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

Technical Specifications

Note: Electrical parameters such as gap range, sensitivity, and frequency response are system-dependent and verified during our QA process. We do not publish unverified specifications.

Solving the Discontinued Hardware Crisis

The PR6426 series was the backbone of shaft monitoring on gas turbines, steam turbines, compressors, and large pumps across petrochemical, power generation, and heavy manufacturing facilities throughout the 1990s and 2000s. The sensor and its matched conditioner operate as a calibrated pair — substituting either component with an unmatched replacement invalidates the measurement chain and can trigger false trips or, more dangerously, mask real faults.

For plant managers under pressure to defer capital expenditure, sourcing a verified PR6426/010-000 + CON021/916-160 assembly is the lowest-risk, lowest-cost path to restoring full protection coverage. A single unplanned turbine trip caused by a monitoring gap can cost more in lost production than a decade of spare parts procurement.

How to extend your turbomachinery protection system life by 5–10 years using critical spare positioning:

These five steps, executed systematically, eliminate the primary failure modes that force premature system retirement. The capital cost is a fraction of a single unplanned outage.

Condition & Reliability Assurance

Sourcing obsolete industrial components from the spot market carries real risk. DriveKNMS applies a structured 5-step verification protocol to every PR6426/010-000 + CON021/916-160 unit before it leaves our facility:

1. Visual and mechanical inspection. Cable jacket integrity, connector pin condition, probe tip surface — any corrosion, mechanical damage, or evidence of prior field repair is documented and disclosed.
2. Electrolytic capacitor assessment. The CON021 conditioner contains electrolytic capacitors that degrade with age. Units showing capacitor bulge, leakage, or out-of-tolerance ESR are either recapped by our technicians or quarantined.
3. Firmware and hardware revision verification. Where revision markings are present, we confirm compatibility with the target MMS platform version. Mixed-revision assemblies are flagged.
4. Pin and connector corrosion check. All mating connectors are inspected under magnification. Oxidized contacts are treated; connectors with structural damage are replaced with OEM-equivalent parts.
5. Functional output verification. Each conditioner is bench-tested against a calibrated target to confirm output voltage linearity across the operating gap range. Results are recorded and available on request.

Key Features for System Maintenance

• Drop-in replacement. The PR6426/010-000 + CON021/916-160 is a direct substitute for the installed assembly. No wiring changes, no setpoint reconfiguration, no engineering intervention required.
• No reprogramming. The protection system sees an identical signal chain. Existing trip setpoints, alarm levels, and Bode plot baselines remain valid.
• Avoids engineering reconstruction costs. A modern sensor retrofit requires new conditioner cards, cable modifications, and full recalibration — typically 3–6 weeks of engineering time. A direct replacement eliminates this entirely.
• Preserves existing machinery baselines. Years of vibration trend data remain directly comparable. No baseline reset, no requalification period.

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

How do I know the unit is genuine and not a counterfeit?
Every unit we supply is physically inspected and functionally tested. We provide full traceability documentation including condition report and test results. We do not source from unverified secondary markets. If you require additional authentication steps, we will accommodate them.

Can you supply just the conditioner (CON021/916-160) separately?
Yes. Contact us with your specific requirement and we will confirm availability of individual components.
