334Digital Inductive ConductivityTransmitter• Optimal solution for conductivitymeasurements in difficult fluids (polluted, dirty...)• PEEK/PPA version for CIP applications8226• Large range of process connections withvarious fittings for DN 15 to 200• Muti language, menu-guided operationType 8226 can be combined with...Type S020Insertion fittingType 6642Solenoid valveType 2031Diaphragm valveType 2031Continuous controlType 8640/8644Valve islandsSensorsThe Type 8226 conductivity transmitter combines aconductivity sensor and an electronic module withdisplay in an IP 65 enclosure. The sensor componentconsists of a pair of magnetic coils in a PVDF orPEEK housing.The cell constant is an average value over the wholemeasuring range. It can be re-adjusted depending onapplication.The integrated temperature sensor for automaticcompensation is a standard feature in the conductivitysensor housing.The transducer component converts the measuredsignal and displays the actual value.The conductivity transmitter can be installed into pipesby using Insertion fitting Type S020 available in stainlesssteel, brass or plastics.Technical dataPipe diameter DN 15 to 200 (fitting Type S020, see pages 340 to 347)MaterialsHousing, cover, lid, nutFront panel folioWetted partsFittingSensor holderSealMeasuring rangeConductivity measurementTemperature measurementAccuracyConductivity measurementTemperature measurementAmbient temperature 0 up to 60 °CRelative humidityFluid temperaturePC glass reinforced fibre (if PVDF sensor)PPA glass reinforced fibre (if PEEK sensor)PolyesterStainless steel (1.4404 / 316L), brass, PVC, PP, PVDFPVDF or PEEKFKM or EPDM0.... 2 S/cm (conductivity) or 0.... 10 kΩ.cm (resistivity)-40... 120 °C±2% o.R.* from 100 μS/cm to 2 S/cm±5 °C from 0 to 100 °C and±1 °C from -40°C to 0°C and from 110 °C to 120 °C≤ 80%, non condensed50 °C (fitting in PVC) - 80 °C (fitting in PP) - 100 °C (fitting inPVDF, stainless steel, brass)Temperature compensation Automatic (with standardized integrated temperature sensor) -reference temperature 25 °CFluid pressure PN6 (see pressure-temperature chart, page 339)Electrical connection Cable plug DIN EN 175301-803 or cable glands M 20 x 1.5Voltage supply cable Shielded; cross-section: max. 1.5 mm 2Protection classVoltage supplyCurrent consumption with sensorwith relayswithout relayOutputRelaysIP65 with cable plug mounted and tightened12 - 30 V DC (regulated ±5%) or 115/230 V AC12 V DC-supply: 150 mA24 V DC-supply: 90 mA115/230 V AC-supply: 150 mA12 V DC-supply: 70 mA24 V DC-supply: 60 mA115/230 V AC-supply: 150 mA4-20 mA programmable (3-wire); proportional toconductivity or temperaturemax. load: 1000 Ω at 30 V DC, 800 Ω at 24 V DC,450 Ω at 15 V DC, 330 Ω at 12 V DC2 relays, freely programmable, 3A, 230 V ACSubject to modifications
