Bently Nevada 330901-00-16-05-02-CN 3300 XL 8mm Proximity Probe

Configured for high-frequency radial vibration and axial position sensing, the Bently Nevada 330901-00-16-05-02-CN (3300 XL 8mm Proximity Probe) provides direct physical signal acquisition for fluid-film bearing machinery.

Suffix Breakdown & Model Matrix

Hardware Specifications

Mechanical Monitoring and TSI Integration

The 3300 XL 8 mm system operates on the eddy-current principle to measure the distance between the probe tip and the observed conductive surface. Precise probe scaling is required to maintain linear voltage output; deviations from standard eddy-current probe scaling can introduce measurement errors in rotor dynamic analysis. During field commissioning, verify that gap voltage validation targets reach -10 VDC at mid-range to ensure the sensor operates within its linear range. Maintaining signal integrity is achieved through proper shielding and cross-talk suppression techniques, which are required to isolate dynamic vibration signals from ambient electrical noise in harsh industrial environments.

Frequently Asked Questions

Q: Can this 8 mm probe be used with the 3300 NSv (Narrow Side View) Proximitor sensor?

A: No. The 330901 8 mm probe and the 3300 NSv probe have different coil inductances and electrical characteristics; they are not interchangeable and require their respective, matched Proximitor sensors.

Q: Is the ClickLoc connector compatible with legacy 3300 series transducer cables?

A: Yes. The ClickLoc connector is designed to be backwards compatible with earlier 3300 series transducer systems, allowing for seamless integration into legacy installations without replacing the entire signal path.

Field Installation Guidelines

1. Probe Mounting: Use the provided jam nuts to secure the probe in the mounting bracket. Ensure the probe tip is perpendicular to the shaft surface to prevent measurement distortion.
2. Torque Specifications: Apply the recommended installation torque (typically 5.1 N m for 3/8-24 threads) to prevent deformation of the probe casing, which could impact sensitivity.
3. Shielding: Ensure the coaxial cable shield is grounded at the Proximitor end only, unless specific machine train grounding requirements dictate otherwise, to prevent ground loop currents.
4. Connector Inspection: Prior to mating the ClickLoc connector, inspect the interior for moisture or debris. Ensure the locking collar clicks into place to maintain an IP67-rated seal against process fluids.
