326Digital O.R.P. Transmitter,compact version• Programmable O.R.P.-transmitter functionsfor all kinds of O.R.P.-measurement tasksSensors 8206Type 8206 can be combined with...Type S020Insertion fittingType 6642Solenoid valveThe compact O.R.P.-transmitter combines an O.R.P.-sensor and an electronic module with a display in anIP65 enclosure.The sensor component consists of a replaceablecombination O.R.P. electrode screwed into the sensorhousing. The measured signal is conveyed to thetransmitter via a coaxial plug.The transmitter component converts the measuredsignal, displays the actual value.The O.R.P.-transmitter can be installed into pipe byusing Insertion fitting Type S020 or suitable installationmaterials. It can also be installed in tank or containersby using an industrial immersion fitting.• Compact version with integrated O.R.P.electrodes• Large range of process connections withvarious fittings• Multi language, menu-guided operationType 2031Diaphragm valveTechnical dataType 2031Continuous controlType 8640/8644Valve islandsPipe diameter DN 15 to 200 (fitting Type S020, see pages 340 to 347)MaterialsHousing, cover, lid, nutFront panel folioWetted partsFittingSensor holderSealMeasuring rangeMinimal rangeSensor elementFluidMin. conductivityHousingFluid pressure / Fluid temperatureMax. pressure at max. temperatureDiaphragmReference electrolyteAccuracyPCPolyesterStainless steel (1.4404 / 316L), brass, PVC, PP, PVDFPVDFFKM (EPDM included in delivery)-2000... +2000 mV50 mV (corresponding to 4-20 mA)Electrode: UNITRODE O.R.P.Clean, contaminated, with low conductivity or containingsulfides/proteins2 μS/cm (200 kΩ.cm)Glass shaft0-6 bar / 0-130 °C (0 - 87psi / 32 - 266 °F)4 bar (58psi)2 clogging free “Single pores”Polymer±3 mV depending on electrode calibrationAmbient temperature 0 up to 60 °C (32 up to 140 ° F)Relative humidityFluid temperature≤ 80%, non condensed50 °C / 122 °F (fitting in PVC) - 80 °C / 176 °F (fitting in PP)- 100 °C / 212 °F) (fitting in PVDF, stainless steel, brass)Fluid 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 - filtered and regulated< 80 mA< 20 mA4-20 mA programmable (3-wire with relays, 2-wire without relay);proportional to O.R.P.max. load: 700 Ω at 30 V DC,400 Ω at 24 V DC, 100 Ω at 15 V DC2 relays, freely programmable, 3A, 230 V ACSubject to modifications
