OPTISENS IND 1000
Dimension [mm] Dimension [inch]
The OPTISENS IND 1000 sensor features a compact and extremely rugged design as well as a
wide measuring range. The meaurement coils are completely enclosed and there is no direct
contact of the measurement coils to the medium. This feature makes it corrosion resistant and
suitable for measurement mediums with a high dirt load.
The body is either out of PP or PVDF. The sensor features an exposed or internal Pt1000
temperature sensor which reading is used for the temperature compensation of the conductivity.
Combined with a signal converter, an extremely reliable and cost-effective measuring systems
can be created. Inductive measurement systems are very well suited for conductivity
measurements in severely contaminated and aggressive media in all industries.

OPTISENS IND 1000
Thanks to its compact design, the sensor can be installed in pipelines with relatively small
diameters. The immersion depth from screw fitting to sensor tip is just 81 mm and such suitable
for DN50 pipes. The measurement field requires a minimum of 20 mm free space around the
sensor coils to not have an impact onto the cell factor.

3.1 General notes on installation
INFORMATION!
Inspect the packaging carefully for damages or signs of rough handling. Report damage to the
carrier and to the local office of the manufacturer.
INFORMATION!
Do a check of the packing list to make sure that you have all the elements given in the order.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
3.2 Storage and Transport
• Store the conductivity measuring system in its original packaging in a dry and dust-free
location. Keep it away from dirt.
• The original packaging serves the protection of the equipment. Therefore always use it for
transport or return to the manufacturer.
OPTISENS IND 1000
3.3 Installation procedure
Most new inductive sensors get installed not needing a further calibration and adjustment of the
cell factor. However, it is good practice to calibrate a sensor at time of installation into its final
measuring location. The cell factor might vary ±15%. Follow the installation order:
1. Unpack the sensor.
2. Connect the sensor to the signal converter.
3. Program the cell factor of the inductive sensor used (PP version c=6.25, PVDF version c=4.65)
4. Adjust the cell factor against a known value after the following step or calibrate the sensor in
a standard solution (e.g. 25 mS/cm). Make sure the coils are minimum 20 mm away from any
surface and fully immersed in the solution.
5. Install the sensor into its final measuring location.
The required steps are explained in the following sections.

3.4 Pre-installation requirements
CAUTION!
•
Unpack the sensor carefully!
•
Make sure that the sensor is clean.
INFORMATION!
•
Nothing shall block the measurement hole within the sensor.
•
Consider a large enough distance from metal or plastic pipe walls!
The sensor can be installed into the SENSOFIT FLOW 1000 assembly which is available in DN32,
DN40 and DN50.
If installed into small diameter pipes like DN32 and DN40 the minimal free diameter of 20 mm
around the sensor coils can not be kept. In these cases the cell factor has to be adjusted. The
best method is to do an inline calibration against a reference measurement. In case this is not
possible try to achive similar dimensions and materials in a calibration beaker. In case both is
not possible you can adjust the cell factor by multiplying it by a factor. Every sensor coil is
different or might vary in its characteristics. A multiplier can only be given as an approximate
indication. Within a SENSOFIT FLOW 1000 with DN32 you do have ~8mm and with DN 40 ~14mm
free space around the sensor available, both being less then 20mm. Mentioned multipliers are
approximates only. Therefore the recommendation is to install in a pipe equal or bigger then
DN50.

3.7 Installing the sensor
3.7.1 General installation instructions
WARNING!
Ensure that the pipe is without pressure before installing or removing a sensor!
INFORMATION!
Be sure that the tube is completely filled with water, otherwise the measuring reading is wrong.
INFORMATION!
During installation you should fix a shut-off valve in front of and behind the instrument so that
the sensor can be taken out of the bypass in case of check.
INFORMATION!
To achieve reliable measuring results, note the following items:
•
Always install the sensor in the designated flow through assembly or ensure that the pipe
diameter is large enough.
•
The sensor must always have full contact with the measuring medium.

INFORMATION!
If you choose no compensation, the measured conductivity will most likely deviate from the
actual conductivity. The reason is that the conductivity of a specific medium varies depending on
the temperature of the medium.
The menu for temperature within the menu process input (A or B) offers the following options:
• Pt1000

4.3.3 Calibrating measurement
Verification and in case of need calibration is necessary in regular intervals or good practice
when installing a new sensor. A sensor should be recalibrated if the verification within a
standard solution shows a too high difference in actual reading.
When calibrating a conductivity measurement, keep in mind that the measuring system as a
whole is calibrated, and not only the electrode.
To avoid alarms on the distrubted control system (DLC) when temporarily removing the sensor
(i.e. for maintenance), the converter has a hold function. This function "freezes" all outputs (i.e.
the display and the current outputs) of the last measured value.
INFORMATION!
As an indication that the manual hold function is active, the "warning sign" in the upper left
corner of the display appears. Meanwhile the status messages show "checks in progress". For
more details about how to select the manual hold function refer to the signal converter manual.

• If you calibrate a sensor, make sure that the sensor is correctly connected to the converter.
• Check the sensor for damages or dirt deposits.
• During the calibration procedure, you will have to dip the sensor into a standard solution.
Provide a suitable vessel.
After activating the manual hold function and the preparative measures, you can get access to

measurement of the "stored value" and the input of the reference value. Otherwise this could
result in a wrong calibration.

6.1 Measuring principle
6.1.1 Inductive conductivity measurement
The inductive measurement method enables largely maintenance-free acquisition of specific
conductivity, even in the toughest media conditions. In the principle of inductive measurement,
the sensor consists of a sender-recipient-coil.
When a magnetic field is generated by an electrical coil and a second electrical coil is placed
next to it, a certain amount of electric energy will be transferred to it. In an inductive conductivity
sensor, the process media flows directly through the middle of both coils. The amount of energy
transferred from the primary to the secondary coil is directly proportional to the electrical
resistance of the solution.
