 4 Mounting Fig. 5: Position of the spacer Spacer Note: Measurement in a standpipe is not recommended for very adhesive products. If there is a danger of the probe touching the vessel wall during Fixing operation due to product movements or agitators etc., the measuring probe should be securely fixed.
