instrument configuration or calibration, ensures the highest possible
measurement accuracy

??

Built with a Pt 1000 RTD temperature element located at its tip to provide

These sensors are for use with the CDCN684, CDCN685, CDCN686 Analyzers

and CDTX680 Series transmitters only.
Sensor Characteristics
Basic Cell Constant:
Installation Style: For sensors with a 0.05 cell constant, use K-inch or %-inch male

NPT compression fittings made of Kynar (PVDF) or 316 stainless steel. For
sensors with any other cell constant, use a %-inch male NPT compression fitting
made of Kynar or 316 stainless steel. In all cases, the fitting enables the sensor to
be insertion mounted, up to 4 inches/ 102 mm deep, into a pipe tee or vessel.
Reversing the fitting enables the sensor to be fastened onto the end of a pipe for
immersion mounting.

The

compression fitting style sensor may be insertion mounted
into a pipe tee or vessel fitting. By reversing the compression fitting, the sensor
can be fastened to the end of an appropriate length pipe for immersion
mounting. The “longer version” compression style sensor is intended to be
mounted into a ball valve assembly, enabling sensor removal without stopping
the process flow. Figure 2-l shows the sensor ’s general dimensions.

General Dimensions and Cable Wire Details

To ensure optimum measurement performance, follow these guidelines when
insertion mounting the sensor:

??

Install the sensor into the pipe run so that the process flows directly into the

end of the sensor (see Figure 2-2).

??

Preferably, mount the sensor in a vertical position to eliminate the possibility
of trapped air bubbles from contacting its electrodes which can cause
measurement error. This also prevents loose pipe line sediment from
accumulating and obstructing the sensor electrodes.

After tightening the compression nut, the ferrule will be
permanently crimped. Therefore, make sure that the sensor is

inserted to the proper depth before tightening the compression
nut.

C. With the

sensor properly positioned, tighten the compression nut onto the
compression fitting to crimp the ferrule. Use one wrench to hold the fitting
and another to turn the nut 1 to 1% turns. This should provide an effective
process seal. Also, the crimped ferrule becomes a convenient reference
indicator for insertion depth when re-inserting the sensor after cleaning.

This completes the insertion mounting

Installation Tip!

Re-using Compression Fitting, Nut, and Crimped Ferrule:
If the sensor is re-installed, the compression fitting and nut can be re-used. The

crimped ferrule, however, may need to be cut away from the sensor to remove it,
making it unusable. If you can remove the crimped ferrule without destroying it,
and if it can still provide an effective process seal, you can probably re-use it at
least the number of times listed below:

Immersion Mounting

1. Reverse the compression fitting assembly on the sensor so that the longer
threaded section faces towards the sensor cable end (see Figure 2-4).

2. Position the compression fitting assembly at the far cable end of the sensor

body and tighten the compression nut onto the compression fitting. Use one

wrench to hold the fitting and another to turn the nut 1 to 1% turns to crimp
the ferrule. This provides a process seal.

Sensor Cable Details

The sensor’s integral cable is a 6-wire crosslinked polyethylene-jacketed cable
with 4 conductors and two isolated shield wires. Refer to Figure 2-l for the
function and color of each wire in the sensor ’s integral cable.

Interconnect Cable Details

The OMEGA interconnect cable

CDE3600-CAB

is provided with unfinished
ends since it must often be shortened during installation. The cable is very
similar to the sensor’s integral cable except that it has two additional conductors
(green and yellow) which are not required. When stripping the interconnect
cable during termination, purposely cut off these green and yellow wires from
each end of the stripped-back cable. This ensures the same wire color coding
used by the sensor’s integral cable.

only its

OMEGA strongly recommends
interconnect cable. If a different cable is used, it must have
equivalent construction: four conductors, and two separate
isolated shields

the measurement signal from electromagnetic interference.
Using a cable with different construction may interfere with
the measurement system’s ability to properly measure.

SERVICE AND MAINTENANCE

RECOMMENDED CLEANING PROCEDURE

Keep the sensor reasonably clean to maintain measurement accuracy. The time
between cleanings (days, weeks, etc.) is affected by the characteristics of the
process solution and can only be determined by operating experience.

1.

Remove most contaminate buildup by carefully wiping the inner electrode
rod, and the concentric outer electrode tube (inner and outer surfaces) with a
soft clean cloth. Then rinse the sensor with clean, warm water.

Prepare a mild soap solution. Use warm water and dishwashing detergent,

2.

Borax hand soap, or a similar soap.

3.

Soak the sensor for 2 to 3 minutes in the soap solution.

4.

Use a small bristle brush, cotton swab (Q-tip), or pipe cleaner to scrub the
entire measuring end of the sensor, thoroughly cleaning the electrode surfaces.
If detergent solution cleaning cannot remove surface deposits, use muriatic
acid (or another dilute acid) to dissolve the deposits. The acid should be as
dilute as possible, but yet strong enough to clean. Experience will help
determine which acid to use and how dilute it can be. Some stubborn coatings
may require a different cleaning agent. For assistance in these difficult cases,
contact the OMEGA Service Department (see page 12).

Before cleaning with acid, determine if any hazardous reaction products could
form. (Example: A sensor used in a cyanide bath should not be put directly
into a strong acid for cleaning because poisonous cyanide gas could be
produced.) Acids are hazardous. Wear appropriate eye protection and clothing
in accordance with Material Safety Data Sheet recommendations.

Soak the sensor in dilute acid for no more
with clean, warm water and then place the sensor back into the mild soap
solution for 2 to 3 minutes to neutralize any remaining acid.

Rinse the sensor in clean, warm water.

Checking Sensor Operation

Use the troubleshooting section in the analyzer instruction manual to determine
whether the sensor or analyzer is in-operative. If you suspect the sensor, check it
using this procedure:

1. Disconnect the sensor from the analyzer (or junction box, if using interconnect
cable).

2. Clean the sensor using the procedure in Part Three, Section 1.

3. Using an ohmmeter, check all of the measurement point resistance readings
shown in Table A below.

Be sure that the ohmmeter is set to its highest range for all
infinite (open circuit) resistance readings shown in Table A.

If you cannot get the required readings for one or more of the resistance

checks in step 3, the sensor is probably inoperative. Refer to OMEGA ’s
warranty/replacement plan for sensor replacement details. If all resistance

checks are okay, the sensor may still be inoperative. In this case, more
extensive troubleshooting is required. Please consult the OMEGA Customer
Service Department for details (see page 12).
