    The instrument is also available in versions with an antenna whose diameter is larger than the process fitting (thread, flange). In such cases the antenna must be disconnected from the process fitting before mounting. Proceed as follows: 1. Loosen the hexagon socket screws (3) on the antenna socket with an Allen wrench (size 3) 2. Remove the antenna (4) VEGAPULS SR 68 • Modbus and Levelmaster protocol...

    4. Loosen compression nut (2) completely with a wrench (width across flats 41 mm) in the direction of the antenna 5. Remove the parabolic antenna (4) axially 6. Mount sensor flange on the adapter flange and fasten it tightly 7. Check if the O-ring seal is present on the connection piece and make sure it is not damaged.

  • Page 14: Mounting Instructions

    Locknut Parabolic antenna Mounting instructions Polarisation The emitted radar impulses of the radar sensor are electromagnetic waves. The polarisation is the direction of the electrical wave compo- nent. By turning the instrument in the connection flange or mounting boss, the polarisation can be used to reduce the effects of false echoes. The position of the polarisation is marked on the process fitting of the instrument. VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 15 In such a case, it is recommended to repeat the false signal storage 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 • Modbus and Levelmaster protocol...
  • Page 16 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. The optimum mounting position is next to the filling. To avoid strong pollution, the distance to the filter or dust extraction must be as big as possible. VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 17 4 Mounting Fig. 8: Mounting of the radar sensor with inflowing medium Socket The socket piece should be dimensioned in such a way that the antenna end protrudes slightly out of the socket. VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 18 When using a swivelling holder, keep in mind that the distance between antenna and socket gets smaller as the inclination of the sensor increases. Additional false reflections may be generated which can influence the measuring result at close range. Fig. 11: Distance between antenna and socket with horn antenna VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 19 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 • Modbus and Levelmaster protocol...
  • Page 20 If mounting in the centre of the silo is not possible, the sensor can be directed to the vessel center by using the optional swivelling holder. The following description shows a simple way to determine the required angle of inclination. VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 21 In a vessel 20 m high, the installation position of the sensor is 1.4 m from the vessel centre. The necessary angle of inclination of 4° can be read out from this chart. VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 22 Small, inclined sheet metal baffles above the installations scatter the radar signals and prevent direct interfering reflections. Fig. 16: Cover smooth profiles with deflectors Agitators If there are agitators in the vessel, a false signal suppression should be carried out with the agitators in motion. This ensures that the interfering reflections from the agitators are saved with the blades in different positions. VEGAPULS SR 68 • Modbus and Levelmaster protocol...
  • Page 23 Fig. 18: Radar sensors on traverse crane Information: Keep in mind that for these applications, the sensors are designed for relatively slow level changes. When using VEGAPULS SR 68 on a movable bracket, the max. measuring rate must be observed (see chapter "Technical data").
  • Page 24 This can be avoided by using a sensor with aluminium or stainless steel housing. Mounting in multiple The silo walls of multiple chamber silos are often made of profile chamber silo walls, such as e.g. profile sheeting, to ensure the required stability. If the radar sensor is mounted very close to a heavily structured vessel wall, considerable false reflections can be generated. Hence the sen- VEGAPULS SR 68 • Modbus and Levelmaster protocol...
