  • Page 10: Principle Of Operation

    Area of application VEGAPULS 68 is a radar sensor in K-band technology for continuous level measurement of solids. A version of VEGAPULS 68 is available for each area of application. • The version with horn antenna is particularly suitable for measure- ment of virtually all bulk solids in small silos and vessels.

  • Page 12: Mounting

    Fig. 2: Measures against moisture ingress Measuring range The reference plane for the measuring range of the sensors is the lower edge of the flange or the seal surface of the thread. VEGAPULS 68 • Profibus PA...
  • Page 13 If the medium reaches the antenna, buildup can form on it and cause faulty measurements later on. Polarisation The emitted radar pulses of VEGAPULS 68 are electromagnetic waves. They thus have electrical and magnetical components that are perpendicular to each other. The polariation is defined by the direction of the electrical component.

  • Page 14: Mounting Preparations - Horn Antenna

    Information: This information applies only to special versions! VEGAPULS 68 is also available in versions where the antenna has a bigger diameter than the process fitting (thread, flange). The antenna must therefore be disconnected from the process fitting before mount- ing.

  • Page 15: Mounting Preparations - Parabolic Antenna

    Proceed as follows: 1. Clamp VEGAPULS 68 with the flange, e.g. in a bench vice 2. Hold the connection piece (3) with a wrench (spanner size 22) on the flattenings 3.

  • Page 16: Mounting Instructions

    4 Mounting Note: Take note for VEGAPULS 68 with rinsing air connection that the holes in the antenna and in the process fitting correspond. This ensures a sufficient air flow (the air is led through the holes to the feed system. A rinsing of the parabolic antenna in total is not intended).
  • Page 17 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 68 • Profibus PA...
  • Page 18 4 Mounting Fig. 9: Proposal for installation after orientation VEGAPULS 68 The angle of inclination depends on the vessel dimensions. It can be easily checked with a suitable level or water leve on the sensor. Tip: VEGA recommends the adjusting aid from VEGA line of accessory.
  • Page 19 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 68 • Profibus PA...
  • Page 20 Fig. 11: Recommended socket mounting If the reflective properties of the medium are good, you can mount VEGAPULS 68 on sockets which are higher than the length of the antenna. You will find recommended values for socket heights in the following illustration.
  • Page 21 The optimal mounting position is on the outer wall of the silo with the sensor directed towards the emptying aperture in the silo center. Fig. 13: Mounting of VEGAPULS 68 in multiple chamber silos VEGAPULS 68 • Profibus PA...
  • Page 22 4 Mounting Fig. 14: Orientation of VEGAPULS 68 for emptying in the silo center Vessel installations Silo installations such as e.g. ladders, level switches, struts, and also structured vessel walls, can cause false echoes that get superim- posed on the useful echo. The mounting location of the radar sensor should be a place where no installations cross the microwave signals.
  • Page 23 4 Mounting Tip: In case of extreme dust in the antenna system, VEGAPULS 68 is available with rinsing connection e.g. for air. The air is distributed via channels in the antenna system and keeps it virtually free of dust. Fig. 16: Purging air connection with horn antenna Fig.
  • Page 24 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 68 on a mov- able bracket, the max. measuring rate must be observed (see chapter "Technical data").
