    In such cases, we recommend repeating the false signal suppression at a later date with existing buildup. Inflowing medium Mounting should not be too close to the inflowing material as the microwave signal will be interferred. The optimum mounting position is on the opposite of the filling. To avoid strong pollution, the distance to the filter or dust extraction must be as big as possible. VEGAPULS SR 68 • 4 … 20 mA/HART - four-wire...
  • Page 20 4 Mounting Fig. 7: Mounting of the radar sensor with inflowing medium With bulk solids silos with lateral pneumatic filling, mounting should not be in the filling stream as the microwave signal will be interferred.

  • Page 22 When using a swivelling holder, keep in mind that the distance between antenna and socket gets smaller as the inclination of the sensor increases.

  • Page 23 The antenna length can be selected (either ex works or later) to allow the antenna to protrude slightly out of the end of the mounting socket. Due to the antenna extension however, disturbing reflections are generated in the close-up range. This can lead to an increase in the VEGAPULS SR 68 • 4 … 20 mA/HART - four-wire...

  • Page 26 In case of existing vessel installations, a false signal suppression should be carried out during setup. If large vessel installations such as struts or supports cause false echoes, these can be attenuated through supplementary measures. Small, inclined sheet metal baffles above the installations scatter the radar signals and prevent direct interfering reflections.
