Bently Nevada 330104-00-02-10-02-05

roduct Introduction
The Bently Nevada 3300 XL series 8 mm proximity probes are high-precision, non-contact eddy current sensors engineered for the measurement of shaft vibration, axial (thrust) position, Keyphasor reference, and speed (RPM) in industrial rotating machinery. These probes are part of the comprehensive 3300 XL Proximity Transducer System, which includes the probe, extension cable, and proximitor, designed to provide reliable, high-resolution monitoring for critical equipment.

Description

Bently Nevada 330104-00-02-10-02-05

  • Technical Specifications:
    • Unthreaded Length: 0 mm
    • Overall Case Length: 20 mm
    • Total Length: 1.0 m
    • Thread: M10 × 1 mm
    • Connector: Miniature coaxial ClickLoc, standard cable
    • Approvals: CSA, ATEX, IECEx (Option 05)
    • Linear Range: 2.0 mm (80 mils)
    • Scale Factor: 7.87 V/mm
  • Functional Features: Integral SST armor protects cable from abrasion; gold-plated ClickLoc connector; fully interchangeable with 3300 XL extension cables and Proximitors without bench calibration; HazLoc certified for Zone 0/Div 1 with barriers.
  • Application Scenarios: Steam turbine bearing vibration, compressor shaft orbit, pump radial motion in petrochemical plants and offshore platforms.
  • Performance Parameters: Frequency response 0 to 10 kHz (±3 dB with proper Proximitor); probe DC resistance ~7.59 Ω at 1.0 m; output impedance 50 Ω; supply −17.5 to −26 Vdc.
  • Material Composition: Tip PPS; case 303/304 SST; armor 302 SST with FEP jacket; Viton O-ring pressure seal; gold-plated beryllium-copper center contact.
  • Structural Features: Forward-mount probe, 8 mm OD tip, M10 hex flats, 20 mm total case length including 15 mm max thread zone, 1.0 m armored lead, ClickLoc male.
  • Working Principle: RF oscillation from Proximitor excites coil; eddy currents induced in target shift coil impedance proportionally to gap; Proximitor converts impedance to dc voltage (−1 to −17 Vdc).
  • Installation Requirements: Thread into machined M10×1 boss, torque 7.5 N·m typical (max 11.2 N·m), engage ≤15 mm; set gap to −9 Vdc using gap tool; finger-tight ClickLoc to extension cable; min bend radius 25.4 mm.
  • Usage Precautions: Do not exceed 15 mm thread engagement; never use pliers on ClickLoc; below −34 °C risk to Viton seal; 1 m probe must pair with 1 m-class system (not 5 m Proximitor).
