3. Product Introduction
The EPRO PR6424/010-040 + CON021 system is installed where large rotating shafts require accurate non-contact displacement measurement. The stainless-steel probe head mounts close to the shaft target, while the CON021 converter transforms the eddy current signal into a monitoring output for machinery protection systems (which is essential for turbine and compressor protection loops).
Built for critical turbomachinery applications, the PR6424 series is commonly used on steam turbines, gas turbines, hydro turbines, compressors, pumps, and fans. The 16 mm probe design provides a larger measurement range than smaller PR6423 sensors, making it suitable for applications requiring extended shaft movement observation. Verify probe range, cable length, converter type, and existing protection system calibration before installation.

5. ? Global Compliance & Industry Certifications
Expected regulatory approvals and compliance considerations for the EPRO PR6424/010-040 + CON021 include:
- CE Mark: Applicable for supported Emerson EPRO machinery monitoring configurations.
- ATEX / IECEx: Available for selected PR6424 and converter combinations when the correct hazardous-area version and installation accessories are used.
- UL/cUL Recognition: May apply depending on regional configuration and complete monitoring system approval.
- Marine Approvals (DNV GL): Applicable only when included within a certified marine machinery monitoring package.
- API 670 Compatibility: The PR6424 family is designed for machinery protection applications aligned with common turbomachinery monitoring practices.
For hazardous-area service, certification applies to the complete measurement chain. The probe, converter, cable, barriers, and monitoring equipment must all remain within the approved design boundary.
Verify specific lot certifications with OEM.
6. ? Long-Term Storage & Asset Preservation Guide
Keep the PR6424 probe and CON021 converter sealed in their original anti-static packaging. The LEMO connector, converter terminals, and precision sensing surfaces should remain protected from dust and moisture.
Maintain warehouse humidity below 60% RH. Avoid chemical storage areas, salt-air environments, and locations with corrosive vapors because connector plating and metallic surfaces can deteriorate over time.
Inspect stored units every 12-24 months. Check the probe tip, stainless-steel housing, PTFE cable jacket, converter enclosure, and identification labels. Before commissioning, verify calibration records and confirm the converter matches the installed machinery protection channel.
7. Physical Installation Prerequisites
- Install the PR6424 probe with the correct mechanical gap from the shaft target.
- Confirm the shaft material meets the required ferromagnetic target specification.
- Secure the M18 × 1.5 threaded housing using approved mounting practices.
- Install the CON021 converter inside a protected instrumentation cabinet.
- Maintain at least 50 mm clearance around cabinet ventilation paths where enclosure design permits.
- Verify cabinet grounding and shield termination.
- Separate sensor wiring from high-current motor and VFD cables.
- Protect the probe cable from abrasion, sharp bending, and excessive mechanical stress.
- Confirm output scaling before connecting to the vibration monitoring system.
8. Buyer’s FAQ (Logistics & Compliance Focus)
Q: What HS Tariff Code is commonly used for an EPRO PR6424/010-040 + CON021 shipment?
A: Eddy current displacement measurement systems are commonly reviewed under HS classifications associated with measuring and testing instruments, often within heading 9031. Final classification depends on customs interpretation and declared product function.
Q: Why should Country of Origin documentation be verified?
A: COO records support customs clearance, warranty traceability, and machinery protection audit documentation. Verify the country marking on both the probe and converter packaging before warehouse acceptance.
Q: Is shipping insurance recommended for this sensor assembly?
A: Yes. The probe contains precision electromagnetic sensing components, and the converter contains calibrated electronic circuitry. Transportation impact or moisture exposure may create failures that only appear during commissioning.
Q: Does the PR6424/010-040 + CON021 include the latest firmware pre-loaded?
A: No. The PR6424 probe and CON021 converter are hardware measurement components and do not contain user-loaded firmware. Confirm calibration data, sensor range, converter compatibility, and machinery protection settings before installation.
