6 3522 Conductivity Measuring range Conductivity 0 to 20 μs; 0 to 200 μs; 0 to μs; 0 to μs; 0 to μs Resolution 0,01 μs; 0,1 μs; 1 μs; 10 μs S411-S428 Conductivity probes Specially designed for use in an industrial environment, these make it possible to cover a very wide measuring range, thanks to versions with temperature sensor, special versions with PVC, PTFE, PVDF body, graphite, steel or platinum electrodes. Conductivity is measured by submerging the two metal electrodes of the probe in the solution to be measured. The passage of current between the two probes allows the electrical resistance of the liquid and therefore its conductivity to be measured. The measurement is influenced by the temperature. In saline solutions, there are variations of 2% / C. This variation can reach 7% / C, therefore the use conductivity probes with no temperature sensor is preferable if the solution being examined remains at a temperature of between 15 C and 25 C.

The result has been obtained by moulding the sensor made using polypropylene reinforced with fibreglass. This sensor offers all the advantages of the inductive cond. measurement method, including the absence of passivation of the conventional conductivity electrodes. All the sensors in the S410/IND range are temperature-compensated, and are also designed for inline, submersion or tank installation.

8 3582 Dissolved Oxygen Measuring range Dissolved oxygen 0 to 20.0 ppm or mg/l - 0 to 200% SAT Resolution 0.1 ppm or mg/l - 1% SAT S423/OXYSENS Main measuring range The oxygen contained in the liquids is measured using the so-called Clark cell system. These cells generate a current proportional to the partial pressure of the oxygen, which can be detected using a suitable signal converter. In order to prevent interference during measuring, the Clark cell is protected by a gas-permeable membrane. The membranes typically used are made from PTFE but, as this material is mechanically fragile, frequent changing is often necessary, along with the related demanding operations (interruption of measurement, replacement of the electrolyte, regeneration of the electrodes). The S423 solves this problem by using a membrane made from OPTIFLOW. Manufactured as a sheet around a layer of steel, it is very stable mechanically and very resistant to chemically aggressive environments as well as high pressure. Thanks to the special construction of the measuring electrodes, this system also makes the sensor totally maintenance-free. Maintenance OXYSENS sensors are maintenance-free, and do not require the replacement of the membrane, electrolyte or regeneration of the electrodes, to measure the oxygen in aqueous samples. Typical applications include water treatment plants and the fish industry.
