1 Function
The sensor is used for measuring electrolytic conductivity in aqueous sample media. The sensor
works on the inductive measuring principle.
The sensor’s signal processing electronics are integrated in the sensor housing.
The sensor is factory-calibrated.
The sensor needs a 12 ... 24 V DC supply and has a 4 ... 20 mA current loop output, all contained in
a 6-wire, unshielded cable.
The 4 ... 20 mA cable transmitter is housed in a moulded module adjacent to the sensor body on the
cable.
The cable length is: 2 m between the sensor and cable transmitter and 10 m between the cable
transmitter and monitor.
Do not shorten or otherwise modify the cable.
The sensor can be fitted with a flange and has a ½” BSP thread.
The sensor has an integral temperature measurement, which is used to calculate the temperature
compensation of the conductivity output value. You do not need an additional temperature sensor
for temperature compensation of the output signal. Temperature compensation is done within the
sensor’s electronics and the standard setting is 1.7 %/°C.
The sensor has three measuring ranges:
n0 ... 2 mS
n0 ... 20 mS
n0 ... 200 mS
Model Temperature Fixing thread Interface Electronics
ICT 8 0 ... 50.0 °C ½' BSP parallel TTL Internal
Typical applications
The sensor is predominantly designed for appli‐
cations in water treatment and for water moni‐
toring, e.g.:
nContaminated waste water and process
water
nAir conditioning plants and chillers
nBlowdown control in cooling towers,
nFlushing baths,
nVehicle washing systems,
nSalt water desalination (feed),
nSwimming pool water control.
You can also use the sensor in contaminated
water, which is chemically inert to PP/EPDM
(depending on the design of the sensor).

2 Storage and transport of the sensor
User qualification: instructed user
Original packaging
Damage to the product.
–
Only transport, ship and store the
sensor in its original packaging.
–
Retain the packaging including the
polystyrene inserts.
2.1 Storage
Permissible ambient temperature: -10 °C ... +60
°C.
Humidity: maximum 90 % relative air humidity,
non-condensing.
Other: No dust, no direct sunlight.
Maximum storage period of the sensor in its
original packaging and normal atmosphere: 2
years.
2.2 Transport
The sensor should be transported in its original
packaging and in compliance with the permis‐
sible environmental conditions. No further spe‐
cial conditions have to be observed in relation
to transport.
2.3 Packaging material
Dispose of packaging material in an environ‐
mentally responsible way. All packaging com‐
ponents carry the corresponding recycling code
.

I. Minimum distance of the sensor body to
other surfaces
Ensure that there is unimpeded access for subsequent calibration.
The mounting must be secure and low-vibration.
Avoid direct sunlight.
Make sure that the medium flows correctly through and around the sensor.
Maintain a minimum distance from the sensor to the tube wall when installing in pipework, as
described in Fig. 1.
Fit the sensor into a suitable bypass fitting, as described in the operating instructions for the
bypass fitting.
