The 330171-00-10-10-02-05 belongs to Bently Nevada's 3300 XL NSv series eddy current probes. As it belongs to the NSv branch, it is a precision displacement sensor designed for extremely compact 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.

Industrial Refrigeration
Used for rotor monitoring in centrifugal chillers. It measures axial displacement within compact structures to prevent thrust bearing failure.
Petrochemical Industry
Applied to small seal gas booster pumps. Utilizing its 05 explosion-proof certification, it monitors high-speed small shafts in hazardous areas.
Air Separation
Used as a Keyphasor sensor in ultra-high-speed turboexpanders to provide phase references for balancing and speed.
Rail Transit
Applied to small centrifugal units in train HVAC systems. It monitors rotor radial position in high-vibration, limited-space on-board environments.
Semiconductor Manufacturing
In vacuum pumps supporting cleanrooms, it monitors the shaft centerline orbit of high-speed rotors to ensure power system stability.
When using the 330171-00-10-10-02-05 probe, ensure it is used with the 3300 XL NSv dedicated preamplifier and extension cable. Do not use it with standard 8mm components to prevent reading failure. During installation, utilize its 1.0-inch ultra-short fully threaded housing to fit in tight spaces, and monitor the output with a multimeter to precisely lock the initial gap at approximately -10V linear midpoint. Ensure it is used 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 moisture-proofed to ensure signal stability in confined, oily, or humid spaces.
The 330171-00-10-10-02-05 is a 3300 5 mm Reverse Mount Eddy Current Proximity Probe manufactured by Bently Nevada. It is a non-contacting sensor used to measure shaft vibration and displacement on rotating machinery
How to use products like the 330171-00-10-10-02-05?
This product uses a reverse-mount design (threaded from the inside of the machine outward or using a reverse mount bracket) with the tip facing the metal shaft. It cannot work alone, and its connector must be attached to a Proximitor via an extension cable.
How to determine if the 330171-00-10-10-02-05 is damaged on site?
Disconnect the extension cable and measure the coil resistance between the center pin and outer shell of the connector with a multimeter. For this 5 mm probe, normal resistance is typically between 5 and 12 ohms; infinity or near zero indicates damage.
What is the main difference between the 330171-00-10-10-02-05 and standard 8 mm probes?
It features a smaller probe diameter (5 mm) and a narrower magnetic field, combined with a reverse-mount style, making it ideal for precision situations where external bearing housing space is fully occupied and the shaft diameter is small.
What certification does 05 at the end of the code 330171-00-10-10-02-05 represent?
The code "05" represents Multiple Agency Approvals (such as ATEX, IECEx, etc.) for hazardous area installations.
