Bently Nevada 330851-04-000-040-10-01-00 3300 XL 25 mm Side-Exit Proximity Probe
A 25 mm configuration with smooth 1.06 in diameter, side exit for differential-expansion measurement on medium and large steam turbines.
Key Information
330851-04-000-040-10-01-00 is a Bently Nevada 3300 xl 25 mm side-exit proximity probe identified by its complete configurable part number. It is intended for differential-expansion measurement on medium and large steam turbines.
The complete code defines the sensing family and its mechanical and electrical arrangement. Probe diameter, case geometry, cable or system length, connector and approval details must remain together.
Functions
- Provides non-contact eddy-current measurement of a conductive shaft or target.
- Supports differential-expansion measurement on medium and large steam turbines.
- Uses the 25 mm configuration defined by 330851-04-000-040-10-01-00.
- Carries the documented 1.0 m (3.3 ft) connection arrangement.
- Maintains the exact mechanical fit through smooth 1.06 in diameter, side exit.

Installation
- Verify the full 330851-04-000-040-10-01-00 nameplate before disturbing the existing probe loop.
- Confirm case geometry, penetration, mounting thread and available adjustment range.
- Route the cable clear of sharp bends, hot surfaces and electrical interference.
- Keep the probe, extension cable and signal conditioner within the same compatible system family.
- Set the probe gap and validate static and dynamic response before enabling protection logic.
Lifecycle
- 330851-04-000-040-10-01-00 is classified as 3300 xl configurable probe component.
- Keep the full order code, photographs and measured dimensions in the maintenance record.
- Treat any change in probe diameter, cable length, connector, approval or case style as an engineering review.
- For legacy 7200 hardware, assess a complete-loop migration rather than mixing current and legacy components.
