5. DESCRIPTION
5.1. Area of application
The device is intended solely for the measurement of the conductivity.
The device is used to transmit the conductivity measured to a
4...20 mA loop.
5.2. General description
5.2.1. Design
The device comprises:
• A sensor for measuring physical parameters, comprising:
- 2 electrodes which measure an impedance in Ohm
- a Pt1000 temperature probe which converts the temperature
of the fluid into resistance (in W).
• an acquisition / conversion module of measured physical data:
- acquisition of the impedance measured in Ohm
- conversion of the measured impedance into conductivity units
- acquisition of the resistance measured and conversion into
temperature.
The device operates on a 2 wire system and needs a 12...36 V DC
power supply. Electrical connection is made:
- Either by one M12 5-pin male fixed connector
- Or via a cable gland on a 5-pin terminal block.

understood the contents of these Operating Instructions.
▶ In particular, observe the safety recommendations and intended
use.
▶ The device/installation must only be adjusted by suitably trained
staff.

WARNING
Danger due to nonconforming commissioning.
Nonconforming commissioning could lead to injuries and damage
the device and its surroundings.
▶ Before commissioning, make sure that the staff in charge
have read and fully understood the contents of the Operating
Instructions.
▶ In particular, observe the safety recommendations and intended
use.
▶ The device/installation must only be commissioned by suitably
trained staff.
9.2. Description of the connection box
The box contains the terminal block for electrical connection and
elements used for adjustment:
• a selector of the conductivity or temperature range associated
with the 4...20 mA output
• a green LED to indicate that the device is energized
• a red LED to:
- indicate the type of probe that is fitted on the device (see chap. 9.3)
- indicate a problem (see chap. 10.5)
• a push-button (not used).

9.3. Choosing the conductivity or
temperature range associated
with the 4...20 mA output
The following procedure is valid for the devices with a series
number equal or higher than 3000. See the name plate of
the device.
Upon power-up and every ten seconds afterwards, the red LED flashes:
• once if the device is equipped with a probe C=1
• twice if the device is equipped with a probe C=0,1
• three times if the device is equipped with a probe C=0,01
The selector (see Fig. 18) allows for choosing the conductivity
or temperature range associated with the 4...20 mA output . The
following tables give, depending on the cell constant and on the
position of the selector (from 0 to 9 and A to F, the uneven positions being marked by a full stop), the conductivity or temperature
range associated to the 4...20 mA output, the applied temperature
compensation and the measuring range of the recommended
conductivity.
The compensation graph “NaCl” is valid for the 10 to 90 °C temperature range and a concentration of 0,2 %.

9.4. Checking the cell constant of the
conductivity sensor
Each sensor is delivered calibrated.
Take the temperature compensation into account.
The following procedure makes it possible to check the exactness of
the device:
→ Prepare a calibration solution adapted to your process or the
sensor (see chap. "11. Spare parts and accessories").
→ Place the sensor into the calibration solution.
→ Wait for the temperature to stabilise.
→ Check the exactness of the measured value transmitted by the
transmitter to the acquisition system (PLC,...).
→ If necessary, correct the measure on the acquisition system
(PLC, ...).
