    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 • 4 … 20 mA/HART two-wire VEGAPULS 68 • 4 … 20 mA/HART two-wire...
  • Page 8: Mounting Preparations - Horn Antenna

    This information applies only to special versions! the polarisation plane is marked on the instrument. 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 mounting.

    10 Tighten locknut (2) with SW 36, torque max. 40 Nm. 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).
