The 330171-00-12-50-01-CN is a 3300 series 5 mm sensor featuring a 1/4-28 English thread, 0 mm unthreaded length, and a 1.2-inch overall case length. This specific hardware configuration includes a 5.0-meter total integral cable equipped with a miniature coaxial ClickLoc™ connector and connector protector, complete with China-specific hazardous area agency approvals (-CN) for reliable machinery condition monitoring in explosive environments.
Enhanced Sideview Characteristics
Small Target Performance
TipLoc & CableLoc Technology
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 [3300 5mm Datasheet]. 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 . The 3300 5 mm probe improves upon previous designs. A patented TipLoc molding method provides a more robust bond between the probe tip and the probe body. The 3300 5 mm system is orderable with Fluidloc cable options for preventing oil and other liquids from leaking out of the machine through the cable’s interior.

Petrochemical & Oil Refining
Monitoring the fluid-film bearing shaft vibration of small-to-medium high-speed multistage centrifugal pumps in high-risk zones, utilizing the -CN certification to ensure intrinsic safety in explosive hazardous areas.
Coal-to-Liquids & Coal Chemical Industry
Used for online journal rotor displacement monitoring of small-to-medium high-pressure slag valve hydraulic drive pumps in coal gasification plants, preventing sudden jamming from triggering system interlocking shutdowns.
Fine Chemicals & Pharmaceuticals
Monitoring the radial runout of the cantilever shafts of high-value distillation tower high-speed reactor agitators, where the 5 mm probe tip perfectly fits highly restricted mounting walls constrained by mechanical seals.
Iron, Steel & Non-Ferrous Metallurgy
Used for online condition monitoring of fluid-film bearings in high-temperature industrial blowers, a core equipment of steel rolling mill furnace air supply systems, utilizing the stainless steel armor to resist splashing steel slag or metal debris.
Cement & Building Materials Manufacturing
Used for real-time journal dynamic runout monitoring of fluid-film bearings in high-power exhaust circulation pumps at the tail of clinker rotary kilns, preventing bearing pad burnout caused by excessive eccentricity.
When using the 330171-00-12-50-01-CN, special attention must be paid to parameter matching and hardware protection. It features a 5.0-meter integral cable and must be connected directly to a 5-meter 3300 XL Proximitor without any additional extension cables to prevent signal distortion.
Since the 5 mm probe tip is small, its linear range is limited to 2.0 mm, making it critical to strictly adjust the initial gap voltage near the linear midpoint (typically around -10V DC) using a multimeter during cold-state installation to avoid out-of-range readings.
Furthermore, the factory-supplied connector protector must be correctly installed to completely isolate the ClickLoc coaxial connector from oil and moisture, and proper cable grounding must be secured to comply with domestic (-CN) hazardous area regulations.
The Bently Nevada 330171-00-12-50-01-CN is a 1/4-28 threaded 3300 series 5 mm proximity probe with a 1.2-inch case and 5.0-meter cable. Supporting 2.0 mm linear measurement and 7.87 V/mm sensitivity, this hardware integrates TipLoc and CableLoc technologies. With China approvals (-CN), it connects directly to a Proximitor sensor for vibration, Keyphasor, and speed monitoring in hazardous environments.
It is a Bently Nevada 3300 series 5 mm English threaded non-contact eddy current proximity probe, used to measure shaft vibration, Keyphasor reference, and speed of rotating machinery in restricted spaces.
What are the thread specifications and case length of 330171-00-12-50-01-CN?
This model is configured with a 1/4-28 UNF English fully threaded case, an unthreaded length of 0 mm, and an overall case length of 1.2 inches (approximately 30 mm).
What is the basic measurement mechanism of 330171-00-12-50-01-CN?
The coil at the probe tip generates an alternating magnetic field that induces eddy current losses on the target metal surface, precisely converting the distance by monitoring changes in electromagnetic impedance.
What is the linear measurement range of 330171-00-12-50-01-CN?
Although its hardware tip is only 5 mm, it still provides a standard 2.0 mm (80 mils) full-scale linear measurement range.
What is the voltage output sensitivity of 330171-00-12-50-01-CN?
When integrated into the system with its matching Proximitor sensor, its standard dynamic output gain sensitivity is strictly maintained at 7.87 V/mm (200 mV/mil).
