Bently 330910‑00‑14‑10‑02‑00

Product Introduction: The 330910‑00‑14‑10‑02‑00 is a member of 3300 NSv compact proximity probe product line. It adopts 1.4‑inch unthreaded tip dimension, 1.0‑inch case length, factory pre‑assembled 10‑meter triaxial cable and ClickLoc miniature coaxial connector. This eddy‑current probe is engineered for shaft vibration, thrust displacement and rotational speed measurement under restricted installation space. It matches 3300 NSv proximitor modules and 990/991 NSv two‑wire transmitters. Hermetically sealed probe body tolerates high temperature, machine‑oil immersion and sustained mechanical vibration in turbomachinery bearing cavities. It satisfies API‑670 specification for critical rotating machinery protection.

  1. Optimized 1.4‑inch unthreaded tip dimension, balances installation compactness and effective linear sensing performance.
  2. Laser‑welded full hermetic sealing structure blocks ingress of oil, water and process vapor into internal coil chamber.
  3. Finger‑operated ClickLoc locking connector eliminates screw‑tightening work, resists loosening under long‑time operational vibration.
  4. Complete factory assembled 10‑meter triaxial cable preserves calibrated electrical length of whole NSv transducer chain.
  5. Direct compatibility with NSv‑standard proximitor hardware and DIN‑rail NSv transmitters, no field calibration adjustment.
  6. Excellent thermal stability, measurement deviation stays minimal across wide operating temperature span.
  7. Suitable for multiple target material, delivers stable output for carbon‑steel rotating shaft targets. Application Scenarios: Radial vibration measurement for compressors, steam turbines and large process pumps; axial thrust‑position monitoring in compact bearing housings; key‑phasor rotational speed pickup; machinery upgrade reconstruction with narrow mounting space; power generation and petrochemical plant critical equipment protection loops. Performance Parameters: Linear error ≤ ±0.5% full‑scale; low inherent electrical noise; phase shift ≤5° inside working frequency band; long‑term operational stability without frequent recalibration. Material Composition: AISI 316 stainless‑steel probe housing and threaded fitting; precision‑wound copper sensing coil; high‑temperature ceramic insulating core; FEP‑jacketed triaxial signal cable; gold‑plated coaxial contact assemblies; fluorosilicone high‑temperature sealing gaskets; laser‑welded metal sealing seams. Structural Characteristics: Compact cylindrical probe tip; 1/4‑28 UNF external mounting thread; rear permanently potted triaxial cable assembly; cable‑end ClickLoc miniature coaxial plug; model number and unique serial identifier laser‑etched onto probe outer metal surface. Working Principle: High‑frequency excitation signal from matched proximitor feeds probe internal coil, generating alternating magnetic field at probe tip. Magnetic field penetrates air gap and induces eddy current on conductive shaft surface. Variation of physical gap distance changes eddy‑current intensity and coil impedance. Proximitor circuit converts impedance fluctuation into DC gap‑voltage plus superimposed dynamic AC vibration signal. Gap‑voltage magnitude maintains linear correlation with tip‑to‑target clearance. Installation Requirements:
  8. Thoroughly clean mounting threaded hole, remove burr, rust and residual sealant to guarantee full‑thread engagement.
  9. Apply manufacturer‑specified torque for probe fastening; over‑torque produces permanent damage to internal coil assembly.
  10. Adjust static working gap between probe tip and shaft target to sit in middle zone of probe linear range.
  11. Keep enough physical separation between adjacent probe tips to prevent electromagnetic cross‑talk disturbance.
  12. Triaxial signal cable minimum bending radius must be greater than ten times cable outer diameter, sharp folds and squeezing are forbidden.
  13. Separate probe signal routing from high‑power motor and variable‑frequency drive cables to reduce electromagnetic interference.
  14. Tighten ClickLoc connector only by finger force; excessive torque damages gold‑plated internal contacts. Usage Notes:
  15. Probe housing cannot be opened, breaking laser‑welded hermetic seal will invalidate factory calibration and environmental resistance.
  16. Cutting or splicing factory‑integrated triaxial cable is prohibited, modified electrical length ruins measurement linearity and sensitivity.
  17. Avoid heavy impact and scratching on probe‑tip ceramic surface, surface scratch degrades sensing accuracy.
  18. Prevent cable from sustained contact with high‑temperature process piping to avoid accelerated jacket material aging.
  19. Check probe mounting tightness and connector locking condition in every equipment overhaul cycle.
