The Bently Nevada 330103-05-13-10-02-00, also cataloged as the 330103 Proximity Probe, operates as a dedicated hardware component for non-contacting shaft displacement and vibration measurements within 3300 XL Machinery Protection System configurations. This transducer conversion translates physical gap clearance variations into an electrical voltage directly proportional to static or dynamic movement. The sensor maintains physical separation from the observed target while acquiring fluid-film bearing performance indicators such as radial vibration and axial position.

Physical and Electrical Specifications

Eddy-Current Probe Scaling and Cross-Talk Suppression

The 8 mm eddy-current probe scaling is physically calibrated for AISI 4140 steel targets to deliver a predictable voltage response. For precise machine health integration, gap voltage validation requires centering the probe to register a -10 VDC targets reference voltage at the Proximitor output terminal. In multiple-sensor arrangements, cross-talk suppression is maintained by ensuring proper physical distance between probe tips and implementing shielding controls. This physical configuration prevents overlapping magnetic fields from degrading structural rotor dynamics measurements across the orthogonal X-Y radial measurement axes.

Package Contents

• 1 330103-05-13-10-02-00 Proximity Probe with 1.0 m integrated coaxial cable

• 2 M10 x 1 Hex Jam Nuts

• 1 Pre-installed Coaxial Connector Protector

Field Installation Guidelines

• Mechanical Alignment and Torque Limits

  • Thread the probe into the mounting bracket using a minimum of 5 full threads of engagement to secure the position.

  • Adjust the sensor body until the electrical gap voltage matches specification, then torque the locknuts to a maximum value of 5.1 N-m (45 in-lb).

• Conduit Routing and Shielding Rules

  • Bend radii along the coaxial cable must never drop below 25.4 mm (1.0 in) to prevent internal core layer fractures.

  • Route all probe lead wires within dedicated metal conduits separate from high-current AC cabling to maintain shield continuity.

Frequently Asked Questions

• What specific gap voltage must be set during initial physical setup?

  The hardware alignment must position the probe tip to register a baseline -10 VDC output from the Proximitor, matching the midpoint of the 80 mil linear window.

• Can this probe be connected to a receiver without using a Proximitor sensor?

  No, this is a passive eddy-current sensor that requires the matched RF drive and demodulation circuits of a 3300 XL Proximitor to produce a readable signal.

• Does this model option contain an external flexible stainless steel armor layer?

  No, the 330103-05-13-10-02-00 part number denotes a standard coaxial cable assembly without the optional flexible outer armor sheath.

• Is the system operation affected if the coaxial cable length is manually modified?

  Yes, cutting or splicing the cable alters the precise internal tuning capacitance, which directly shifts calibration parameters and corrupts the scale factor.

• What targets material must be monitored to ensure nominal linear scaling?

  The factory calibration profile is mapped to AISI 4140 steel; using alternative shaft metals changes the magnetic response and requires system recalibration.

• Is it permissible to connect or disconnect the probe while the system loop is live?

  Yes, hot-swap connections at the coaxial interface will not cause physical or electrical component failure, though a temporary channel fault state will log.

• How should the miniature ClickLoc coaxial connection be protected from ambient moisture?

  Apply the included connector protector cap or wrap the connection with self-fusing silicone tape to prevent moisture from introducing leakage resistance.

• What determines the length requirement of the external extension cable for this probe?

  Since this probe contains an integral 1.0 m lead, it must be paired with a matching 4.0 m or 8.0 m extension cable to achieve a total 5.0 m or 9.0 m system length.
