Configured for shaft displacement measurement in the Bently Nevada 3300 XL Proximity Transducer System, the Bently Nevada 330703-000-150-10-11-05 (330703 3300 XL 11 mm Proximity Probe) provides direct physical signal detection through eddy-current sensing technology.

Configuration Identification

The 330703-000-150-10-11-05 is a 3300 XL 11 mm proximity probe configuration with an M14 x 1.5 mounting thread, unarmored construction, 150 mm case length, 1.0 meter cable length, miniature coaxial ClickLoc connector, FluidLoc cable design, and multiple agency approvals.

This probe is installed as part of a complete 3300 XL 11 mm Transducer System consisting of the probe, extension cable when required, Proximitor Sensor, and compatible monitoring hardware.

Hardware Data

Eddy-Current Scaling and Rotor Dynamics Monitoring

The 330703-000-150-10-11-05 operates through an eddy-current measurement circuit where probe gap distance is converted into an electrical displacement signal by the connected 3300 XL Proximitor Sensor.

The transducer system uses calibrated eddy-current probe scaling for shaft displacement measurement. Proper gap voltage validation, including standard -10 VDC target conditions, is required during installation and commissioning.

The probe output supports rotor dynamics analysis by providing displacement information for radial vibration, axial position, thrust movement, and differential expansion monitoring.

The FluidLoc cable construction prevents internal fluid migration through the cable structure, while the ClickLoc connector provides a vibration-resistant electrical interface between the probe, extension cable, and Proximitor Sensor.

Field Installation Guidelines

Mechanical Mounting

• Install the probe using the M14 x 1.5 mounting thread.
• Confirm mechanical clearance between the probe tip and rotating shaft surface before operation.
• Prevent impact loading or excessive mechanical force on the probe body.

Cable Installation

• Route the FluidLoc cable away from high-voltage and high-current wiring.
• Maintain the connector protector position to prevent contamination at the connection point.
• Avoid sharp bending near the probe body and ClickLoc connector.

Signal Verification

• Verify probe gap voltage after mechanical installation.
• Confirm correct connection between probe, cable, Proximitor Sensor, and monitoring input.
• Check signal stability before enabling machine protection functions.

Proximity Measurement System Characteristics

The Bently Nevada 3300 XL 11 mm system provides displacement measurement for machines requiring larger target-to-probe distances compared with smaller probe configurations.

The probe design maintains compatibility with 3300 XL monitoring architecture and supports replacement applications previously using 7200-series 11 mm and 14 mm transducer systems. System migration requires replacement of all related transducer components and compatible monitoring configuration updates.

The 3300 XL Proximitor Sensor interface provides RFI/EMI immunity characteristics for operation near high-frequency electrical sources and supports installation without additional shielding accessories when system requirements are met.
