Introduction
Thank you for choosing the Sensorex CS300 Process Graphite Contacting Conductivity Sensor. See below for ordering
configurations and product specifications.
For example, choosing “0.1/cm” under Cell Constant would be B, “PT1000 RTD” for Temperature Compensation would be 1, “10 feet (3m) S856”
under Cable Length would be FC, “Tinned Leads” under Cable Termination Connector would be 3, and “Sensorex-Branded” under Branding would
be A. The order code would then be “CS300 – B – 1 – FC – 3 – A”.

Calibration
Follow calibration instructions in your conductivity transmitter or
controller manual. Suggested calibration is at least two 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 Installation
Mechanical
1. Glue (FC875/S) or thread (FC875/T) into your cooling
tower water loop.
2.Install sensor into the tee by aligning the notch of the sensor
with the FC875 tab. See FIG 1.
3.Slide nut of FC875 tee over sensor and tighten. See FIG 2.
4.Attach cable to top of sensor by aligning the black tab of the
sensor with the slot of the cable. Press in and then tighten nut.
See FIG 3.
Electrical
Follow conductivity meter/controller manufacturer’s instructions.
Please note the following sensor wiring configurations:
Center of Coaxial: Conductivity
Braid of Coaxial: Conductivity
Red: Temperature Sensor
Black: Temperature Sensor
Green: No Connection
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.
