Bently Nevada 330104-00-24-10-02-00 3300 XL 8 mm Proximity Probe

The Bently Nevada 330104-00-24-10-02-00, also cataloged as the 330104 proximity probe, serves as the primary 8 mm eddy‑current sensing element used to execute shaft‑vibration and rotor‑position measurements across 3300 XL monitoring platforms. This configuration implements a 0 mm unthreaded length, 240 mm case length, 1.0 m system length, and a miniature coaxial ClickLoc connector with FluidLoc cable protection.

Hardware Specifications

Eddy‑Current Scaling and Rotor‑Dynamic Measurement Behavior

3300 XL probes follow a standardized eddy‑current scaling curve that ensures consistent displacement interpretation across the 8 mm measurement range. The proximitor drives the probe toward a nominal −10 VDC gap‑voltage target, establishing linear response for rotor‑dynamic tracking. The extended 240 mm case length supports installations requiring deeper mechanical reach into bearing housings or brackets. The ClickLoc connector maintains coaxial shielding continuity, while the FluidLoc cable design reduces contamination ingress and preserves impedance stability. These characteristics suppress cross‑talk and micro‑motion noise in multi‑probe configurations.

Frequently Asked Questions

Q: Can the probe be replaced while the proximitor is energized? A: No. Replacement should only occur with the channel de‑energized to avoid transient gap‑voltage excursions.

Q: Does modifying cable length affect calibration? A: Yes. System length is factory‑matched. Any non‑standard extension alters impedance and shifts the scaling curve.

Q: Is firmware required for probe compatibility? A: No. The probe contains no firmware. Compatibility is determined solely by proximitor and monitor configuration.

Field Installation Guidelines

Ensure the threaded M10 × 1 case is seated cleanly in a burr‑free mounting bore. Maintain proper standoff distance before verifying gap voltage. Route coaxial cable away from high‑current conductors to minimize induced noise. Bond shielding at the proximitor end only to prevent ground loops. Avoid sharp cable bends that may alter impedance. Confirm ClickLoc connector engagement before commissioning.
