KROHNE OPTISWITCH 5100C Relay EN - Manual (Page 14)

When used in adhesive and viscous products, the tuning fork
should protrude into the vessel to avoid buildup. For that
reason, sockets for flanges and mounting bosses should be
avoided when mounting horizontally.
If OPTISWITCH 5100 C, 5150 C is mounted in the filling
stream, unwanted switching signals may be generated. Mount
OPTISWITCH 5100 C, 5150 C at a location in the vessel
where no disturbing influence from e.g. filling openings,
agitators etc. can occur.
To minimise flow resistance caused by the tuning fork,
OPTISWITCH 5100 C, 5150 C should be mounted in such a
way that the surfaces of the blades are parallel to the product
movement.
Instruments with enamel coating should be treated very
carefully and shocks should be avoided. Unpack OPTI-
SWITCH 5100 C, 5150 C directly before installation. Insert
OPTISWITCH 5100 C, 5150 C carefully into the vessel
opening and avoid touching any sharp vessel parts.
