Bently Nevada 330102-00-33-05-02-00 Sensor Probe Cable

Configured for eddy‑current transducer signal routing in 3300 XL measurement chains, the Bently Nevada 330102-00-33-05-02-00 (330102 probe cable) provides direct physical/electrical execution of the coaxial link between an 8 mm proximity probe and its matching Proximitor sensor. The assembly maintains controlled impedance, defined mechanical geometry, and stable transmission characteristics across rotor‑dynamic monitoring paths.

Hardware Specifications

Eddy-Current Probe Scaling and Cross-Talk Suppression

The 330102 cable preserves the −10 VDC gap voltage scaling used across Bently Nevada proximity systems by maintaining the exact coaxial impedance required for linear displacement response. Its shielding geometry minimizes cross‑talk when routed alongside other transducer cables, ensuring clean rotor‑dynamic signatures. Mechanical stability of the cable prevents impedance drift caused by bending, vibration, or thermal cycling, maintaining consistent field behavior between the probe tip and Proximitor driver.

Frequently Asked Questions

Q: Must the cable length match the probe and Proximitor part numbers? A: Yes. Eddy‑current systems require exact cable length matching to maintain correct −10 VDC gap voltage calibration.

Q: Can the cable be routed through armored conduit? A: Yes, provided bend radius limits are respected to avoid deformation of the coaxial geometry.

Q: Does the cable support repeated ClickLoc connector cycles? A: The connector is designed for secure engagement, but excessive cycling should be minimized to preserve mechanical integrity.

Field Installation Guidelines

• Maintain straight routing of the 3.3 m cable to preserve coaxial impedance.

• Avoid tight bends near the ClickLoc connector to prevent distortion of the sensing path.

• Ground shielding at the Proximitor end only to avoid ground‑loop interference.

• Separate cable runs from high‑current conductors to reduce electromagnetic coupling.

• Verify system gap voltage after installation to confirm correct transducer chain behavior.
