Solving the Discontinued Hardware Crisis

The Bently Nevada 3300 Series was the industry standard for turbomachinery protection across petrochemical, power generation, and heavy industrial facilities for decades. Many of these installations remain in active service — not because operators are unaware of the discontinuation, but because the cost and risk of migrating to a current-generation system (such as the 3500 Series) during live production is prohibitive.

The 330103-00-05-90-02-05 probe interfaces directly with 3300 Series monitors without signal chain reconfiguration. A failed probe replaced with this unit restores the protection loop to its original validated state. There is no firmware update, no recalibration of the monitor card, and no requalification of trip setpoints. For a facility operating under API 670 compliance requirements, this matters: substituting a non-OEM-equivalent sensor can trigger a full protection system review. A like-for-like replacement does not.

Condition & Reliability Assurance

• Step 1 – Visual & Mechanical Inspection: Probe tip, cable jacket, and connector body examined for physical damage, corrosion, and deformation. Units with compromised cable integrity are rejected.
• Step 2 – Connector Pin Inspection: All connector pins checked for oxidation, bending, and contact resistance. Corroded pins are a primary failure mode in stored proximity probes and are not acceptable.
• Step 3 – Electrolytic Component Assessment: Where applicable, internal components are assessed for signs of electrolytic degradation consistent with long-term storage.
• Step 4 – Firmware / Configuration Verification: For probes with embedded identification or configuration data, version integrity is confirmed against known-good references.
• Step 5 – Functional Verification: Output characteristics are verified against specification prior to packaging. Units that do not meet specification are not shipped.

Units are shipped in anti-static packaging with individual inspection records. Condition grade (New / Refurbished-to-Spec) is declared on the shipping documentation.

Key Features for System Maintenance

• Drop-in replacement: Direct mechanical and electrical compatibility with 3300 Series monitor inputs. No signal conditioning changes required.
• No reprogramming required: The monitor card does not require reconfiguration when replacing a like-for-like probe. Trip setpoints, gap voltage references, and alarm thresholds remain valid.
• Avoids engineering rework costs: A validated replacement eliminates the need for protection system re-engineering, third-party review, or API 670 requalification triggered by non-equivalent substitution.
• Supports long-term asset strategy: Securing spare inventory now removes single-point-of-failure risk from your maintenance plan for the remaining service life of the system.
• Documented provenance: Each unit ships with condition documentation, supporting your maintenance records and audit trail.

How do I confirm the unit is new or refurbished-to-spec?
Condition grade is declared on the shipping documentation and confirmed in writing prior to order confirmation. We do not ship units without a declared condition grade.

Should I purchase more than one unit?
For any obsolete component in a critical protection loop, holding a minimum of two spare units is standard practice. If one probe fails during a planned outage, a second spare ensures you are not exposed during the subsequent run period. Given the scarcity of 3300 Series inventory on the open market, procurement delay risk is real.
