Bently Nevada 330104-00-09-10-02-00 3300 XL 8 mm Proximity Probe

The Bently Nevada 330104-00-09-10-02-00, also cataloged as the 3300 XL 8 mm Proximity Probe, operates as a dedicated hardware component for non-contact shaft vibration and position measurement within machinery protection systems. The integrated eddy-current sensor coil generates a high-frequency electromagnetic field at the probe tip to observe real-time static and dynamic distance variations relative to a conductive target surface.

Hardware Specifications

Mechanical Monitoring & Eddy-Current Probe Scaling

The 3300 XL 8 mm proximity probe system delivers a calibrated incremental scale factor of 7.87 V/mm (200 mV/mil) when properly paired with a 3300 XL Proximitor Sensor and matched extension cable assembly. Field setup requires gap voltage validation to establish the baseline physical offset, targeting a nominal output of -10 VDC during static shaft positioning (representing the midpoint of the linear operating range). Proper orthogonal mounting mitigates cross-talk suppression issues when multiple probes are installed in close proximity, preserving signal accuracy across complex rotor dynamics applications.

Frequently Asked Questions

Q: How is the physical gap voltage set during field installation?

A: Thread the probe into its M10 x 1 mounting tap while monitoring the DC voltage output of the connected Proximitor Sensor. Rotate the probe until the measured signal reaches -10 VDC, confirming the probe tip is positioned at the center of its calibrated linear range.

Q: What precautions should be taken with the ClickLoc coaxial connector?

A: Ensure the miniature coaxial connector is securely engaged to prevent signal attenuation or intermittent connection. When installed in harsh or damp locations, insulate the connector junction with protective boot assemblies or self-fusing silicone tape to prevent moisture ingress.

Field Installation Guidelines

• Maintain recommended physical spacing between adjacent probe tips to eliminate mutual inductive coupling and cross-talk interference.

• Verify target material properties; factory calibration standard assumes 4140 AISI steel unless customized signal conditioning is configured.

• Observe minimum bend radius limits for the 1.0 m armored coaxial cable to prevent internal conductor crimping or dielectric breakdown.

• Ensure the probe housing is grounded mechanically through the mounting fixture while keeping the coaxial cable shield isolated from intermediate conduit grounds.
