The Bently Nevada 330701-00-30-10-01-00, also cataloged as the 330701 3300 XL 11 mm Proximity Probe, operates as a dedicated hardware component for non-contact shaft displacement measurement within the Bently Nevada 3300 XL Proximity Transducer System.

Model Configuration Overview

The 330701-00-30-10-01-00 configuration defines a 3300 XL 11 mm proximity probe assembly with a 1/2-20 UNF thread design, 0.0 in minimum unthreaded length, 3.0 in case length, 1.0 meter standard cable, and miniature coaxial ClickLoc connector with connector protector.

The probe is designed for connection with a compatible 3300 XL Proximitor Sensor to provide eddy-current measurement signals for vibration, radial position, axial position, and mechanical displacement monitoring.

Hardware Specifications

Eddy-Current Measurement and Rotor Dynamics Characteristics

The 330701-00-30-10-01-00 uses eddy-current sensing technology to measure the distance between the probe tip and conductive rotating surfaces. The measurement output depends on the probe gap voltage established by the connected Proximitor Sensor.

The 3300 XL system supports gap voltage validation using standard -10 VDC target calibration conditions. Correct probe installation and gap adjustment are required to maintain accurate displacement measurements.

The probe assembly incorporates TipLoc and CableLoc construction methods to maintain mechanical attachment between the probe tip, body, and cable connection area. The ClickLoc connector uses gold-plated brass contact surfaces to maintain electrical continuity under vibration conditions.

The system design supports rotor dynamics monitoring by providing proportional shaft displacement signals for vibration analysis, thrust position measurement, and differential expansion monitoring applications.

Rotor Monitoring Technical Features

The 330701-00-30-10-01-00 belongs to the Bently Nevada 3300 XL 11 mm proximity measurement platform. The system uses calibrated eddy-current scaling to convert shaft displacement into electrical output signals.

The probe design provides long linear measurement range characteristics and supports applications requiring large shaft movement measurement, including axial thrust position, piston rod position, and turbine expansion monitoring.

The 3300 XL Proximitor Sensor interface provides improved RFI/EMI immunity, allowing operation in electrically noisy industrial environments without additional mounting requirements.
