3. INSTALLATION OF DO72
Using sensor adapters the DO72 optical
dissolved oxygen sensor can be assem-
bled into any Yokogawa flow or immer
-
sion/floating fitting, like: FF20, FF40 flow
fitting, the PB350G angled floating ball
holder, PB360G vertical floating ball hold
-
er, or DOX8HS submersion type holder.
Fitting assembly asures sensor to be sub-
merged to the optimum point to obtain
precise measurements.
The DO72 can be also mounted to
process and existing fitting product line
using standard adapters.
3.1 Installation in sensor holder
An adaptor (optional Fig. 4) is necessary
to assemble DO72 into the DOX8HS sub-
mersion type holder (see Fig. 1), PB350G
angled floating ball holder (see Fig. 2), or
PB360G vertical floating ball holder (see
Fig. 3).
For mounting the sensor into the FF20
and FF40 flow fitting use sensor adapter
as described in figure 5,6 and 7.
3.1 Preparing the sensor for use
Make sure that the Oxygen Exchange
Cap (OEC) is screwed tightly to the probe
body and did not work loose while han-
dling the probe.
3.2 Mounting the sensor
Choose a holder / fitting that suits the
liquid to be measured and the measure-
ment location.
Note:
Avoid choosing a location where
the solution is unevenly distributed,
since heavy hunting may result in the
measured value. Also, avoid locations
where bubbles occur frequently.
Note that, if a measured solution run-
ning at a high flow rate contains particles
of sand, the permeable membrane of the
sensor may be damaged.
