Section 3 - Location Requirements
Locate the sensor as close as possible to the instrument. Depending on the instrument model
and full-scale range, the maximum allowable distance between sensor and instrument varies
(refer to instrument manual for distances).
NOTE: When indirectly wiring the sensor to the instrument with interconnect cable and a
junction box, use only an Anderson specified cable. When using a different cable, it
must have equivalent construction: five conductors and two separate isolated shields
— 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 measuring system’s
performance.

Section 4 - Sanitary MountingSection 4 - Sanitary Mounting
Section 4 - Sanitary Mounting
The sanitary style sensor may be clamp-mounted for clean-in-place applications by using a
sanitary clamp-type tee or ferrule and clamp.
1. Install a 2-inch sanitary clamp-type tee or ferrule into the process line or vessel.
NOTE: For a 2" line a special 2" x 2" tee is available from Anderson. Use of a 2" x 2"
standard, or short-outlet tee will introduce calibration errors. Alternatively, the
sensor may be mounted in a 2 1/2" x 2", or 3' x 2' short-outlet reducing tee.
2. Connect the sensor cable wires to the instrument.
• Direct Connection
A) Route sensor cable into the instrument through a watertight fitting in a cable entry
hole.
B) Connect sensor wires to the instrument. Refer to the instrument operating manual
for details.
•Indirect Connection with Junction Box (see Section 5.4 for details)
C) Mount a junction box that has a terminal strip onto a flat surface. Make sure the
junction box cover can be removed after installation.
3. Before installing the sensor into the process line or vessel, calibrate the measuring
system with conductivity reference solution using the procedure in the instrument
operating manual.
4. After calibration, mount the sensor into the sanitary tee or ferrule:
A. Properly seat the sanitary gasket onto the mating surface of the tee or ferrule.
B. Carefully place the sensor into the tee or ferrule, making sure the gasket is in
place and contacting the bottom surface of the integral sensor flange.
C. Rotate the HC1 sensor in th process line so that the arrow on the sensor housing
is aligned with the direction of product flow.
NOTE: If the sensor is not properly aligned with the product flow, calibration errors may
result.
D. Secure the sensor onto the tee or ferrule with a clamp.
NOTE: If the sensor is installed in a temperature cycling process, the wing nut may need to
be periodically re-tightened.
CAUTION:
STEAM STERILIZATION IS NOT RECOMMENDED FOR CLEANING THE
HC1 SANITARY STYLE ELECTRODELESS CONDUCTIVITY SENSOR.

CAUTION:
IF THE SENSOR OR INTERCONNECT CABLE IS NOT TERMINATED
EXACTLY AS DESCRIBED IN THIS SECTION, THE MEASURING SYSTEM
WILL NOT OPERATE PROPERLY.
5.1 SENSOR CABLE DETAILS
Depending on how the sensor was ordered, its integral cable is terminated one of two ways:
•Standard Termination: For all applications except those using instruments with the
European Community “CE” label. The sensor cable is terminated with five colored
wires (red, green, yellow, white, and blue) and one shield wire (signal shield wire and
cable shield wire are electrically common).
•CE Termination: Available by special order for applications using instruments with
the European Community “CE” label. The sensor cable is terminated with five colored
wires (red, green, yellow, white, and blue), and two separate isolated shield wires
(signal shield wire and cable shield wire is electrically isolated).
In either case, the integral sensor cable may require shortening during installation. When
doing this, refer to the appropriate subsection (5.2 or 5.3) for the procedure to re-terminate the
sensor cable.

1. Refer to Figure 5-1 and strip back 3 inches (76 mm) of the outer cable jacket, outer foil
wrap, cellophane wrap, inner foil wrap, and unused black wire. This exposes the signal
shield wire, the cable shield wire, and five colored wire (red, green, yellow, white, and
blue).
2. Twist the signal shield wire and cable shield wire together, and insulate the new
combined shield wire with shrink wrap or tape.
3. Strip the insulation back 1/8 inch (3 mm) from each of the colored wires. Then tin each
stripped wire.
4. Using shrink wrap or tape, secure the terminated bundle (outer cable jacket, five
colored wires and combined shield wire). This completes the standard termination.

