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.
Termination Style: An integral 6 m (20 ft.) long cable
Operating Procedures
Always consider the temperature/pressure ratings of the mounting hardware
used to install the sensor. The sensor and hardware combination is an integrated
system. The hardware material usually limits the system ’s temperature/pressure
rating. Refer to Section 2 for complete specifications.

Insertion Mounting
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.

CDE681-series 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.

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.

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.

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:

- one shielding the signal, and one shielding
the overall cable. These specific cable characteristics protect
the measurement signal from electromagnetic interference.
Using a cable with different construction may interfere with
the measurement system’s ability to properly measure.
To correctly terminate the ends of the interconnect cable, refer to Figure 2-6 and
follow this procedure:
Carefully strip back 2% inches of the outer cable jacket, the outer shield foil,
and the cellophane binder. This exposes the sensor shield wire, the inner
shield wire, and the three foil-wrapped wire pairs.
Cut off the exposed 2% inches of only the yellow and green wire pair.
Peel back and cut off the exposed inner shield foil from the red/black and
blue/white wire pairs.
Carefully strip back an additional
CDE3600-CAB
interconnect cable. If a different cable is used, it must have
equivalent construction: four conductors, and two separate
isolated shields
ising
only its
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.

- 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.
2.
3.
4.
5.
6.
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,
Borax hand soap, or a similar soap.
Soak the sensor for 2 to 3 minutes in the soap solution.
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
than 5 minutes. Rinse the sensor
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.
Calibrate the analyzer using the procedure in the analyzer instruction manual.
If calibration cannot be attained, check the sensor using the procedure in Part
Three, Section
2.1.

4. 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

2.1 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
