The Bently Nevada 330101-00-18-10-02-05, also cataloged as the 330101 Proximity Sensors, operates as a dedicated hardware component for non-contact relative shaft position and dynamic vibration measurement within 3300 XL Transducer System platforms. It generates an high-frequency eddy-current magnetic field at the probe tip to track mechanical target displacement relative to the machine bearing casing.

Eddy-Current Probe Scaling & Rotor Dynamics

The 330101-00-18-10-02-05 probe functions in conjunction with an extension cable and 3300 XL Proximitor sensor to provide standardized eddy-current probe scaling at a linear sensitivity of 7.87 V/mm (200 mV/mil). During physical setup, performing gap voltage validation targeting -10 VDC at nominal shaft centerline ensures maximum linear range for peak-to-peak dynamic displacement excursions. This continuous baseline measurement optimizes cross-talk suppression between adjacent orthogonal probe pairs monitored in rotor dynamics analysis.

Frequently Asked Questions

Q: What physical feature distinguishes the ClickLoc connector design?

A: The ClickLoc miniature coaxial connector incorporates a mechanical locking latch mechanism that prevents accidental disconnects and maintains low electrical resistance under machine vibration.

Q: How does option -05 affect installation requirements in hazardous locations?

A: The -05 option certifies the probe for CSA, ATEX, and IECEx intrinsic safety standards, requiring installation via certified intrinsic safety barriers or galavanic isolators per hazardous region codes.

Q: Can this 1.0-meter probe cable connect directly to a 5.0-meter Proximitor sensor without an extension cable?

A: No, the 1.0-meter probe requires a matching 4.0-meter extension cable to complete the total 5.0-meter electrical length required for accurate Proximitor calibration.

Field Installation Guidelines

  1. Inspect the 3/8-24 UNF threaded mounting bore to ensure it is clean and free of metal burrs.
  2. Thread the 1.8-inch case body into the mounting port by hand until the tip approaches the target shaft face.
  3. Power the associated 3300 XL Proximitor sensor and monitor the DC voltage output; adjust probe depth to achieve the target -10 VDC gap voltage baseline.
  4. Secure the probe position by tightening the external locknut against the mounting surface without imparting torsional stress to the coaxial lead.
  5. Connect the ClickLoc miniature coaxial connector to the extension cable and install protective insulating boots over the junction to isolate the shield from ground loop noise.
