2.2 Device description
2.2.1 Conductivity sensor
The OPTISENS COND 1200 sensor is a conductive cellular measurement medium with an
integrated temperature sensor (Pt1000). It contains two stainless steel electrodes with PVDF
insulation that prevent proneness to soiling. It is available in various cell constants (c = 0.01,
0.05, 0.1, 0.2, 1.0) and thus covers a wide area of use. The conductivity sensor have a
standardised robust design and a long lifespan. In combination with a signal converter, it is
possible to create extremely reliable low-cost measurement systems, which is suitable for a
wide range of water analysis measurement tasks.
The conductive measurement principle is characterised by high sensitivity, especially at low
conductivity values. For this reason, the sensor is perfect for low-contamined, non-corrosive
media such as pure water, steam and cooling water as well as service water.
If the values exceed 20 mS/cm and in case of heavy soiling or danger of corrosion by the medium,
it is highly recommended to make use of the inductive measurement with the IND 1000 (see
handbook IND 1000).
