The Bently Nevada 330104-00-03-05-02-05, also cataloged as the 330104-00-03-05-02-05 Proximity Sensors, operates as a dedicated hardware component for non-contact shaft displacement measurement within 3300 XL vibration monitoring platforms.

Model Matrix

The 330104-00-03-05-02-05 configuration specifies a 3/8-24 UNF thread, a 30 mm unthreaded length, a 50 mm case length, and an overall system length of 0.5 meters, terminated with a miniature coaxial ClickLoc connector.

Hardware Specifications

Transducer Signal Dynamics

The probe utilizes eddy-current induction to generate a proportional voltage output based on the proximity of a conductive target. Proper scaling requires an unloaded gap voltage target of approximately -10 VDC within the 0.25 mm to 2.3 mm linear range. Rotor dynamics analysis depends on consistent probe excitation; cross-talk suppression is maintained through standardized coaxial shielding and the use of approved Bently Nevada 330130 extension cables. System linearity must be verified against the calibrated Proximitor sensor curve to ensure accurate peak-to-peak vibration amplitude detection.

Ordering Info

• Included: Probe assembly with two stainless steel jam nuts.

• Accessory: Requires compatible 330130 series extension cable.

• Accessory: Requires 3300 XL Proximitor sensor for signal conditioning.

• Cable Routing: Install in grounded rigid conduit; avoid proximity to high-voltage AC or variable frequency drive (VFD) cabling.

• Connector Integrity: Ensure the ClickLoc coupling is tightened to prevent impedance variation at the interface.

Logistics and Transit

• Delivery time: 2-7 days when payment finish.

• Shipment: Distributed via DHL/FEDEX/UPS.

• Handling: Components are sealed in anti-static industrial packaging to prevent electrostatic discharge and mechanical impact during transit.

Technical FAQ

• What material targets are supported?

  Supported targets are AISI 4140 steel or equivalent ferromagnetic materials with high magnetic permeability.

• What is the probe sensitivity?

  The system provides a standardized output of 7.87 V/mm (200 mV/mil).

• How often should calibration be verified?

  Calibration verification is suggested during major machine outages or if the gap voltage drifts outside the specified nominal operating range.

• Can the probe operate in hazardous environments?

  Operation in hazardous areas is restricted to the specifications provided in the agency approval documentation for the specific -05 suffix.

• What causes unstable gap voltage?

  Instability is typically induced by ground loops, damaged coaxial cable shielding, or mechanical looseness in the probe mounting bracket.

• How is probe health tested?

  Health is assessed by conducting a static gap calibration test and verifying the voltage output against a known physical distance to a target.

• What is the expected service life?

  Under clean oil environments within thermal ratings, the component supports continuous operation exceeding 10 years.
