330905-00-25-05-12-CN Bently Nevada 3300 NSv Proximity Probe

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Monitoring

The Bently Nevada 330905-00-25-05-12-CN uses eddy-current probe scaling to convert shaft displacement into proportional electrical output signals. The probe provides an average scale factor of 7.87 V/mm (200 mV/mil), allowing the connected Proximitor Sensor and monitoring system to process radial and axial position changes.

Additionally, the 3300 XL NSv design supports rotor dynamics monitoring by providing displacement feedback from rotating machinery shafts. The compact M10 x 1 threaded structure allows installation in locations where standard 3300 and 3300 XL 5 mm or 8 mm transducer systems cannot fit.

The probe configuration maintains signal characteristics required for gap voltage validation and mechanical position measurement. Bently Nevada monitoring systems typically use -10 VDC target gap voltage validation to confirm correct probe operating position.

Frequently Asked Questions

Q: What transducer systems can use the 330905-00-25-05-12-CN probe?
A: The probe operates as part of the 3300 XL NSv Transducer System and can replace 3300 RAM Transducer Systems and 3000-series or 7000-series 190 Transducer Systems when the complete NSv components are applied.

Q: Does this probe include an armored construction design?
A: No. The 330905-00-25-05-12-CN uses a non-armored configuration with a FluidLoc cable and miniature coaxial ClickLoc connector.

Q: What mechanical installation limitation does this probe address?
A: The M10 x 1 thread, 0 mm unthreaded length, and compact case design support installations with restricted clearance, including sideview, rearview, and counter bore mounting conditions.

Field Installation Guidelines

Install the 330905-00-25-05-12-CN probe according to the specified M10 x 1 mounting requirements. Verify the mechanical clearance before installation because the 250 mm overall case length and compact body design are intended for restricted mounting locations.

Route the FluidLoc cable away from high-current conductors, ignition sources, and strong electromagnetic interference areas. Maintain proper cable routing practices to reduce unwanted signal noise.

Connect the miniature coaxial ClickLoc connector securely to the compatible extension cable and Proximitor Sensor. Verify probe gap voltage during commissioning to confirm correct shaft target positioning before placing the machinery protection channel into service.
