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. The position of the
tuning fork is marked by a marking on the hexagon of
OPTISWITCH 4000 C. 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 adhesive and viscous products, the surfaces of the tuning
fork should protrude into the vessel to avoid buildup. Therefore
sockets for flanges and mountings bosses should not exceed
a certain length.
