Sensor with liquid KCl electrolyte
!
Note!
In case of symmetrical pH measurement, you must push the PML connector onto the PML
connection (PML = potential matching line, pos. 2). Please, read the Operating Instructions of the
transmitter.
1. Remove the splash protection cap (Fig. 16,
pos. 6) and the KCl hood (pos. 7) incl. the
protective tube from the assembly.
2. Then slacken the retractable pipe (pos. 3) by
turning it counterclockwise.
3. Screw in the sensor:
a. Unscrew the tension sleeve (pos. 12)
from the inner pipe (pos. 11) and pull the
inner pipe out of the retractable pipe.
b. Install the sensor (pos. 10) into the inner
pipe:
– first screw by hand
– then tighten the sensor by
approx. ¼ turn using an open end
wrench (AF 17).
c. Push the inner pipe with the sensor into
the retractable pipe and screw the
tension sleeve to the inner pipe.
4. Screw the retractable pipe with the sensor
onto the assembly (clockwise, by hand).
5. Insert the measuring cable through the
protective tube and the KCl hood (pos. 7):
– Fixed cable:
from the sensor upwards to the
transmitter
– Sensor with plug-in head:
from the top through the KCl hood to the
sensor
6.
Plug-in head sensor only:
Connect sensor and cable.
7. Connect the electrolyte supply tube (pos. 1)
to the electrolyte connection of the sensor.
8. Affix the supplied tubing support (pos. 9) to
the electrolyte supply tube directly above the
electrolyte connection.
9. Attach the KCl hood to the retractable pipe.
Guide the electrolyte supply tube through
the lateral slot of the hood.
10. Place the measuring cable in the splash
protection cap and place the cap on the
protective tube of the KCl hood.
Remove the sensor in the reverse sequence of
operations.
