Description

The 330902-04-48-10-02-00 is a 3300 NSv Proximity Probe with 1/4-28 UNF thread and armor, designed as a component of the 3300XL NSv Proximity Transducer System from Bently Nevada. The 330902-04-48-10-02-00 is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements where counter bore, side-view, or rear-view restrictions limit the use of standard Bently Nevada 3300 and 3300XL 5mm and 8mm transducer systems.

The 330902-04-48-10-02-00 is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51mm (2in) or axial position on flat targets smaller than 15mm (0.6in). The 330902 is primarily used for radial vibration and radial position measurements, axial (thrust) position measurements, tachometer and zero speed measurements, and phase reference (Keyphasor signals) on fluid-filmed bearing machines where a small shaft or reduced side-view is present.

Features:

  • 1/4-28 UNF threaded mounting

  • Enhanced side-view and small target characteristics
  • Patented TipLoc molding method
The Bently Nevada 330902-04-48-10-02-00 is a member of the 3300 NSv Proximity Probe family, developed for machinery monitoring applications where installation space is limited and standard 8 mm proximity probe systems cannot be accommodated. The probe uses eddy current sensing technology to provide non-contact measurement of shaft displacement, shaft vibration, eccentricity, and rotor position in rotating machinery.

The probe features a 1/4-28 UNF-2A threaded case for mounting into probe holders or brackets in confined spaces. The case is constructed from AISI 303 or 304 stainless steel, with a 5.0 mm diameter polyphenylene sulfide (PPS) probe tip. The overall case length is 48 mm. The probe tip is non-metallic and electrically insulated from the case, preventing electrical interference and allowing direct contact with conductive shaft surfaces without short-circuiting the eddy current field.

The 330902-04-48-10-02-00 Bently Nevada 3300 NSv Probe, 1/4-28 UNF thread,with armor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The probe operates on the eddy current principle, generating a high-frequency electromagnetic field that induces eddy currents in a conductive target surface. The resulting impedance change is measured by the companion 3300 NSv Proximitor Sensor (330980 series), producing a DC voltage output proportional to the gap between the probe tip and the target surface. The system provides both static (position) and dynamic (vibration) measurement capability.
  • Steam & Gas Turbines:High-speed rotor dynamics & structural shifts
  • Centrifugal & Axial Compressors:Shaft imbalances & aerodynamic thrust surges
  • Generators & Gearboxes:Early warning to prevent catastrophic failures
  • Power Generation:Turbines, generators & exciter shafts: vibration/eccentricity
  • Oil & Gas / Petrochemical:High-speed centrifugal, process gas compressors & turboexpanders
  • Water & Waste Treatment:Multi-stage pumps & cooling tower fans

Target Material: The factory standard calibration matches AISI 4140 steel. Alternative target materials require custom factory recalibration.
Gap Voltage Target: Mechanically adjust the probe until the Proximitor sensor measures -10.0 Vdc at the signal output. This sets it precisely at the midpoint of its 1.5 mm linear range.
System Match: Pair the 1.0-meter probe with a matching 4.0-meter extension cable. This builds the mandatory 5.0-meter total electrical system length required by the Proximitor sensor.

Technical notes

The 330902-04-48-10-02-00has an Average Scale Factor of 7.87V/mm (200mV/mil), which is the most common output for eddy current transducers. The 330902-04-48-10-02-00 features enhanced side-view and small target characteristics that give it a shorter linear range than the Bently Nevada 3300XL-series 5mm and 8mm transducer system, with 1.5mm (60mils) of linear range that exceeds the linear range of the 3000-series 190 transducer system.

FAQs

  • What is the 330902-04-48-10-02-00?

    +
    The Bently Nevada 330902 is an 3300 NSv Probe, 1/4-28 UNF thread,with armor from the 3300 NSv (Non-Standard velocity) series.
  • What is the 3300 NSv series primarily used for?

    +
    The 3300 NSv proximity system is typically used for measuring vibration and position on smaller rotating machines or in applications where a standard 8mm probe lacks the required clearance or target area.
  • What is the difference between armored and standard cable options?

    +
    Armored probes (often denoted by the -05 connector/cable option) feature braided stainless steel protection around the coaxial cable. This is highly recommended for environments with severe mechanical wear, abrasion, or harsh cable tray installations. Standard cables lack this armor but are suitable for protected cable routing.
  • What are the torque specifications for installing the probe?

    +
    For the standard 1/4-28 thread probe, the recommended torque is 5.1 N⋅m (45 in⋅lb). The maximum torque is 7.3 N⋅m (65 in⋅lb) to prevent damaging the threads or the probe body.
