330851-01-000-020-90-00-00 is a Proximity Probe designed and developed by Bently Nevada. The Transducer System is appropriate for detecting differential expansion (DE) on mid-size to large steam turbine generators, which is caused by a difference in growth rates between the turbine rotor and the machine stator (casing).


  • The 3300 XL 25 mm probe is built to last in the hardest steam turbine DE settings. It can work continuously and accurately in temperatures as high as 200 °C , and it can resist intermittent high temperatures as high as 250 °C . The 25 mm probe has a front and rear seal that, when combined with the FluidLoccable (which is standard on all 25 mm probes), keeps moisture out of the probe tip.
  • On the probe and extension cable, special high-temperature connections are also standard. To keep the connectors free of contamination, each probe and cable come with connector protectors and a disposable connector protector installation tool.
  • The probe lead's ClickLoc connector incorporates a detachable collar that allows the cable to be routed through tight spaces.


  • Tip Material: Polyetheretherketone (PEEK).
  • Case Material: AISI 304 stainless steel (SST).
  • Cable Specifications: 75 ohm triaxial, perfluoroalkoxyethylene (PFA) insulated FluidLoc probe cable in the following total probe lengths: 1, 5 or 9 metres.
  • Operating and Storage Temperature: -35 degrees Celsius to +200 degrees Celsius
  • Short Term Operating and Storage Temperature: +250 degrees Celsius max for less than 24 hours
