Warning:

The housing must not be used to screw the instrument in!

Applying tightening force on the housing can damage its

internal mechanical parts.

To screw in, use the hexagon above the thread.

4.2 Mounting information

The vibrating element should protrude into the vessel to avoid

buildup. For that reason, avoid using mounting bosses for

ﬂanges and screwed ﬁttings. This applies particularly to use

with adhesive products.

Install the instrument in such a way that the tuning fork does

not protrude directly into the ﬁlling stream. S hould such an

installation location be necessary, mount a suitable baﬄe

above or in front of the tuning fork.

If such an installation location should be necessary, mount a

suitable protective sheet above or in front of the vibrating

element - see illustration a.).

In abrasive solids, mounting acc. to illustration b. has proven. A

spout forms in the concave protective sheet preventing wear of

the protective sheet.

To achieve a very precise switching point, you can install

OPTISWITCH 3100 C horizontally. However, if the switching

point can have a tolerance of a few centimeters, we

recommend mounting OPTISWITCH 3100 C approx. 20°

inclined to the vessel bottom to avoid buildup.
