Hardware Specifications

Eddy-Current Probe Scaling and Gap Voltage Validation

The 3300 XL 8 mm probe serves as the sensing element within a complete proximity transducer system consisting of a probe, extension cable, and Proximitor sensor. The probe measures dynamic shaft vibration and static shaft position through eddy-current interaction with a conductive target surface. During installation and commissioning, probe system scaling is verified through gap voltage measurements. For properly calibrated Bently Nevada proximity systems, nominal operating targets near -10 VDC are commonly used to verify that the probe is positioned within its linear measurement region. Maintaining proper gap voltage contributes to accurate rotor dynamic analysis and vibration monitoring performance.

Frequently Asked Questions

Q: Can the 330101-00-08-10-01-00 operate independently without a Proximitor sensor?
A: No. The probe is intended to operate as part of a complete Bently Nevada proximity transducer system that includes a compatible extension cable and Proximitor sensor.

Q: What machinery applications is the probe intended for?
A: The probe is designed for dynamic shaft vibration measurement and static shaft position monitoring on fluid-film bearing machinery.

Q: What connector configuration is provided?
A: The model includes a Miniature Coaxial ClickLoc connector with connector protector and standard cable assembly.

Field Installation Guidelines

• Verify compatibility between the probe, extension cable, and Proximitor sensor before installation.

• Ensure the target material and geometry conform to transducer system requirements.

• Route probe cables separately from motor feeders, switching circuits, and high-energy conductors.

• Avoid excessive cable bending, crushing, or tensile loading during installation.

• Secure the ClickLoc connector fully to maintain signal integrity.

• Confirm probe mounting rigidity to prevent structural vibration effects on measurements.

• Validate transducer gap voltage prior to placing the measurement channel into service.

• Inspect cable routing periodically for abrasion, contamination, or mechanical damage.
