Bently Nevada 330103-00-04-05-02-CN 3300 XL 8 mm Proximity Probe

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Monitoring

The 3300 XL 8 mm proximity probe uses eddy-current measurement technology to convert shaft displacement into electrical signals for machinery condition monitoring. Therefore, the probe provides a proportional output based on the distance between the probe tip and the observed rotating surface.

The probe operates as part of a calibrated proximity measurement chain, which includes the probe, extension cable, and proximity transducer. Moreover, correct eddy-current probe scaling depends on the complete system configuration and target material characteristics.

Bently Nevada vibration monitoring systems apply gap voltage validation methods during installation. The standard measurement process uses gap voltage targets near -10 VDC to confirm correct probe positioning and signal range. Additionally, the system configuration supports rotor dynamics analysis by providing displacement information required for shaft position, vibration, and mechanical behavior evaluation.

Field Installation Guidelines

Install the probe with the specified M10 x 1 thread connection and maintain correct mechanical alignment with the monitored shaft surface. Ensure the probe tip maintains the required installation gap according to the connected Bently Nevada proximity transducer configuration.

Route the miniature coaxial cable away from high-current power conductors and strong electromagnetic interference sources. Furthermore, maintain proper cable shielding and grounding practices to reduce electrical noise during signal transmission.

Verify the probe gap voltage after mechanical installation. The measured value should match the configured monitoring system requirements, with typical Bently Nevada installations using approximately -10 VDC as a reference target for correct operating position.

Avoid excessive bending or mechanical stress on the ClickLoc connector and cable assembly. Confirm connector engagement before commissioning the vibration or position monitoring channel.
