A generator (1) generates an alternating magnetic field in the primary coil (2) which induces a current in the
medium (3). The strength of the induced current depends on the conductivity and thus the ion concentration
of the medium. The current flow in the medium generates another magnetic field in the secondary coil (4).
The resulting current induced in the coil is measured by the receiver (5) and processed to determine the
conductivity.

• Accurate measurement in media or solutions with
a high soiling degree and a tendency to deposition
• Complete galvanic separation of measurement and
medium
Important properties of
Smartec S CLD132
C07-CLXixxxx-15-0x-00-xx-001.eps
• Hygiene
The sensor, injection-moulded from highly chemically, mechanically and thermally resistant PEEK
(polyether ether keton), does not have joints or crevices and is therefore hygienically safe.
• Temperature measurement
– For applications requiring quick temperature measurement (e.g. CIP return, phase separation at various
temperatures), the Pt 100 temperature sensor is installed in a stainless-steel thermal conductivity socket
that is sealed by a Chemraz O-ring. This ensures extremely fast temperature response times (t
< 5 s).
90
– For high-load applications, particularly for alternating thermal load due to very frequent sterilisation cycles
or temperature shocks, the Pt 100 temperature sensor is embedded in the PEEK sensor body thus
eliminating the need for a seal. This ensures a long service life.
This sensor version can also be applied at underpressure.
• Temperature compensation
Smartec S CLD132 offers the following types of temperature compensation:
– Linear compensation with freely selectable temperature coefficient α
– Compensation according to IEC 746-3 for NaCl
– Compensation with freely programmable coefficient table with 10 elements maximum
• Process temperature
The use of special components and materials makes the sensor suitable for continuous exposure to
temperatures of +125 °C. Short-time (max. 30 min.), it will work at +140 °C for sterilisation.
• Concentration measurement
The transmitter can be switched from conductivity operating mode to concentration operating mode. The
concentration operating mode provides one freely programmable as well as various predefined concentration
curves, especially for common CIP solutions. This enables a direct display of the concentration in %.
• Remote parameter set switching
Smartec S CLD132 can be ordered with remote parameter set switching (measuring range switching, MRS)
enabling you
– to cover a wide measuring range
– to adjust temperature compensation when changing the product
– to switch between concentration curves.

Installation
Installation instructions
In narrow installation conditions, the ion flow in the
medium is affected by the pipe walls. This effect is
compensated by the so-called installation factor. The
installation factor can be entered in the transmitter or
the cell constant can be corrected by multiplication
with the installation factor to ensure correct
measurement.
The value of the installation factor depends on the
diameter and the conductivity of the pipe as well as
the sensor’s distance from the wall.
If the distance from the wall is sufficient (a > 15 mm,
from DN 65), it is not necessary to consider the
installation factor (f = 1.00).
If the distance from the wall is smaller, the installation
factor increases in case of electrically insulating pipes
(f > 1) and decreases in case of electrically conductive
pipes (f < 1).
The installation factor can be measured using
calibration solutions or it can be approximately
determined from the diagram below.

C07-CLD132xx-11 -06-00-en-003.eps
Note!
• Clamp connection
Sensors with clamp connections can be fixed using sheet metal brackets or solid brackets.
Sheet metal brackets have a lower dimensional stability, uneven bearing surfaces causing point loads and
sometimes sharp edges that can damage the clamp.
We strongly recommend to always use solid brackets because of their higher dimensional stability. Solid
brackets may be applied over the total pressure-temperature range (see diagram on page 11).
• Threaded connection
Sensors with threaded connections are supplied with expansion bellows (compensator) to be able to align
them in flow direction. The two O-rings (Viton) of the expansion bellows have no sealing function and are
not in contact with medium. The process is usually sealed off by PTFE tape on the G 1½ thread.
