The 330171-00-08-10-02-05 is a 3300 XL 8mm / 3300 5mm series eddy current proximity probe manufactured by Bentley Nevada Corporation, USA. It is primarily used in industrial automation and machinery condition monitoring systems for the precise measurement of shaft vibration and displacement in rotating machinery.
3300 5 mm probe
3300 XL extension cable
3300 XL Proximitor Sensor
When combined with a 3300 XL Proximitor Sensor and XL extension cable, the system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. The system can measure both static (position) and dynamic (vibration) data. Its primary use is in vibration and position measurement applications on fluid-film bearing machines, as well as Keyphasor measurement and speed measurement applications6. The system provides an accurate, stable signal output over a wide temperature range. All 3300 XL Proximity Transducer Systems achieve this level of performance with complete interchangeability of probe, extension cable, and Proximitor sensor, eliminating the need for individual component matching or bench calibration.

Oil and Gas
Serves as a Keyphasor (Phase Reference) sensor. By observing a machined notch on the spinning pipeline shaft, it provides a precise once-per-turn pulse. This allows operators to run phase-angle diagnostics, determine exactly where an imbalance is located, and execute field balancing.
Metallurgical and Steel
Operates in high-temperature, dust-heavy environments to track the health of heavy-duty air blowers. It provides continuous data on journal bearing wear, ensuring the blast furnace never loses its vital oxygen air supply due to mechanical failure.
Nuclear Power
Provides critical data for predictive maintenance schedules in high-radiation, restricted-access zones. Because maintenance can only be performed during scheduled refuel outages, the probe provides highly stable, un-drifted data over years of uninterrupted operation.
Liquefied Natural Gas
Measures high-frequency dynamic vibration in extreme, shifting ambient temperatures. The probe’s wide-temperature stability ensures that thermal contraction near cryogenic zones does not cause false alarms or signal drift during the gas liquefaction process.
Marine Propulsion & Shipping Industry
Installed on the ship's main thrust bearing blocks to monitor propeller shaft axial thrust. When a ship changes direction or combats rough seas, the probe assesses whether the hull-to-shaft alignment remains within safe mechanical tolerances.
For accurate measurements and to prevent hardware damage, always ensure strict system length matching (this 1.0m probe must pair with a 4.0m or 8.0m extension cable to form a 5m or 9m system). Note that the sensor is factory-calibrated for AISI 4140 steel; other metals will cause reading errors. During installation, maintain adequate side clearance around the probe tip to avoid signal interference, never exceed the maximum torque of 7.3 N·m (65 in·lbf), and always keep the ClickLoc connectors completely clean, dry, and free of oil.
It is a 3300 5 mm eddy current proximity probe manufactured by Bently Nevada. It is an industrial sensor used to measure critical machinery data like shaft vibration, position, and speed.
How do you use the 330171-00-08-10-02-05 probe?
You thread the probe into a machine housing near a moving shaft. The tip is positioned close to the observed conductive surface (like a steel shaft) without touching it. It then transmits raw signals back to a proximity monitor system.
What components must be paired with 330171-00-08-10-02-05 for it to work?
It must be combined with a 3300 XL Extension Cable and a 3300 XL Proximitor Sensor to form a complete, working transducer system.
Does the 330171-00-08-10-02-05 require field or bench calibration?
No. The system features 100% component interchangeability. You can replace the probe, cable, or sensor without individual component matching or bench calibration.
What applications are best suited for 330171-00-08-10-02-05?
It is primarily designed for vibration and position measurement on fluid-film bearing machines, as well as Keyphasor (phase reference) and speed measurement applications.
