Features:

  • Compact 8 Mm NSv Probe Provides Accurate Shaft Displacement And Vibration Measurements.
  • Stainless Steel Case With PPS Tip Ensures Durable Operation In Harsh Environments.
  • Miniature Coaxial ClickLoc Connector With Standard Cable Delivers Reliable Signal Transmission.
The Bently Nevada 330905-00-12-05-02-RU 3300 NSv Probe is designed for precise, non-contact monitoring of rotating machinery, particularly in applications with limited installation space. Its compact 120 mm case and short 0.5-meter cable allow easy placement in confined areas while maintaining high measurement accuracy.

Engineered for durability, the probe features a stainless steel body with a PPS tip to resist wear, chemical exposure, and mechanical stress. The system provides a nominal DC resistance of 4.0 ± 0.5 Ω and an output voltage of 0.002 mil pp/gauss, ensuring consistent data quality for both static shaft position and dynamic vibration monitoring.

When integrated with 3300 NSv extension cables and the XL NSv Proximitor Sensor, this probe forms a complete transducer system capable of providing vibration, displacement, and Keyphasor reference signals. Its robust construction, precise electrical characteristics, and compact design make it ideal for continuous monitoring and predictive maintenance of critical compressors and similar rotating equipment.

The 330905-00-12-05-02-RU Bently Nevada 3300 NSv Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer GE / Bently Nevada
  • Model 330905-00-12-05-02-RU
  • Condition New Original ready stock
  • Product Family 330905-00-40-05-02-05,330905-00-30-05-02-00,330905-00-25-05-02-05
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Extreme Temperature Range: The probe head can operate stably in environments ranging from -35°C to +177°C (-31°F to +350°F).
  • High-Pressure Sealing Environment: The probe tip is designed with an airtight seal between itself and the housing, capable of withstanding oil and air pressure within the bearing housing.
  • Chemical Corrosion Resistance: Utilizing a polyphenylene sulfide (PPS) probe tip, it exhibits strong resistance to industrial lubricants, synthetic oils, and most solvents.
  • Leak-Proof Design: Equipped with FluidLoc (02) liquid-resistant cable, effectively preventing process fluids or lubricants from leaking into the junction box through the cable core.
  • Regional Access Standards: With RU (GOST) certification, it meets the high-altitude and explosion-proof access requirements of Russia and the CIS countries.
  • Small Target Measurement: The NSv (Narrow Side view) is specifically designed for monitoring shafts or narrow observation surfaces with a diameter less than 9.5 mm (0.375 in). Compact Space Monitoring: The probe housing has only 1/4-28 thread, suitable for extremely small gaps or precision machinery where large probes cannot be installed.
  • Linearity Feedback: With the NSv preamplifier, it provides a standard 7.87 V/mm (200 mV/mil) voltage output, accurately reflecting the dynamic displacement of the shaft.
  • System Self-Check (OK Circuit): The monitoring system monitors cable integrity in real time, and immediately triggers an OK relay alarm in the event of an open circuit or short circuit.
  • Small Industrial Units: Widely used for shaft vibration monitoring in small centrifugal compressors, industrial fans, and centrifugal pumps.
  • Auxiliary Mechanical Protection: Used for remote online monitoring of "non-critical but important" equipment such as lubricating oil pumps and cooling tower fans.
  • Slot/Deep Hole Mounting: Due to its 120mm (12) housing length and small diameter, it is often used in special bearing housings that require passing through narrow mounting holes.
  • Gearbox Monitoring: Monitors the radial runout of gear shafts inside space-constrained gearboxes. Deployment in high-altitude and cold regions: RU certification makes it the designated protection sensor for small rotating equipment in energy transmission pipelines in Siberia or Central Asia.
Description
The Bently Nevada 330905-00-12-05-02-RU 3300 NSv Probe is part of the 3300 NSv Proximity Transducer System, engineered for use in centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines where space is limited. Its compact design, with an overall case length of 120 mm and zero minimum unthreaded length, allows flexible mounting in tight machinery configurations.

Constructed from AISI 304 stainless steel with a polyphenylene sulfide (PPS) probe tip, the 330905-00-12-05-02-RU offers durable operation under industrial conditions. The standard cable connects via a miniature coaxial ClickLoc connector to ensure reliable signal transmission. With a nominal DC resistance of 4.0 ± 0.5 Ω and an output voltage of 0.002 mil pp/gauss, the probe delivers accurate, consistent measurements for both static position and dynamic vibration.

The probe forms a complete transducer system when paired with 3300 NSv extension cables and the 3300 XL NSv Proximitor Sensor. This combination provides precise vibration and displacement readings, supporting Keyphasor reference signals and enabling predictive maintenance for critical rotating equipment. Its compact dimensions, robust materials, and reliable electrical performance make it an ideal solution for continuous monitoring in space-constrained industrial applications.
