Product Overview

330851-02-000-050-10-00-05 is a Bently Nevada 3300 XL 25 mm proximity probe with an M30 x 2 threaded case.

The code specifies 0 mm unthreaded length, a 50 mm case, 1.0 m total probe length, no armor and the multiple-approval option. The 50 mm case is identified as a non-standard, extra-charge configuration rather than a normally stocked geometry.

The 25 mm system is used principally for differential-expansion measurements. Confirm target size, mounting clearance, matched extension cable, Proximitor Sensor and system calibration before installation.

Selection, Installation & Diagnostics

Selection

  • Confirm the 50 mm non-standard case, M30 x 2 mounting thread and code 05 approval requirement.
  • Verify the 61 mm minimum target diameter and the complete 25 mm system architecture.

Installation

  • Provide clearance for the large probe body and use the documented 68 N m mounting torque.
  • Maintain the 25.4 mm minimum cable bend radius and support the unarmored PFA-jacketed cable.

Diagnostics

  • Check target alignment, installed gap and differential-expansion geometry before changing monitor scaling.
  • Troubleshoot the probe, extension cable and 25 mm Proximitor Sensor as one calibrated chain.

Frequently Asked Questions

What machine application is documented for 330851-02-000-050-10-00-05?

The 3300 XL 25 mm system is designed for differential-expansion measurement on mid-size to large steam turbine generators. It measures the difference in growth between the turbine rotor and the machine casing through a collar or ramp arrangement.

What does the 50 mm case option mean when ordering 330851-02-000-050-10-00-05?

Fifty millimetres is not one of the listed standard metric case lengths, so the ordering table treats it as a non-standard length with an additional charge. This exact part number is also absent from the document's stocked-probe list.

Which mounting dimensions must match before 330851-02-000-050-10-00-05 is installed?

The probe uses an M30 x 2 threaded case, 0 mm unthreaded length and a 50 mm overall case. The published recommended torque for threaded probe cases is 68 N m, and the cable route must maintain a 25.4 mm minimum bend radius.

How does the one-metre lead on 330851-02-000-050-10-00-05 fit into the complete 25 mm system?

The matched system is 5 m or 9 m including the extension cable. A one-metre probe lead therefore belongs with the manufacturer-documented extension-cable and Proximitor length that completes the selected 5 m or 9 m chain.

What target and gap references apply when commissioning 330851-02-000-050-10-00-05?

The published system specifications use an AISI 4140 steel flat target at least 61 mm in diameter and a 7.0 mm reference gap. The 12.7 mm linear range is stated for the matched 25 mm chain under those defined conditions.

Can 330851-02-000-050-10-00-05 be assumed to have a factory pressure test for a steam-turbine DE installation?

No. The probe uses a Viton O-ring and compression seal, but the manufacturer states that probes are not pressure-tested before shipment. An application that requires a tested pressure seal therefore needs that requirement addressed separately.

What replacement boundary applies when 330851-02-000-050-10-00-05 is used to migrate from a standard 7200 25 mm, 7200 35 mm or 25 mm DE Integral system?

The manufacturer requires the probe, extension cable and Proximitor Sensor to be replaced with 3300 XL 25 mm components. The matched Proximitor output is documented as identical to the legacy systems, which allows the monitor configuration to remain unchanged within that stated migration path.

How can a sliding bracket support commissioning and periodic verification of 330851-02-000-050-10-00-05?

The documented sliding bracket lets the probe assembly move relative to the rotor collar so the system can be checked across its range. A dial-indicator verification kit provides a movement reference while the bracket helps keep the transducer aligned and perpendicular to the rotor.
