    NivoGuide® 8100 • Two-wire 4 … 20 mA/HART 4 Mounting Mounting General instructions Screwing in On devices with a threaded fitting, the hexagon on the process fitting must be tightened with a suitable wrench. See chapter "Dimensions" for wrench size. Warning: The housing or the electrical connection may not be used for screw- ing in! Tightening can cause damage, e. g. to the rotation mechanism of the housing.

  • Page 13: Mounting Instructions

    Mounting instructions Installation position Mount NivoGuide 8100 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 NivoGuide® 8100 • Two-wire 4 … 20 mA/HART 4 Mounting Fig. 5: Mounting in non-metallic vessel Flange Metal sheet 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. Higher sockets or sockets with a bigger diameter can generally be used.

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.
  • Page 16 NivoGuide® 8100 • Two-wire 4 … 20 mA/HART 4 Mounting Pressure The process fitting must be sealed if there is gauge or low pressure in the vessel. Before use, check if the seal material is resistant against the measured product and the process temperature. The max. permissible pressure is specified in chapter "Technical data" or on the type label of the sensor.
