Product Introduction (Rotation Engine)
Turbomachinery protection depends on clean, repeatable shaft-position measurement. The EMERSON PR6423/002-041 is an EPRO non-contact eddy current probe designed for critical rotating equipment such as steam turbines, gas turbines, compressors, fans, and pumps. It measures the gap between the probe tip and the conductive shaft surface, producing a signal proportional to static position and dynamic vibration.
The PR6423/002-041 is intended to be used as part of a calibrated measurement chain together with an EPRO converter such as CON041 and the correct extension cable. The probe is factory-calibrated with its matched converter, so field installation focuses on setting the correct air gap and verifying output signal quality. For plants running EPRO-based vibration monitoring systems, this probe is a practical replacement for maintenance turnarounds, probe damage, or legacy system upgrades.

Key Selling Points & Differentiators
- Factory-calibrated probe/converter pair for stable, repeatable measurements.
- Non-contact design avoids mechanical wear and suits high-speed rotating shafts.
- Compatible with EPRO CON041-based vibration monitoring systems.
- Suitable for steam turbines, gas turbines, compressors, fans, and pumps.
- Factory-sealed surplus reduces DOA risk compared with pulled used probes.
- 1-year functional warranty covers manufacturing defects and DOA failures.
- Not recommended as a velocity sensor, accelerometer, PLC module, DCS I/O card, or standalone transmitter.
Quality Transparency SOP (DYNAMIC GENERATION)
- Visual inspection: Check probe tip, sleeve, thread, cable jacket, connector, and labeling for damage.
- Part verification: Confirm PR6423/002-041, cable length, and connector type against the packing list.
- Resistance/insulation check: Verify cable continuity and insulation integrity before shipment.
- Converter pairing check: Confirm compatibility with CON041 or specified EPRO converter.
- Gap verification: Validate nominal gap behavior on a calibrated test setup when possible.
- Final packing: Anti-static bag, moisture barrier, shock-safe boxing, and photo-documented QA.
Technical Risk Avoidance (DYNAMIC GENERATION)
❗ Do not mix PR6423/002-041 with a different PR6423 sub-model or converter family. EPRO probes are calibrated as a matched measurement chain.
❗ Verify the correct air gap before commissioning. PR6423 probes typically use a nominal gap around 1.5 mm, but the final setpoint must follow the installed converter and system manual.
❗ Confirm cable length and connector type. The “-041” suffix relates to converter compatibility; cable and mechanical options are defined by the full part number.
❗ Do not use this probe as a casing vibration sensor. It measures shaft-relative displacement, not bearing housing velocity.
Buyer’s FAQ
Is this a genuine OEM part?
Yes. This is an OEM Emerson/EPRO PR6423 component supplied as new surplus / factory sealed. We do not rebrand or relabel third-party equivalents.
Is it new or refurbished?
Listed as New Original (New Surplus) / Factory Sealed unless otherwise stated. Any deviation in condition will be disclosed before shipment.
Can I use it as a direct replacement?
Yes, for EPRO PR6423 applications paired with a CON041-type converter. Confirm the full sub-model, cable length, and converter compatibility first.
What does the “-041” suffix mean?
It indicates compatibility with the CON041 converter family. Always verify the complete part number against your installed system.
What warranty is included?
A 1-year functional warranty covers manufacturing defects and DOA failures. Damage from incorrect gap setting, wrong converter pairing, or improper installation is not covered.
