– The metal body of the turbidity sensors as well as the safety weld-in
sockets METTLER TOLEDO housing InFit Typ 76*-*** and InTrac 7**-***
are, if necessary, to be included into the recurring pressure test of the unit.
– The turbidity sensors may only be operated in conjunction with the
transmitter Trb 8300.

Initial start-up

Handling

The fiber optic cables have a core of Hard Clad Silica (HCS) fibers. When
laying fiber optic cables, the bend radius must always exceed at least
10 cm (4"). Fiberoptic cables may never be shortened independently.
Fitting of the SMA plug requires special tooling. The transparent plastic cap
on the sensor is to be removed before use. Any formation of deposits of
solid particles on the surface is to be avoided. Gas bubbles in the process
medium are also able to produce a signal and are therefore to be avoided
wherever possible. If this is not viable, please refer to the instruction
manual of the METTLER TOLEDO Transmitters Trb 8300 (chapter:
«Calibration»).

Installation in vessels/reactors

The turbidity sensors are to be installed at a distance of at least 10 cm (4")
from the walls of the vessel, agitator and other internals, in order to prevent
disturbances through reflections. When employing special METTLER
TOLEDO retractable housings InTrac with modified immersion tubes, the
installation guideline valid for each individual housing is to be observed.
This step likewise, is to avoid measurement disturbances arising from
irrelevant light reflections (see chapter 7.2: «Accessories/Housings»).
