To minimise ﬂow resistance caused by the tuning fork, LEVEL

SWITCH 8112 should be mounted in such a way that the surfaces of

the blades are parallel to the product movement.

Due to the eﬀects of agitators, equipment vibration or similar, the level

switch can be subjected to strong lateral forces. For this reason, do not

use an overly long extension tube for LEVEL SWITCH 8112, but check

if you can mount a level switch on the side of the vessel in horizontal

position.

Extreme vibration caused by the process or the equipment, e.g.

agitators or turbulence in the vessel, can cause the extension tube of

LEVEL SWITCH 8112 to vibrate in resonance. This leads to increased

stress on the upper weld joint. Should a longer tube version be

necessary, you can provide a suitable support directly above the

tuning fork to sec ure the extension tube.

This measure applies mainly to applications in Ex areas category 1G or

WHG. Make sure that the tube is not subject to bending stress due to

this measure.
