      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Bently Nevada 330851-01-000-030-10-00-05. The 3300 XL 25 mm probe observes a turbine rotor collar or ramp in a differential-expansion measurement system.
      Probe-tip material: Polyetheretherketone (PEEK)
      Probe-case material: AISI 304 stainless steel
      Probe lead: 75 Ω triaxial, PFA-insulated FluidLoc cable
      Matched-system output: 0.787 V/mm (20 mV/mil)
      The 01/000/030 case combines a 1 1/4-12 thread, zero unthreaded length and a 3.0 in overall case. Threaded 25 mm probe cases include a locknut with safety-wire holes. The standard FluidLoc lead and front and rear seals limit moisture entry at the tip; the probe design is rated for continuous operation to 200 °C and intermittent exposure to 250 °C.

      Options 10/00/05 select a 1.0 m integral lead, no optional separate armor and multiple approvals. The 25 mm probe and extension cable use high-temperature ClickLoc connectors. A complete 5 m or 9 m system also requires its matching extension cable and 25 mm Proximitor sensor; only that calibrated system has the nominal 0.787 V/mm (20 mV/mil) output and 12.7 mm (500 mil) linear range.

      Differential expansion is measured with two transducers viewing a rotor collar or ramp away from the thrust bearing. Same-side collar mounting gives redundant readings; opposite-side mounting increases measurable travel; a ramp can cover longer movement with compensation and added measurement error. Choose the arrangement from target size and expected axial travel, then move the mounted system through its linear range to verify response.
      Installed-system reference: 3300 XL 25 mm differential-expansion transducer system. Select the turbine bracket from the actual collar or ramp geometry.
      Technical downloads for Bently Nevada 330851-01-000-030-10-00-05: selected original manufacturer pages and a model-specific Apter Power installation guide.
      The technical reference preserves selected original manufacturer pages. The installation guide is prepared by Apter Power for this exact model; apply site procedures and the original equipment documentation during work.
      Turbine application: Bently Nevada 330851-01-000-030-10-00-05 is a 25 mm proximity probe for differential-expansion measurement on a steam turbine. The probe observes relative movement between the rotor and casing through a suitable collar or ramp target.

      Compatibility scope: Use a matched 25 mm probe, extension cable and Proximitor with the approved differential-expansion monitor. The 1 1/4-12 case thread, 3.0 in case and 1.0 m lead must fit the installed bracket and target geometry.
      Installation and commissioning checks for Bently Nevada 330851-01-000-030-10-00-05. Establish the turbine target arrangement and calibrated transducer chain before setting the probe gap.
      Secure the machine

      Isolate the turbine and secure the probe bracket before moving the sensor. Record the original collar or ramp position and installed gap.

      Check the bracket

      Confirm the 1 1/4-12 mount and locknut against the fitted adapter. Prevent bracket movement that could change the gap during operation.

      Verify target travel

      Compare expected axial travel with the target width or ramp geometry. Check clearances at both ends of travel before tightening the probe.

      Protect the connection

      Keep the high-temperature ClickLoc connection clean, dry and free of mechanical strain. Route the 1.0 m lead away from damage and heat beyond its approved rating.

      Match the system

      Use the specified 25 mm extension cable and Proximitor combination. Do not transfer scaling from an 8 mm or NSv channel.

      Confirm the measurement

      Set the gap with the target at the prescribed reference position. Verify channel output and direction of indicated differential expansion over the approved movement check.

      Technical notes

      Installed role: This configured probe belongs to the 3300 XL 25 mm differential-expansion transducer chain.

      System boundary: The system range and scale factor apply only with the matched cable and Proximitor sensor.
