    The optional mounting strap allows simple mounting of the instrument on a wall, ceiling or boom. Especially in the case of open vessels, this is a simple and effective way to align the sensor to the surface of the bulk solid material. The following versions are available: • Length 300 mm VEGAPULS 69 • Modbus and Levelmaster protocol...

    Nose for marking the direction of polarisation Information: When the housing is rotated, the direction of polarization changes and hence the influence of the false echo on the measured value. Please keep this in mind when mounting or making changes later. Installation position Mount the instrument at least 200 mm (7.874 in) away from the vessel wall. VEGAPULS 69 • Modbus and Levelmaster protocol...
  • Page 21 This applies particularly if buildup on the vessel wall is expected. In such cases, we recommend repeating the false signal suppression at a later date with existing buildup. Reference plane The measuring range of VEGAPULS 69 begins physically at the end of the antenna. The min./max. adjustment, however, begins at the reference plane. The reference plane is different depending on the sensor version.
  • Page 22 4 Mounting Fig. 15: Mounting of the radar sensor with inflowing medium Silo with lateral filling In bulk solids silos with lateral pneumatic filling the instrument should not be mounted above the filling stream, as the radar signal will be disrupted. The optimal mounting position is to the side of the filling aperture. To avoid heavy soiling, the distance to any filter or dust exhauster should be as large as possible. VEGAPULS 69 • Modbus and Levelmaster protocol...
  • Page 23 4 Mounting Fig. 16: Mounting of the radar sensor with inflowing medium Nozzle For nozzle mounting, the nozzle should be as short as possible and its end rounded. This reduces false reflections from the nozzle. With threaded connection, the antenna end should protrude at least 5 mm (0.2 in) out of the nozzle. Fig. 17: Recommended socket mounting with different versions of VEGAPULS Flange with lens antenna Plastic horn antenna Thread with integrated antenna system VEGAPULS 69 • Modbus and Levelmaster protocol...
  • Page 24 4 Mounting If the reflective properties of the medium are good, you can mount VEGAPULS 69 on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. Note: When mounting on longer nozzles, we recommend carrying out a false signal suppression (see chapter " Parameter adjustment"). You will find recommended values for socket heights in the following illustration or the tables. The values come from typical applications.
  • Page 25 The easiest way to align the device is with the optional swivelling holder. Determine the suitable inclination angle and check the align- ment with the alignment aid in the VEGA Tools app on the device. Alternatively, the angle of inclination can be determined using the following drawing and table.
