1 Marking
In case of horizontal mounting in adhesive and viscous products,
the surfaces of the tuning fork should be vertical in order to reduce
buildup on the tuning fork. On the screwed version you will find a
marking on the hexagon. With this you can check the position of the
tuning fork when screwing it in. When the hexagon touches the seal,
the thread can still be turned by approx. half a turn. This is sufficient to
reach the recommended installation position.
In the case of flange versions, the fork is aligned with the flange holes.
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, un-
wanted false measurement signals can be generated. For this reason,
mount OPTISWITCH 5100 C, 5150 C at a position in the vessel where
no disturbances, e.g. from filling openings, agitators, etc., can occur.
To make sure the tuning fork of OPTISWITCH 5100 C, 5150 C gener-
ates as little resistance as possible to product flow, mount the sensor
so that the surfaces are parallel to the product movement.
The second seal of the gas-tight leadthrough (option) prevents an
uncontrolled leakage of the medium. The service life of the gas-tight
leadthrough depends on the chemical resistance of the materials.
See " Technical data ".
Caution:
If it is determined (e.g. via an error message from OPTISWITCH 5100
C, 5150 C) that medium has already penetrated into the vibrating ele-
ment, the instrument must be exchanged immediately.
