EPRO PR6426/010-140 Eddy Current Sensor & CON021/912-160 Transmitter – Precision Shaft Vibration Monitoring System
When an eddy current sensor fails mid-operation on a high-speed turbine or centrifugal compressor, the consequences are immediate and severe: blind spots in vibration data, undetected shaft displacement, and the very real risk of catastrophic bearing failure or unplanned shutdown. In critical rotating machinery, there is no acceptable substitute for a calibrated, OEM-matched sensor-transmitter pair — and that is precisely what the EPRO PR6426/010-140 + CON021/912-160 delivers.
The PR6426/010-140 belongs to EPRO’s industry-standard PR6426 eddy current sensor series, engineered for non-contact, continuous measurement of shaft radial vibration and axial displacement in accordance with API 670 machinery protection standards. Paired with the CON021/912-160 signal conditioning transmitter, this kit forms a complete, calibrated measurement chain trusted by OEMs and plant engineers across power generation, oil & gas, and petrochemical industries worldwide.

Frequently Asked Questions
Q: Is the PR6426/010-140 interchangeable with the PR6426/010-100?
A: The suffix “140” denotes the integral cable length (140 mm). The -100 variant has a 100 mm cable. Electrically and mechanically compatible within the same mounting bracket, but verify cable routing clearance before substitution.
Q: Can the CON021/912-160 transmitter be used with other PR6426 variants?
A: Yes — the CON021 series transmitters are designed to work across the PR6426 sensor family. Always confirm the full part number pairing to ensure factory calibration is maintained.
Q: Do you provide calibration certificates?
A: We can provide available OEM documentation. For recalibration services, we recommend engaging an accredited metrology lab or the OEM service center.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units; 2–4 weeks for sourced/allocated stock. Contact us for real-time availability.
Q: Is this product suitable for use in hazardous (ATEX/IECEx) areas?
A: Please confirm the specific variant’s ATEX certification with our team before installation in Zone 1/2 classified areas. Not all PR6426 sub-variants carry Ex certification.
