Technical Specifications

Solving the Discontinued Hardware Crisis

The Bently Nevada 3300 XL platform was the industry standard for turbomachinery protection across oil & gas, power generation, and petrochemical sectors from the 1990s through the early 2010s. Thousands of installations worldwide remain in active service. The 330703 proximity probe is the primary sensing element in these systems — it converts shaft displacement into a voltage signal that the Proximitor and monitor interpret as vibration and position data.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

The 330703-000-150-10-11-05 is not interchangeable with 3500 series probes without recalibrating the entire measurement chain. Substituting an incompatible probe risks false readings, nuisance trips, or — more dangerously — missed alarm thresholds on a critical rotating asset. The only low-risk option for a plant committed to maintaining its existing 3300 XL architecture is a like-for-like replacement with the original part number.

How to extend your 3300 XL system life by 5 to 10 years at a fraction of migration cost:

The single most effective asset protection strategy for aging vibration monitoring infrastructure is pre-emptive spare parts procurement. A plant that holds two to four units of each critical probe model — purchased at current market prices — eliminates the emergency sourcing risk entirely. The cost of four 330703 probes is a rounding error against the cost of one unplanned outage. Pair this with a scheduled inspection cycle (every 18 to 24 months) covering probe tip condition, cable jacket integrity, and connector pin corrosion, and the 3300 XL system can remain in reliable service well beyond its nominal end-of-life date. This is not a workaround. It is standard practice in facilities where the cost of a protection system failure is measured in millions, not thousands.

Condition & Reliability Assurance

Every 330703 unit that leaves DriveKNMS has passed a structured 5-step inspection protocol developed specifically for legacy eddy-current transducers:

Step 1 – Electrolytic Capacitor Assessment: Internal passive components in aged probes are inspected for signs of electrolytic degradation. Units showing capacitance drift outside tolerance are rejected.

Step 2 – Output Sensitivity Verification: Each probe is bench-tested against a calibrated target to confirm the standard output sensitivity of -7.87 V/mm (−200 mV/mil), consistent with Bently Nevada factory specification.

Step 5 – Final Functional Test: The probe is tested in a complete measurement chain (probe + extension cable + Proximitor) to confirm end-to-end signal integrity before packaging.

Units that do not pass all five steps are not sold. There is no graded inventory. Every unit shipped is either new surplus or fully refurbished to functional equivalence.

Key Features for System Maintenance

The 330703-000-150-10-11-05 is a direct, drop-in replacement for any failed or degraded probe of the same part number within the 3300 XL measurement chain. No reconfiguration of the Proximitor sensor is required. No monitor recalibration is triggered. No engineering change order is needed for a like-for-like swap.

Q: How do I confirm the unit is new or properly refurbished — not a counterfeit?
A: We provide full inspection documentation with each shipment, including test records from our 5-step QA process. We do not source from unverified brokers. All units are physically inspected at our facility before dispatch. Customers requiring third-party verification can request independent testing prior to shipment.

Q: Can this probe be used with a 3500 series Proximitor?
A: No. The 3300 XL and 3500 series use different Proximitor electronics with different calibration curves. Mixing components from the two platforms will produce measurement errors and may compromise machinery protection integrity.
