1. Description
•
•
•
•
CDTX-285X Series Conductivity/Resistivity Sensor Electronics provides either a two-wire 4 to 20 mA output.
The 4 to 20 mA output models provide eight ranges for each electrode cell constant, plus the ability to invert each range.
The EasyCal feature allows the devices to automatically recognize standard conductivity test solution values for simple field calibration.
The Conductivity sensor provided with integral systems will have its custom cell constant information programmed into the electronics
at the factory to provide a 2% sensor accuracy. See Section 8 for details.

6. In-Line Installation
Most of the Conductivity/Resistivity electrodes used with the CDTX-285X
can be installed into standard 3/4 in. (NPT or ISO 7-R3/4) fittings.
The CDTX-285X models are designed for integral systems,
where the electronics are attached directly to the sensor.
The preferred installation for in-line applications directs flow
straight into the electrode. This configuration reduces the
probability of entrapped air bubbles, and provides the best
continuous sampling of the fluid content.
If the electrode is mounted vertically in a tee, do not recess the
electrode orifices inside the tee. Mounting upside down may help
prevent air entrapment.
An oversized tee or flow cell may be helpful for inline installations.
At least 4 threads (ANSI B1.20.1) must be engaged to meet the
pressure rating as published in the specifications.
Use the CDTX-285X-RM models for in-line installations
where the electronics must be separated from the electrode.
Conductivity electrodes with sanitary flange fittings must be
installed using this option.
7. Submersible Installation
While the CDTX-285X and CDTX-2850-RM
electronics cannot be submerged, either model
will accommodate tank installation.
Select any electrode with a 5 m (15 ft.) cable.
The cable may be cut to length,
but it CANNOT BE EXTENDED.
The universal adapter included with
CDTX-285X-RM models can be attached to the
top of a tank or mounted to a surface near the tank.
Adapt the CDTX-285X models to tank installations
by attaching a clamp to the conduit.

The CDE-285X Conductivity sensors come with a certificate of calibration. This certificate provides information regarding the actual
cell constant and temperature offset as tested and verified according to NIST standards. This information has been programmed into
the CDTX-285X electronics as its default factory value. If required, the sensor can be recertified by contacting Omega.

12. EasyCal
EasyCal is a single-point calibration system. During this procedure, if the measured value is within ±10% of any of the test values
listed below, the CDE-285X will automatically recognize the test value and calibrate the output to that value.
Note:
The first step (Reset) is recommended each time an electrode is replaced, but is NOT necessary upon initial installation or periodic
calibration.
1.
Reset the CDE-285X to factory calibration: Set all switches on SW3 (and SW4 for dual input) to OPEN. Apply power, wait at
least 3 seconds, then press and hold SW1 until the LED (D3) comes on steady then goes off again (approx. 10 seconds).
When the LED goes off, release SW1; reset is complete. Reset SW3 and SW4 to the proper settings.
2.
Place the electrode/sensor assembly into the conductivity test solution appropriate to your operating range.
Shake the electrode to dislodge any air bubbles visible on the surface of the electrode.
• 146.93 μS, 1408.8 μS, 12856 μS (per ASTM D1125-95)
• 10 μS, 100 μS, 200 μS, 500 μS, 1000 μS, 5000 μS, 10,000 μS, 50,000 μS, 100,000 μS.
• Allow at least 2 minutes for the electrode response to stabilize.
3.
Press and hold SW1 for approximately 8 to 10 seconds. During this time, the LED will come on steady then go back off. (If the
LED blinks several times rapidly, the calibration was not successful. See the troubleshooting section).
Calibration is complete. Return the system to service.

13. Maintenance
• The CDTX-285X requires no periodic maintenance.
• Coatings on the electrode may cause slow response or drift.
• Clean metallic surfaces with a mild detergent and a non-abrasive brush or cotton swab.
14. Troubleshooting
LED and Output Condition
Possible Causes
Suggested Solutions
Current Out:
LED off, current output is 22 mA
• SW3 and SW4 set to all OPEN

• No electrode installed
• SW3 (and SW4) not set correctly
• System not ready

•
•
•
During EasyCal, the LED blinks rapidly
for 4 seconds
• Measured value of the test solution is
outside the ±10% tolerance
• The electronics or the electrode is
defective
• Use fresh test solutions and restart the
calibration
• Replace the electronics or the electrode
After completing calibration procedure,
the output values are inaccurate
• Insufficient time allowed for electrode
• Recalibrate and wait at least 2 minutes

measurement (or vice versa)
The output of the CDTX-285X indicates
a value that is off by a factor of 10
(e.g. 10x, 100x the correct value)
• The cell constant selection on the
CDTX-285X (SW3 or SW4) does not
match the actual input

Normal for new system
Install electrode
Set SW3 and SW4 correctly
Retry (recycle power)
• Match the CDTX-285X switch settings
