PRODUCT INSTRUCTION SHEET
CS8000TC - Cooling Tower Conductivity Sensor
and Flow Cell Installation
Introduction
Your CS8000TC conductivity sensor system installs easily by
following the steps below:
1) Glue (FC875/S)or thread (FC875/T) into your cooling tower
water loop.
2) Install CS8000TC into the tee by aligning the notch of the
CS800TC with the FC875 tab as shown in FIG 1.
3) Slide nut of FC875 tee over CS8000TC and tighten as
shown in FIG 2.
4) Attach S855 cable to the top of CS8000TC sensor by aligning the black tab of the CS8000TC sensor with the slot of the
S855 cable. Press in and then tighten nut as shown in FIG3.
Electrical Connections
Follow wiring connections from your conductivity transmitter
of controller.
Wiring from S855 Cable is as follows:
Wire Color Function
Red Conductivity
Black Conductivity
Green Temperature
White Temperature
Calibration
Follow calibration instructions in your conductivity transmitter
or controller manual. Suggested calibration is at least 2 points.
One point is in air (0uS) and the other is typically >75% of the
selected range. See www.sensorex.com for a wide range of
conductivity standard solutions.

Sensor Repair
Do not attempt to repair any part of the sensor. If the sensor's
cable is damaged, consult the factory for details.
Sensor Storage
If long-term storage of probes is required, rinse off the sensor
in clean water and dry off completely before storing.
