Product Introduction (Rotation Engine)
Large turbomachinery requires displacement probes with enough range and mechanical robustness to survive critical axial and radial measurements. The EMERSON PR6424/011-140 is an EPRO non-contact eddy current probe designed for steam turbines, gas turbines, compressors, fans, pumps, and hydroturbines. With a 16 mm probe head and approximately ±2.0 mm measuring range, it is better suited than smaller PR6423 probes for axial thrust position, large-displacement monitoring, and applications where a longer linear range is required.
The PR6424/011-140 must be used as part of a calibrated measurement chain together with an EPRO converter such as CON011, CON021, CON031, or CON041 and the correct extension cable. The probe and converter are factory-calibrated as a matched pair, so field work focuses on setting the correct air gap and verifying signal quality rather than bench recalibration. For plants maintaining EPRO-based TSI or MMS protection systems, this probe is a practical replacement for maintenance turnarounds, probe damage, or legacy system upgrades.

Key Selling Points & Differentiators
- 16 mm probe with ±2.0 mm range suits axial displacement and large-gap applications.
- Factory-calibrated probe/converter pair for stable, repeatable measurements.
- Compatible with EPRO CON0x1-based vibration and position 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, M18×1.5 thread, cable jacket, connector, and labeling for damage.
- Part verification: Confirm PR6424/011-140, 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 the installed CON0x1 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 substitute PR6424/011-140 with a PR6423 or PR6426 probe. PR6424 has a 16 mm head, ±2.0 mm range, and 4 V/mm sensitivity, which is not interchangeable with PR6423 (8 mm, ±1.0 mm, 8 V/mm) or PR6426 (larger range, lower sensitivity).
❗ Verify the correct air gap before commissioning. PR6424 probes typically use a nominal gap around 2.0 mm, but the final setpoint must follow the installed converter and system manual.
❗ Confirm cable length and connector type. The “-140” suffix relates to a specific cable/connector configuration; always verify the physical label before installation.
❗ 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 PR6424 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 PR6424 applications paired with a compatible CON0x1 converter. Confirm the full sub-model, cable length, and converter compatibility first.
What does the “-140” suffix mean?
It indicates a specific cable/connector configuration within the PR6424 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.
