Features:

  • Optimized for Tight Installation Geometries
  • Extreme Thermal Durability
  • Rugged Mechanical Interconnect
The Bently Nevada 330903-03-11-05-02-05 features an M8x1 thread and redesigned side-view characteristics, allowing installation in counterbores as small as 9.5 mm. It is the ideal solution for small shaft trains and fluid-film bearing machines where standard 8mm probes cannot be mounted due to physical interference.

Constructed with a PPS tip and AISI 304 SST case, this probe operates reliably in harsh environments ranging from -52°C to +177°C. The patented TiLoc molding method ensures a robust bond between the probe tip and body, preventing failures caused by thermal cycling or vibration in process gas and refrigeration compressors.

The Bently Nevada 330903-03-11-05-02-05 utilizes gold-plated brass ClickLoc connectors and the CableLoc design, providing 220 N (50 lb) of pull strength. This ensures the connection cannot loosen due to machinery vibration, providing a fail-safe signal path for critical protection systems.

The 330903-03-11-05-02-05 Bently Nevada 3300 NSv Proximity Probes may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
  • Features gold-plated brass miniature coaxial ClickLoc connectors, forming a fully interlocked connection with the probe, extension cable, and Proximitor sensor to prevent loosening due to vibration.
  • Provides the industry-standard output of 200 mV/mil (7.87 V/mm), allowing direct integration with Bently Nevada monitoring systems as well as third-party PLCs and DCS.
  • With a total length of 5 meters, this probe works with matching NSv extension cables to support 5m or 7m Proximitor sensor system lengths.
  • The Bently Nevada 330903-03-11-05-02-05 comes with standard cable configuration and no connector protector, making it suitable for tight internal machine installations where liquid contamination is not a concern.
  • The probe operates continuously from -52°C to +177°C, suitable for high-temperature turbine internals as well as low-temperature refrigeration compressors.
  • With connectors properly protected, the probe can withstand 100% condensing humidity environments, complying with IEC 68-2-3 damp heat testing.
  • Configured with "Multiple Approvals," this model supports Ex ia IIC T4/T5 Ga (Zone 0), Class I/II/III intrinsic safety, and non-incendive applications.
  • Features a Viton O-ring for differential pressure sealing at the probe tip and offers improved chemical resistance against process gases and aggressive media compared to 3300 RAM probes.
  • Designed for radial vibration measurement on centrifugal air compressors, refrigeration compressors, and process gas compressors with shaft diameters smaller than 51 mm, solving installation constraints where standard probes cannot fit.
  • Suitable for axial (thrust) position measurement on flat targets smaller than 15 mm (e.g., small thrust collars), ideal for compact machines with limited mounting space.
  • Can be used as a non-contact speed probe in small turbomachinery or gear drives, providing reliable Keyphasor reference signals.
  • Directly replaces 3300 RAM probes and offers a complete upgrade path from 3000/7000-series 190 probe systems without requiring internal casing modifications.
Description
The Bently Nevada 330903-03-11-05-02-05 is engineered specifically for centrifugal air compressors, refrigeration units, and process gas compressors where counterbore, side-view, or rear-view restrictions limit the use of standard 5mm and 8mm transducer systems. With its compact M8x1 thread and unarmored design, this probe excels in measuring radial vibration on shafts smaller than 51 mm (2 in) and axial position on flat targets smaller than 15 mm (0.6 in). It serves as a direct upgrade path for legacy 3300 RAM and 3000-series 190 transducer systems.

The Bently Nevada 330903-03-11-05-02-05 features a total length of 5.0 meters and utilizes the industry-standard average scale factor of 7.87V/mm (200 mV/mil), ensuring seamless integration with existing monitoring networks. Despite its compact size, it offers a linear range of 1.5 mm (60 mils), which exceeds the range of the older 3000-series 190 systems. The probe tip is constructed from Polyphenylene sulfide (PPS) with a AISI 304 stainless steel case, rated for extreme operating temperatures from -52℃ to +177℃.

Technical notes
The Bently Nevada 330903-03-11-05-02-05 does not include a connector protector; for turbine oil environments, Bentley Nevada recommends using the accessory connector protectors or silicone tape (provided with extension cables, but not recommended for oil exposure).

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can the Bently Nevada 330903-03-11-05-02-05 be used to replace my existing 3300 RAM probe?
Yes. The Bently Nevada 330903-03-11-05-02-05 is mechanically and electrically compatible with 3300 RAM probes and extension cables. However, if you are upgrading from a 3000-series or 7000-series system, the probe, extension cable, and Proximitor sensor must all be replaced with NSv components.
Is the Bently Nevada 330903-03-11-05-02-05 safe for use in hydrogen compressors or high-humidity environments?
Absolutely. The Bently Nevada 330903-03-11-05-02-05 carries Multiple Approvals including Ex ia IIC T4/T5 Ga for Zone 0 explosive gas atmospheres. For humidity, it is tested to IEC 68-2-3 damp heat and rated for 100% condensing humidity (non-submersible) when connectors are properly protected.
The part number Bently Nevada 330903-03-11-05-02-05 ends in "02" for the connector. Do I need extra protection for the connection?
Since the Bently Nevada 330903-03-11-05-02-05 uses Option 02 (standard cable, no connector protector), you should purchase connector protectors (e.g., 40113-03) if the connection point will be exposed to turbine oil or condensation. Silicone tape is supplied with extension cables but is not recommended for turbine oil applications.
Will a small counterbore or nearby metal edge affect readings from the Bently Nevada 330903-03-11-05-02-05?
Yes. If the counterbore is smaller than 13 mm (0.5 in), the Bently Nevada 330903-03-11-05-02-05 may experience a scale factor shift at far gaps. Reducing the probe gap helps maintain Average Scale Factor over a reduced linear range. Keep the probe center at least 5.1 mm from any metal edge to avoid side-view interference.
Is the Bently Nevada 330903-03-11-05-02-05 compatible with the 3300 XL NSv Proximitor Sensor?
Yes. The Bently Nevada 330903-03-11-05-02-05 is specifically designed for use with the 3300 XL NSv Proximitor Sensor. When combined with the appropriate NSv extension cable, it forms a complete 3300 XL NSv transducer system for critical machinery protection.
