RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Solving the Discontinued Hardware Crisis

The Bently Nevada 3300 Series was the industry standard for rotating machinery protection across petrochemical, power generation, and heavy manufacturing for over two decades. Thousands of turbines, compressors, and pumps worldwide still run on 3300 Series monitors — not because operators are unaware of the 3500 Series, but because the cost and risk of migration during active production cycles is prohibitive.

The 330101-00-77-15-02-CN probe is the primary sensing element in these systems. It measures shaft displacement and vibration via eddy current technology, feeding real-time data to the monitor rack. There is no software patch, no firmware update, and no workaround that substitutes for a functioning probe. When this component fails, the protection loop is broken.

The risk is not the probe itself. The risk is not having one when it is needed.

Condition & Reliability Assurance

DriveKNMS applies a 5-step inspection protocol to all 3300 Series proximity probes before dispatch review:

• Step 1 – Visual and mechanical inspection: Probe tip, cable jacket, and connector body examined for physical damage, corrosion, and deformation.
• Step 2 – Pin and connector integrity check: Coaxial connector pins inspected for oxidation, bending, and contact resistance. Corroded contacts are disqualified.
• Step 3 – Coil continuity and impedance verification: Eddy current coil continuity confirmed. Open or shorted coils are rejected without exception.
• Step 4 – Cable insulation resistance test: Cable insulation tested for breakdown, particularly at the probe-to-cable junction — the most common failure point in aged assemblies.
• Step 5 – Firmware and labeling verification: Part number, date code, and revision markings cross-referenced against Bently Nevada documentation to confirm authenticity and specification compliance.

Key Features for System Maintenance

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Can this probe be used with the Bently Nevada 3500 Series?
The 3300 XL 8mm probe system is not directly interchangeable with 3500 Series transducer systems due to differences in proximitor design and system calibration. This probe is intended for 3300 Series applications only.
