  • Page 13: Mounting

    4.2 Instructions for installation Installation position Mount VEGAFLEX 83 in such a way that the distance to vessel instal- lations or to the vessel wall is at least 300 mm (12 in). In non-metallic vessels, the distance to the vessel wall should be at least 500 mm (19.7 in).
  • Page 14 If this is not possible, use short sockets with small diameter. Higher sockets or sockets with a bigger diameter can generally be used. They simply increase the upper blocking distance. Check if this is relevant for your measurement. VEGAFLEX 83 • 4 … 20 mA/HART - two-wire...
