Full‑Product Introduction for New Original IFM TT2291 Temperature Probe Sensor
1. Product Overview
IFM TT2291 belongs to IFM TT‑series RTD temperature‑sensing probe. It is a passive Pt100 temperature‑measuring element designed to pair with IFM temperature transmitters for process‑temperature detection in hygienic industrial environments. The sensing rod is made of electropolished stainless‑steel 1.4404 (316L). It has a 6‑mm probe diameter and 250‑mm immersion length, built‑in Class‑A Pt100 sensing element complying with DIN EN60751 standard. Equipped with a M12 plug‑in connector with gold‑plated contacts, this probe delivers highly‑accurate temperature signals for liquids and gases. With IP68 and IP69K protection ratings, it withstands high‑pressure washing‑down for food‑beverage, pharmaceutical and water‑treatment systems. This German‑made 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.
2. Main Functions
- High‑Precision Temperature Detection
The built‑in Class‑A Pt100 element accurately measures medium temperature ranging from ‑40 °C to +150 °C, provides reliable resistance‑change signals to matched transmitters.
- Hygienic Installation Performance
Electropolished wetted surface with Ra<0.8 µm reduces medium residue and bacteria reproduction. It can be installed by optional mounting adapters such as E37643 thermowell to fit tanks and pipelines firmlyifm.
- Fast Dynamic Response
Short response time (T05 =1 second, T09=3 seconds) tracks rapid temperature fluctuations inside process pipelines in real‑time. The minimum immersion depth is only 15 mm to get stable readingsifm.
- High Mechanical Durability
The probe tolerates strong vibration (5 g from 10‑2000 Hz) and shock‑load up to 50 g according to DIN‑EN‑60068‑2‑27. Its maximum working pressure can reach 160 bar for high‑pressure pipelinesifm.
- Stable Electrical Transmission
Gold‑plated M12 contacts resist oxidation and avoid poor contact caused by damp workshop environments, ensuring long‑term stable signal transmission.
- Flexible Assembly Method
Ø6‑mm cylindrical probe can be fixed by clamp‑style adapters. Users can select corresponding thermowells for threaded‑weld‑in installation according to on‑site working conditions.
