2.3.3 Connecting Conductivity Probe
Any industrial conductivity probe (2-cell or 4-cell) can be connected to the
conductivity monitor.
2-Cell Conductivity Probe:
1. Short Pin 1 & 2 of J10 connector using a jumper wire.
2. Connect CON low input wire (white) to Pin 2 of J10 connector.
3. Connect CON high input wire (black) to Pin 3 of J10 connector.
4. Short Pin 3 & 4 of J10 connector using a jumper wire.
4-Cell Conductivity Probe:
1. Connect CON low input wire (black) to Pin 1 of J10 connector
2. Connect CON low input wire (white) to Pin 2 of J10 connector.
3. Connect CON high input wire (orange) to Pin 3 of J10 connector.
4. Connect CON high input wire (blue) to Pin 4 of J10 connector.
2.3.4 Connecting Temperature Probe
For Automatic Temperature Compensated (ATC) conductivity readings, an
in-built temperature sensor is usually integrated with industrial conductivity
probes. Alternatively, a separate 100
Ω Pt RTD temperature probe (2-wire or
3-wire) can be connected to the monitor.
3-Wire Probe:
1. Connect PT100 compensate wire to Pin 5 of J10 connector.
2. Connect PT100 sense wire to Pin 6 of J10 connector.
3. Connect PT100 GND wire to Pin 7 of J10 connector.
2-Wire Probe:
1. Short Pin 5 & 6 of J10 connector using a jumper wire.
2. Connect PT100 sense wire to Pin 6 of J10 connector
3. Connect PT100 GND wire to Pin 7 of J10 connector.
