Oxygen Measurement - Immersion Assemblies

Process Assembly for 120 mm sensors Application Process assembly for pH glass electrodes, pH ISFET sensors and other 120 mm / 4.72 inch sensors Food Pharmaceuticals Chemicals Water treatment Permanent installation in tanks and pipework Your benefits Cleanable and sterilisable acc. to EHEDG criteria Complies the 3-A standard 74-02 Flush mounted, leak-tight built-in electrode seal (moulded seal) Electropolished surface Ra = 0.4 µm / 1.57*10-5 in or 0.8 µm / 3.15*10-5 in (stainless steel 1.4435, AISI 316L) Different process connections: - DN 25 / 0.98 in nozzle - DN 50 / 1.97 in dairy fitting - TriClamp (3 lengths) - Varivent - APV - Neumo BioControl Up to 10 bar / 145 psi and 140 °C / 284 °F Optional leakage monitoring The most important technical data Process temperature range pH: - 15 ... 140 °C / 5...284 °F Oxygen: - 10 ... 140 °C / 14...284 °F Process pressure range up to 10 bar / 145 psi Ambient temperature Depending on the sensor: pH glass electrode or IsFET pH sensor: > - 15 °C / 5 °F Oxygen sensor: < - 10 °C / 14 °F Leakage monitoring Leakage monitoring indicates any leaks in the moulded seal (pos. 2 in figure on p. 3). In the event of a leak, small amounts of fluid escape through the monitoring hole. The moulded seal must then be replaced. CIP/SIP cleaning The assembly can be sterilised and cleaned acc. to EHEDG criteria. You will receive a 3-A certificate depending on the process connection.
