Full\u2011Product Introduction for New Original IFM TT2291 Temperature Probe Sensor<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
IFM TT2291 belongs to IFM TT\u2011series RTD temperature\u2011sensing probe. It is a passive Pt100 temperature\u2011measuring element designed to pair with IFM temperature transmitters for process\u2011temperature detection in hygienic industrial environments. The sensing rod is made of electropolished stainless\u2011steel 1.4404 (316L). It has a 6\u2011mm probe diameter and 250\u2011mm immersion length, built\u2011in Class\u2011A Pt100 sensing element complying with DIN EN60751 standard. Equipped with a M12 plug\u2011in connector with gold\u2011plated contacts, this probe delivers highly\u2011accurate temperature signals for liquids and gases. With IP68 and IP69K protection ratings, it withstands high\u2011pressure washing\u2011down for food\u2011beverage, pharmaceutical and water\u2011treatment systems. This German\u2011made original probe complies with RoHS requirements without refurbished components. It needs to cooperate with separate signal processing units to output standard signals for PLC systems.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. High\u2011Precision Temperature Detection\n
    <\/div>\n

    The built\u2011in Class\u2011A Pt100 element accurately measures medium temperature ranging from \u201140\u202f\u00b0C to +150\u202f\u00b0C, provides reliable resistance\u2011change signals to matched transmitters.<\/li>\n

  2. Hygienic Installation Performance\n
    <\/div>\n

    Electropolished wetted surface with Ra<0.8 \u00b5m reduces medium residue and bacteria reproduction. It can be installed by optional mounting adapters such as E37643 thermowell to fit tanks and pipelines firmlyifm.<\/li>\n

  3. Fast Dynamic Response\n
    <\/div>\n

    Short response time (T05 =1 second, T09=3 seconds) tracks rapid temperature fluctuations inside process pipelines in real\u2011time. The minimum immersion depth is only 15\u202fmm to get stable readingsifm.<\/li>\n

  4. High Mechanical Durability\n
    <\/div>\n

    The probe tolerates strong vibration (5 g from 10\u20112000 Hz) and shock\u2011load up to 50 g according to DIN\u2011EN\u201160068\u20112\u201127. Its maximum working pressure can reach 160 bar for high\u2011pressure pipelinesifm.<\/li>\n

  5. Stable Electrical Transmission\n
    <\/div>\n

    Gold\u2011plated M12 contacts resist oxidation and avoid poor contact caused by damp workshop environments, ensuring long\u2011term stable signal transmission.<\/li>\n

  6. Flexible Assembly Method\n
    <\/div>\n

    \u00d86\u2011mm cylindrical probe can be fixed by clamp\u2011style adapters. Users can select corresponding thermowells for threaded\u2011weld\u2011in installation according to on\u2011site working conditions.<\/li>\n<\/ol>\n<\/div>\n
