WIRING
3.3 SENSOR WIRING
Keep sensor wiring separate from power wiring. For best EMI/RFI protection, use shielded output signal cable in an
earth-grounded metal conduit. See Figure 3-4. Refer to the Instruction Sheet provided with each sensor for specific
wiring instructions.
3.1.1 WIRING THROUGH A JUNCTION BOX
The sensor can be wired to the analyzer through a remote junction box (PN 23550-00). Wire the extension cable and sen-
sor cable point-to-point. See Figure 3-4. Refer to the sensor instruction manual for more details.
Factory-terminated (PN 23294-05) and unterminated (PN 9200276) connecting cable are available. The use of factory-ter-
minated cable is strongly recommended. To prepare unterminated cable for use, follow the instructions in the sensor
instruction manual.
For maximum EMI/RFI protection, the outer braid of the sensor cable should be connected to the outer braided shield of
the extension cable. At the instrument, connect the outer braid of the extension cable to earth ground.
3.1.2 SENSOR SELECTION
All Rosemount Analytical contacting conductivity sensors with PT100 RTD or PT1000 RTD are compatible with the Model
Xmt-C transmitter. Refer to the Instruction Sheet provided with each sensor for specific wiring instructions.
Choose a contacting conductivity sensor that is appropriate for your process conditions and range of conductivity meas-
urement.
