The 330173-00-04-20-12-05 is a 3300 series 5 mm proximity transducer probe featuring an M8×1 threaded body with 0 mm unthreaded length, a 40 mm case length, and a 2.0-meter total cable length. 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 measures both static (position) and dynamic (vibration) data. It functions in vibration and position measurement applications on fluid-film bearing machines, as well as Keyphasor measurement and speed measurement applications.
3300 5 mm probe
3300 XL extension cable (ref 141194-01)
3300 XL Proximitor Sensor (ref 141194-01)
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.This specific configuration improves upon older non-contacting sensor hardware. A patented TipLoc molding method provides a more robust bond between the probe tip and the probe body.
Crucially, the -12-05 configuration incorporates the FluidLoc cable option, which physically blocks oil and other process liquids from leaking out of the machine housing through the cable’s interior. Furthermore, the -05 option certifies the hardware with Multiple Agency Approvals, allowing safe deployment and compliance within hazardous, explosion-prone industrial environments.

Oil & Gas Refining
Tracks shaft dynamic displacement within fluid-film bearings to detect early impeller unbalance or fluid-induced instability.
Thermal Power Generation
Provides a once-per-turn voltage pulse to calculate exact rotor shaft speed and establish phase angles for dynamic balancing analysis.
Gas Turbine Power Plants
Captures sub-micron oil-film journal instabilities under high-temperature environments, using hazardous area ratings to ensure safe operation.
Hydroelectric Power Plants
Pairs two orthogonal probes (X-Y arrangement) to map the actual physical path of the shaft journal within the bearing, detecting hydraulic unbalance or misalignment.
Steel & Metallurgy Production
Detects shaft eccentricity and bearing wear caused by massive, variable thermal loads and high mechanical stresses inside the blower drive train.
Pulp & Paper Mills
Continuously measures internal shaft-to-bearing clearance variations amid high moisture, steam, and constant machine vibration.
When using the Bently Nevada 330173-00-04-20-12-05 probe, you must maintain a strict 5.0-meter total system electrical length by pairing its 2.0-meter integral cable with a 3.0-meter extension cable to prevent signal distortion. Ensure precise mechanical gapping (typically -10V DC bias voltage mid-range) relative to the AISI 4140 steel target surface during installation, and avoid exceeding the 4.5 N·m maximum tightening torque to protect the unarmored M8 threads from stripping. Finally, properly torque the Miniature ClickLoc connector, verify the intrinsic safety barrier connection for hazardous areas, and inspect the FluidLoc cable jacket to ensure its liquid-blocking properties remain intact.
The Bently Nevada 330173-00-04-20-12-05 is a 5mm industrial-grade non-contact eddy current proximity probe developed for axis vibration, axial displacement, and speed (Keyphasor) measurement of rotating machinery. This model configuration includes a fully threaded M8×1 case with zero unthreaded length, a 2.0-meter integral cable, an oil-impermeable FluidLoc shielded cable, and a miniature ClickLoc coaxial connector. Featuring a compact physical envelope, it is ideally configured for tight installation spaces inside fluid-film bearings. With high-fidelity signal transmission capabilities and multiple international explosion-proof certifications, this probe ensures high-accuracy asset condition monitoring in harsh industrial environments such as steam turbines and compressors.
It is a 3300 Series 5mm proximity probe manufactured by Bently Nevada, featuring an unarmored metric M8×1 threaded case, used for non-contact condition monitoring of industrial rotating machinery.
How do you use the 330173-00-04-20-12-05 probe?
You thread it into a machine casing or bracket close to a spinning shaft, connect it to an extension cable, and link it to a Proximitor Sensor to output a voltage gap signal.
What critical machinery does 330173-00-04-20-12-05 monitor?
It monitors high-speed rotating assets including steam/gas turbines, centrifugal compressors, gearboxes, and large industrial pumps.
