Mounting
General Safety Instructions
Process pressure
Improper installation may result in loss of process pressure.
Chemical resistance
against the medium
Materials of construction are chosen based on their chemical compatibility (or inertness) for general purposes.
For exposure to specific environments, check with chemical compatibility charts before installing.
Mounting location
The right mounting place is significant for a proper function. Observe mounting instructions.
Vibrations
Avoid mounting in applications with strong vibration. Use rubber mounts for absorption in case of light
vibrations.
Mounting instructions
Mounting position
• The unit is mounted vertically on the silo. Max. deviation is 2°.
• There must be at least 200mm (7.87“) space for the sensor weight to move down in case of a full silo.
Observe the bottom of the sensor weight at "upper stop position" (dimensions see page G4 - G6).
Additional Safety Instructions for Hazardous Locations
Installation regulations
For devices to be used in Hazardous Locations the respective valid installation regulations must be observed.
Sparks
The installation has to be done in a way, that mechanical friction or impact does not cause sparks between
the aluminium enclosure and steel.
• The socket pipe of the unit must
protude at least 50mm (2") into
the silo. A version with longer
socket pipe is available.
• Proper movement of the sensor weight must be
guaranteed, even if the sensor weight oscillates.
Observe enough distance to the silo wall, stanchions
and built-in fittings.
