The 330171-12-41-10-02-05 belongs to Bently Nevada's 3300 XL NSv series eddy current probes. Compared to standard 8mm probes, the NSv series is a high-precision sensor specifically designed for confined installation spaces and small-diameter shafts.
a 3300 5 mm probe
a 3300 XL extension cable (ref 141194-01)
a 3300 XL Proximitor Sensor(ref 141194-01)
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 applications.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.

Petrochemical Industry
Utilizing its explosion-proof certification, it monitors the operational status of high-speed small shafts in hazardous environments to ensure seal system stability.
Air Separation Industry
Used as a Keyphasor sensor in ultra-high-speed (tens of thousands of RPM) turboexpanders to provide precise speed and phase references.
Aerospace Testing Industry
Used in small gas turbine test rigs. Within extremely restricted mounting holes, NSv probes utilize their excellent "side-view suppression" to measure bearing dynamic response.
Rail Transit Industry
It continuously monitors rotor position in on-board environments with high vibration and limited space.
Marine & Subsea Engineering Industry
Installed on the thruster shafts of small submersible pumps or Remotely Operated Vehicles (ROVs) to measure axial movement of thrust bearings, preventing mechanical failure under deep-sea high pressure.
When using the 330171-12-41-10-02-05 probe, ensure that it is used in conjunction with the 3300 XL NSv dedicated preamplifier and extension cable. Do not use it with standard 8mm components to prevent reading failure. During installation, use its 1.2-inch unthreaded section to safely pass through the bracket and monitor the output with a multimeter, precisely locking the initial gap to approximately -10V at the linear midpoint. Simultaneously, ensure it is used in conjunction with an intrinsically safe barrier in explosion-hazardous areas, and never cut the 1.0-meter included cable to maintain system impedance matching. Finally, ensure the coaxial connector is properly insulated and sealed against moisture to ensure signal stability in confined, oily, or humid spaces.
The 330171-12-41-10-02-05 is a 3300 XL series 8 mm Reverse Mount Eddy Current Proximity Probe manufactured by Bently Nevada.
How to use products like the 330171-12-41-10-02-05?
To use it, it is typically threaded into the mounting hole from the inside of the machine's bearing housing (or via a dedicated reverse mount bracket) facing outwards, adjusting the gap between the probe tip and the shaft surface to the linear region. It cannot work alone and must be connected to a 3300 XL Proximitor via a 3300 XL extension cable.
What is the primary function of the 330171-12-41-10-02-05 in the system?
Its primary function is serving as the "sensor" for the monitoring system, enabling real-time monitoring of axial shift or radial vibration via reverse mounting when external space is limited and a probe cannot be installed from the outside in.
How to determine if the 330171-12-41-10-02-05 is damaged?
After disconnecting the extension cable, measure the resistance between the center pin and the outer shell of the probe's ClickLoc connector using a multimeter. The normal coil resistance for 3300 XL series probes is typically between 5.0 and 12.0 ohms; infinity or near zero indicates damage.
What should be paid attention to in the daily maintenance of the 330171-12-41-10-02-05?
The maintenance focus is on keeping the ClickLoc connector clean and never letting oil or dust contaminate its interior, which affects measurement accuracy; additionally, sharp bends in the cable must be avoided, keeping the bend radius above 25.4 mm.
