  • Page 13: Mounting Instructions

    You can find detailed information on the process conditions in chapter "Technical data" as well as on the type label. Mounting instructions Installation position Mount SITRANS LG260 in such a way that the distance to vessel installations 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 Fig. 3: Installation in non-metallic vessel Flange Metal sheet Concrete vessel When installed in thick concrete ceilings, SITRANS LG260 should be mounted front flush to the lower edge. In concrete silos, the distance to the wall should be at least 500 mm (20 in). ø >160 mm (ø >6.3") Fig. 4: Installation in concrete silo Mounting socket If possible, avoid sockets. Mount the sensor flush with the vessel top. If this is not possible, use short sockets with small diameter.
  • Page 15 Fig. 6: Socket must be installed flush Unfavourable installation 2 Socket flush - optimum installation Welding work Before beginning the welding work, remove the electronics module from the sensor. By doing this, you avoid damage to the electronics through inductive coupling. Inflowing medium Do not mount the instruments in or above the filling stream. Make sure that you detect the product surface, not the inflowing product. PBD-51041057 SITRANS LG260 - Operating Instructions...
  • Page 16 If there is a danger of the rod probe touching the vessel wall, then the probe must be fastened at the bottom end. Keep in mind that below the fastening, a measurement is not possible. SITRANS LG260 - Operating Instructions PBD-51041057...
  • Page 17 Rod extension In case of difficult installation conditions, for example in a socket, the probe can be suitably adapted with a rod extension. To compensate for the resulting changes in signal runtime, let the instrument determine the probe length automatically. You can find further information in the supplementary instructions of the rod and cable components. PBD-51041057 SITRANS LG260 - Operating Instructions...
