Introduction
Thank you for choosing the Sensorex CS665 Steam-Sterilizable 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), Standard
Four-Wire Cable” under Cable Length would be BC, “Tinned Leads” under Cable Termination Connector would be 3, “Sensorex-Branded” under
Branding would be A, and “1.5” NPT Stainless Steel“ under Installation/Fitting Type would be 7. The order code would then be “CS665 – B – 1 – BC –
3 – A – 7”.

Calibration
Calibrate sensor according to meter/controller manufacturer’s
instructions using known certified conductivity standards. Be
sure and calibrate in large beaker or bucket, stirring sample with
electrode. Avoid bubbles as much as possible; bubbles cause
erroneous readings.

Sensor Installation
Mechanical
1. Mount electrodes in stainless steel sanitary tee (1.5” or
2”, depending on selected options). See FIG 1. Place seal
provided with tee in groove on tee flange as shown.
2. Seat electrode on top of seal so that seal’s raised edge sits
in groove on the underside of flange. See FIG 1. Attach clamp
around tee flange and electrode flange. Swing wing nut into slot
in flange and tighten clockwise to seal.
3. Align sensor hole as closely as possible with center of tee
outlet. See FIG 2.
Always shut off flow when installing or removing
electrodes.
Electrical
Follow conductivity meter/controller manufacturer’s instructions.
Please note the following sensor wiring configurations:
WhiteWhite: Conductivity (Outer Electrode)
Black: Conductivity (Inner Electrode)
Green and Red: Temperature Sensor
ClearClear: Shield
Follow wiring instructions supplied with your controller.
Sensor Cleaning
Do NOT clean sensors with an abrasive brush that
could scratch the surface of the stainless steel. This will
adversely affect the measurement.
