Product Overview

The 330104-02-25-10-02-00 is a high-precision 8 mm eddy-current proximity sensor from the Bently Nevada 3300 XL series. This transducer is engineered to provide non-contacting measurements of vibration and shaft position in critical rotating machinery. Designed with a robust armored jacket, the probe is specifically intended for environments where the integral cable requires physical protection from abrasion or mechanical stress. It operates as a gap-to-voltage converter, translating the distance between the probe tip and a conductive metal target into a high-fidelity electrical signal for real-time diagnostic monitoring.

Industrial Deployment Context

The 330104-02-25-10-02-00 is a vital component in Turbine Supervisory Instrumentation (TSI) for large-scale rotating assets such as industrial compressors, steam turbines, and centrifugal pumps. Its armored construction makes it particularly effective in engine rooms and production floors where cables are exposed to heavy vibration, oil saturation, or accidental physical impact. Engineers utilize this probe to track radial vibration (imbalance/misalignment) and axial position (thrust bearing protection). By providing continuous data to 3500 series monitoring racks, it enables predictive maintenance strategies that reduce unplanned downtime and prevent catastrophic mechanical failure.

FAQ

Q: What is the primary advantage of the armored cable on this model?

A: The stainless steel armor provides a flexible yet rigid barrier that prevents the internal coaxial lead from being crushed, cut, or frayed. This is essential for installations where the cable must pass over sharp metal edges or is located in high-traffic maintenance areas.

Q: Is the 330104-02-25-10-02-00 compatible with standard 3300 XL extension cables?

A: Yes, this probe is part of the 3300 XL family and uses the standard gold-plated ClickLoc connector, making it fully compatible with all 3300 XL extension cables and Proximitor sensors.

Q: Can this probe be used for RPM or speed measurements?

A: Absolutely. It can be utilized as a Keyphasor sensor to detect a notch or projection on a shaft, providing a once-per-revolution pulse used for calculating rotational speed and vibration phase angles.

Q: What does the "00" agency approval option mean?

A: The "00" designation indicates that this probe does not carry specific hazardous area certifications (like ATEX or IECEx). It is intended for use in general industrial areas where explosive atmospheres are not a concern.

Q: How do I determine if the 25 mm case length is sufficient for my machine?

A: The 25 mm case length is a compact design for shallow mounting holes. You should measure the distance from your mounting bracket to the shaft surface to ensure the probe tip can reach within the 2.0 mm (80 mil) linear sensing range.