LABEL. IF THE INSTRUMENT IS NOT "CE CERTIFIED," USE THE
STANDARD TERMINATION PROCEDURE DESCRIBED IN SECTION 5.2
1. Refer to Figure 5-2 and carefully strip back an appropriate length of the outer cable
jacket and outer foil wrap. This exposes the signal shield wire, cable shield wire, and
cellophane-wrapped wire bundle.
2. Fold back the cable shield wire. Using shrink wrap or tape, equally cover the outer
cable jacket, and the exposed cable shield wire/cellophane-wrapped wire bundle.
3. Carefully clip back the cellophane wrap, inner foil wrap, and unused black wire up to
the end of the shrink wrap or tape applied in step 2. This exposes the signal shield
wire, and the five colored wires (red, green, yellow, white, and blue).
4. Insulate the signal shield wire with shrink wrap or tape.
5. Strip the insulation back 1/8 inch (3 mm) from each of the colored wires. Then tin each
stripped wire.
6. Using an ohmmeter or test light, verify that the signal shield wire is not shorted to the
cable shield wire. If okay, shorten the cable shield wire to an appropriate length. If not,
clip entire cable back to get a new unfinished end and start over at step 1.
7. Using shrink wrap or tape, equally overlap the existing shrink wrap or tape applied in
step 2, and the five colored wires/signal shield wire. This secures and completes the
terminated assembly.

5.4 INTERCONNECT CABLE DETAILS5.4 INTERCONNECT CABLE DETAILS
5.4 INTERCONNECT CABLE DETAILS
The Anderson specified interconnect cable, which is the same cable as the integral sensor
cable, is provided with unfinished ends since it often needs to be shortened during installation.
Use the appropriate procedure in subsection 5.3 or 5.4 to terminate either cable.
NOTE: Anderson Instrument Company strongly recommends using only its specified
interconnect cable. If a different cable is used, it must have equivalent construction:
five conductors, and two separate isolated shields — 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 measuring system’s ability to operate properly.
If the application requires interconnect beyond the standard 20' length the use of a
Interconnect Cable / Junction box is required to ensure a quality connection.
1. Mount the junction box on a flat surface, within 20' of the electrodless conductivity
sensor.
2. Route the sensor and interconnect cable ends through the provided cord grips.
3. Prepare the ends of the cable as described in Section 5.3 keeping the two shield
wires insulated from each other with shrink wrap or tape.
4. Terminate the wires to the appropriate terminals according to wire color.
5. Replace the junction box gasket and cover and tighten the cord grips to prevent
moisture ingression.

6.1 CHECKING SENSOR OPERATION6.1 CHECKING SENSOR OPERATION
6.1 CHECKING SENSOR OPERATION
Determine whether the sensor or instrument is defective by using the troubleshooting section in
the instrument operating manual. If the sensor is suspect, check it using this procedure:
1. Disconnect the sensor from the instrument (or junction box if interconnect cable is
used).
3. With the sensor at a temperature between 23°C and 27°C, measure the resistance
between the red and yellow wires with an ohmmeter. The reading should be between
1090 and 1105 ohms.
4. Measure the resistance between the white and blue wires. The reading should be less
than 5 ohms. Now measure the resistance between the green and yellow wires. The
reading should also be less than 5 ohms.
5. Place the ohmmeter to its highest range and measure the resistance between the
shield and white wires. The reading should indicate infinity (open circuit).
•If any one of the resistance checks in the previous steps is incorrect, the sensor is
probably defective. Contact Anderson Instrument Company for details on arrang-
ing a sensor replacement.
•If the resistance checks are correct, the sensor may still be defective. In this case,
more extensive troubleshooting is required. Please consult the Anderson Instru-
ment Company at [phone] for details.
