SECTION 3 - SENSOR/INTERCONNECT CABLE DETAILS

3.1Sensor Cable Details

The sensor’ 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.

3.2Interconnect 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.

OMEGA strongly recommends ising only its CDE3600-CAB interconnect cable. If a different cable is used, it must have equivalent construction: four conductors, and two separate isolated shields -oneshielding 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’ ability to properly measure.

i

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

!4 inch of the outer cable jacket and outer

shield foil.

Be careful not to damage the exposed section of the cellophane binder.
