3. Description.
3.1 Product overview
Inductive method :
A ring-type coil is excited at fixed intervals and the response is retrieved on a second coil, which is
linked to the excited coil. The connectivity between the coils (determined by the degree of conductivity)
takes place via the conducting solution.
Economic and successful technology that requiring not enough maintenance and not consumable.
The CTZN sensor offers the following advantages:
• Low operating costs due to reduced maintenance work (no electrolyte changes)
• Greater calibration intervals due to low drift behaviour
• No polarization voltage required • High measuring accuracy, even for low concentrations • Rapid
response times
The sensor features excellent interference immunity thanks to the integrated preamplifier and digital
signal processing. The measured value for conductivity is automatically compensated with the
temperature and transferred without interference to the connected display unit and controller via a
digital interface. The sensor also includes a log book containing the last ten successful calibrations in
the form of a ring buffer.
3.2 Applications
The compact and robust sensor is particularly well suited to the following typical areas of application:
•Urban wastewater treatment
•Industrial effluent treatment
•Surface water monitoring
•Sea water
•Fish farming

3.4 Communication.
3.4.1 Modbus RTU registers.
The link protocol must correspond to MODBUS RTU.
See document: -Modbus_over_serial_line_V1_02.pdf
-Modbus_Application_Protocol_V1_1a.pdf
-Modbus memory for PONSEL digital Sensors :
SENSOR_TramesCom_xxx_UK.xls
The Modbus memory plane is identical for each parameter of the Sensors.
The Modbus protocol for the Sensors allows you to measure the parameter (+ temperature) of the
Sensor and to calibrate the parameter (+ temperature). Furthermore, there are certain numbers of
functions such as: -Select the averaging value
-Read the Sensor description
-Return to default coefficients
-Modify the Sensor address
-Information on measures conducted (Out Of Specification
measures, measures in progress, etc.).
-Date and name of the operator who performed the calibration
-etc.
To have more information on the open PONSEL’s Modbus protocol please consult the last version of
the following documents :

3.4.2 SDI12 frame.
A list of SDI12 registers is available for network communication.
Please ask to our hotline service the documentation on SDI12 communication.
4. Installation.
4.1 Sensor installation option
For the installation of the sensors in condition of immersion or in-pipe insertion, we advise to use
accessories adapted and proposed by AQUALABO.
4.1.1 Accessories for immersion installation.
In immersion condition, it is necessary to maintain the sensor by the body and not to leave the sensor
suspended by the cable at the risk of damaging the sensor.
AQUALABO proposes a range or pole (long version) in order to install the sensor in open basins. It
can be positioned a considerable distance from the basin edge with the bracket suspended for
example.
Please note the following when planning your set-up:
• The fitting must be easily accessible to allow the sensor or the fitting itself to be maintained
and cleaned regularly
• Do not allow the fitting (and thus also the sensor) to swing against and hit the basin edge
• When working with systems involving pressure and/or temperature, ensure that the fitting
and sensor meet all relevant requirements
• The system designer must check that the materials in the fitting and sensor are suitable for
the measurement (chemical compatibility, for instance)
Material
PVC
Admissible temperature

The long poles are available in elbow version, for installations in aeration basin, and straight, for
applications in open channel. Every pole is equipped with an elbowed shutter and with waterproofness
joints. The lower part includes a nozzle which is adapted to the sensor what assures its mechanical
support.
➢Mounting accessories for pole.
The elements of fixation for the poles are flexible and specially studied to adapt themselves to the
different configurations of assembly.

4.1.2 Accessories for PVC pipe-mounting.
Every system of assembly is delivered with an adapter (and the appropriate joints) and one T of
assembly (90 ° for CTZN sensor) to stick on a 90 mm diameter pipe. Its special design type ensures
the correct inflow to the sensor, thus preventing incorrect measurements.
Please note the following when planning your piping set-up:
• The fitting must be easily accessible to allow the sensor or the fitting itself to be maintained
and cleaned regularly
• We recommend bypass measurements. It must be possible to remove the sensor through
the use of shut-off valves
• When working with systems involving pressure and/or temperature, ensure that the fitting
and sensor meet all relevant requirements
• The system designer must check that the materials in the fitting and sensor are suitable for
the measurement (chemical compatibility, for instance)
Mounting system for CTZN sensor (PF-ACC-M-00001)
1 Unscrew the union nut (2) from the PVC flow fitting (3).
2 Guide the sensor cable through the union nut on the fitting.
3 Insert the sensor (1) into the fitting as far as the position shown in the middle image above.
4 Screw the union nut onto the fitting as far as the stop.

5. Startup and maintenance.
5.1 Initial startup
Once the sensor is connected to your terminal, the sensor is settled in its accessory of assembly and
the parameterization has been carried out on the display unit, the sensor is ready for initial startup.
➢Note :
During the introduction of the sensor in measurement environment, wait for sensor’s temperature
stabilization before measure processing.
➢Started :
5.2 Calibration
The calibration of the conductivity sensor is a 2-step process:
- Step 1 (offset): Expose the sensor to the air to perform the first stage of the Calibration process. The
value for this first calibration standard is set to 0 0 μS/cm.
- Step 2 (gain): the sensor is placed in a buffer solution of known conductivity 12,88 mS/cm. Let
stabilize during 5 minutes.
5.3 Maintenance:
The sensor not being sensitive to the fouling, there is no particular maintenance to be planned.
However, assure hthat the central part of the sensor is not blocked.
