This double lock effectively protects theprocess from any intrusion of contamination after insertion of the electrode/ sensor. The housingalso enables the electrode/sensor to be withdrawn from the process for maintenance purposesunder sterile conditions while the process is still running. After servicing or exchange,the electrode/ sensor can be steam-sterilized within the housing before reinsertion into theprocess medium, without any fear of contamination.The InTrac 797 is easily installed through the side of the reactor or vessel, using a 25 mmweld-in socket (Ingold type or METTLER TOLEDO safety socket). It is available either as amanually operated version or with pneumatic drive.SpecificationsPressure in reactor:Temperature rangesRetractable member:Headpart:Weld-in socket:Insertion length:MaterialsProcess wetted:Headpart:Seals process wetted:Other seals:Flushing connections:InTrac 797-M/75, InTrac 797-P/75, InTrac 797-M/75 FSCdependant on sensor specification, but not more then 6 bar0...130°C, steam-sterilizable0...80°CID = 25 mm, L = 40 mm, 15° chamferH = 75 mmStainless steel, DIN 1.4435 with 3.1b material certificatePOM (polyoxymethylene) and PP (polypropylene)Viton ® FDANitrile, BunaG 1 ⁄ 8 " threadINTERNEThttp://www.mtpro.comOrdering InformationDesignationOrder no.InTrac 797-M/75 (manual) 00 797 3007InTrac 797-P/75 (pneumatic) 00 797 3009InTrac 797-M/75 FSC (for turbidity measurements) 00 797 3012(Fitting sets for steam lines see «spare parts and accessories»)Standard-ElectrodesThe recommended gel-filled electrodes require little maintenance, because the electrolyte does not need to be refilled.Designation Order no.
