Features:

  • Advanced Narrow Side-view Geometry for Spatial Constraint Optimization
  • Heavy-Duty TipLoc™ & CableLoc™ Mechanical Integrity Architecture
  • Gold-Plated ClickLoc™ Connection with Vibration-Proof Engagement
The Bently Nevada 330901-00-08-10-02-CN features an optimized NSv tip profile designed to prevent electromagnetic side-wall interference. Unlike standard 8mm probes, it operates reliably near counterbores down to 9.5 mm and keeps structural crosstalk to a minimum. This feature enables accurate radial vibration capture on very confined, narrow machinery components.

Built with patented co-molding technology, the Bently Nevada 330901-00-08-10-02-CN forms a secure bond between its PPS tip and stainless steel body to block moisture and chemical ingress. The cable assembly handles pull forces up to 220 N (50 lb). This rugged design prevents premature failure from severe turbulence, case expansion, or accidental handling during maintenance.

The Bently Nevada 330901-00-08-10-02-CN comes equipped with gold-plated brass coaxial ClickLoc™ connectors that snap securely into place. This design prevents signal drops and impedance shifts caused by high-frequency machine vibrations. It maintains low contact resistance and provides dependable, tool-free connectivity throughout long maintenance cycles.

The 330901-00-08-10-02-CN Bently Nevada 3300 XL NSv Proximity Transducer Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Centrifugal Air Compressor Machinery: The probe is widely used to track high-speed rotor dynamics in centrifugal air compressors. Its narrow side-view field profile allows it to operate without interference from internal structural counterbores, delivering steady radial vibration data.
  • Industrial Refrigeration Compressors: It is well-suited for confined chiller and refrigeration compressor housings. The chemical-resistant PPS tip withstands exposure to harsh synthetic oils and refrigerants.
  • Process Gas Turbomachinery: It plays a key role in tracking shaft motion inside gas-processing expanders and downscaled turbines, where restricted clearances make standard-sized 8mm eddy current sensors impractical.
  • Small-Diameter Shaft Applications: The system is optimized for precision monitoring on shafts smaller than 51 mm (2.0 in). This makes it an ideal choice for localized auxiliary pumps, blowers, and high-speed pilot plant machinery.
  • Radial Vibration & Position Capture: It tracks dynamic shaft orbit paths and fluid-film bearing clearances. The high-frequency response ensures early detection of oil whirl, unbalance, and rotor rub conditions.
  • Axial (Thrust) Displacement Tracking: It provides early warning of thrust bearing wear by monitoring small flat targets down to 15 mm (0.6 in). This measurement helps protect machine internals from catastrophic axial contact.
  • Phase Reference & Keyphasor® Provision: It delivers precise phase timing markers and zero-speed indicators. This data is essential for vector analysis, balancing routines, and tracking speed thresholds during startup and shutdown cycles.
  • Machinery Protection System Integration: The raw analog outputs connect to processing monitors to drive automated alarm and trip functions. This integration provides a fast safety shutdown path for critical industrial assets.
  • NEPSI & Regional Explosion Protection: The specialized "-CN" model complies with regional hazardous area requirements, ensuring safe operation in volatile Zone 0, Zone 1, and Zone 2 gas environments.
  • ATEX / IECEx Intrinsically Safe Compliance: It meets European ATEX directives and global IECEx standards for explosion protection. When connected to approved intrinsic safety barriers, it is certified for Class I, Division 1 and Zone 0 hazard zones.
  • Functional Safety (SIL 2 / SIL 3 Rated): The design complies with systematic IEC 61508 safety standards, supporting Hardware Fault Tolerance configurations up to SIL 2 (HFT=0) or SIL 3 (HFT=1). This allows for direct use in safety instrumented functions.
  • CE Mark & Industrial EMC Directives: The system meets EN 61000-6-2 and EN 61000-6-4 standards, offering high immunity to radio frequency (RFI) and electromagnetic (EMI) noise. This ensures stable signal quality even when installed near high-power industrial motor drives.

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.
What is the accurate internal impedance signature required to verify the health of a Bently Nevada 330901-00-08-10-02-CN probe during troubleshooting?
To diagnose the Bently Nevada 330901-00-08-10-02-CN, you should measure the DC resistance between the center conductor and the outer shield of the ClickLoc™ connector. Because this specific probe features a 1.0-meter total cable length, the nominal baseline resistance must fall precisely within the range of 4.2±0.5Ω. Any reading significantly higher indicates an open circuit or cable degradation, while a near-zero ohm value points to a short circuit within the probe tip or coaxial line.
Does the Bently Nevada 330901-00-08-10-02-CN support direct integration with third-party Modbus or Ethernet/IP PLCs, and how is the dynamic signal processed?
No, the Bently Nevada 330901-00-08-10-02-CN is an analog eddy-current sensor that cannot communicate directly via digital network protocols. It must interface with a 3300 XL NSv Proximitor® Sensor. The Proximitor demodulates the high-frequency RF signal into an analog voltage output at 7.87 V/mm (200 mV/mil). This output is routed to machinery monitors like the Bently Nevada 3500 series, which process the raw waveform data and can transfer register data to third-party DCS or PLCs via Modbus or communications gateways.
What are the specific terminal wiring constraints and cross-talk parameters when installing multiple Bently Nevada 330901-00-08-10-02-CN probes in an X-Y configuration?
When installing two Bently Nevada 330901-00-08-10-02-CN probes in an X-Y radial vibration layout, proximity to small shaft targets can cause electromagnetic cross-talk. If the probes are mounted in parallel, their tips must maintain a minimum physical separation of at least 25 mm (1.0 in). For standard 90-degree orthogonal configurations, you can minimize cross-talk by offsetting the probe centerlines axially along the shaft by at least 23 mm (0.9 in) to keep scale factor distortion under 10%.
How does target material composition alter the calibration and diagnostic depth of the Bently Nevada 330901-00-08-10-02-CN transducer system?
The Bently Nevada 330901-00-08-10-02-CN system comes factory-calibrated to standard AISI 4140 magnetic steel. If the probe is targeted against other metals, such as K-Monel, Inconel, or various stainless steel grades, the magnetic permeability and electrical conductivity shifts will alter the system's Incremental Scale Factor (ISF). Integrating the probe with non-4140 targets requires a custom calibration curve or a specialized Proximitor to prevent major amplitude measurement errors.
What is the proper mechanical installation procedure and maximum case torque rating for the Bently Nevada 330901-00-08-10-02-CN probe?
When threading the Bently Nevada 330901-00-08-10-02-CN into a 1/4-28 UNF tapped hole, you should first check that the unthreaded length is correct. The absolute maximum torque limit for this 1/4-inch case size is 7.3 N·m (65 in·lb); exceeding this value can twist the probe housing or damage the internal coaxial joints. It is highly recommended to tighten the probe to a operational torque of 5.1 N·m (45 in·lb). The coaxial ClickLoc connectors should be joined finger-tight.
What hazardous area approvals are covered by the "-CN" designation on the Bently Nevada 330901-00-08-10-02-CN, and what are its global safe-use conditions?
The "-CN" option code for the Bently Nevada 330901-00-08-10-02-CN indicates regional hazardous area compliance, primarily matching Chinese NEPSI standards along with ATEX and IECEx certifications for Zone 0, Zone 1, and Zone 2 environments. When used in intrinsically safe "ia" configurations, the probe must be wired through approved galvanic isolators or Zener barriers according to Bently Nevada control drawings.
