3-6. Adjusting the insertion
depth
The insertion depth of the electrode
can be adjusted to your preference
(see fig. 3-6). An insertion depth of
at least 0.2 m is recommended for
a fast response of the temperature
sensor. This sensor is located
above the combined electrode.
When the probe is inserted for 0.2
m or more the temperature sensor
will follow the process temperature
accurate.
The 'memory'ring can be positio-
ned at the actual insertion position
of the probe. The "Allan"key, sup-
plied with the fitting is used to fix
the 'memory'ring at the desired
fig. 3-6 variable insertion depht
position. The maximum insertion
depth is related to the probe length
mentioned in the model code of the
fitting.
3-7. Wiring
The cable used in the PR20
retractable fitting is prepared for
easy connection to pH transmitters.
The numbering of the wires is
accordingly to the standard numbe-
ring of Yokogawa transmitters.
Remark:
To make full use of the capabilities
of the combined pH/Reference
electrode, the cooperation with
Yokogawa pH transmitters is
preferred.
