Since pH/ORP/pION sensor cables generally
contain a low-noise conductive layer within
the coax, complete removal of this layer is
extremely important to ensure correct sensor
operation. Additionally, most conductors
within the sensor cable are small and are not
recommended to be used directly in the TB84PH
Advantage Series’ terminal blocks; therefore,
the BNC Adapter (p/n 4TB9515-0164 or 4TB9515-
0166) is recommended over removing the BNC and
stripping back each of the individual
conductors.
Using Figure 3-8 as a reference, install the
BNC Adapter and connect the BNC-type sensor as
follows:
1) Remove the earth ground screw and hardware
located below the SENSOR CONNECTIONS terminal
block.
2) Slide the earth ground screw (and remaining
hardware if desired) through the screw hole on
the BNC Adapter so that the adapter’s leads
and female BNC are pointing upwards.
3) Mount the BNC Adapter to the available
threaded earth ground hole.
