Product Introduction (Rotation Engine)
Speed reference signals are critical for overspeed protection, phase measurement, and vibration analysis on rotating equipment. The EMERSON PR9376/010-011 is an EPRO Hall Effect speed probe designed for steam turbines, gas turbines, compressors, fans, pumps, and hydroturbines. It detects gear teeth, slots, or keyway marks on a rotating shaft and outputs a clean rectangular pulse signal, even at very low speeds.
This probe is part of the EPRO MMS 3000 / MMS 6000 machinery monitoring ecosystem and is commonly used together with speed monitoring modules such as the A6370 and compatible signal conditioners. The PR9376/010-011 includes a 5 m armored cable and an M18×1.5 mounting kit, making it suitable for retrofitting legacy installations or replacing damaged probes during maintenance turnarounds.

Key Selling Points & Differentiators
- Hall Effect design delivers stable rectangular pulses down to near-zero speed.
- 0–20 kHz range supports both low-speed and high-speed turbomachinery.
- 5 m armored cable improves mechanical protection and EMI resistance.
- Compatible with EPRO MMS 3000 / MMS 6000 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 PR6423/PR6424 eddy-current displacement probe, velocity sensor, accelerometer, PLC input, or DCS I/O card.
Quality Transparency SOP (DYNAMIC GENERATION)
- Visual inspection: Check probe body, M18 mounting kit, cable jacket, armor, connector, and labeling.
- Part verification: Confirm PR9376/010-011, 5 m armored cable, and mounting accessories against the packing list.
- Cable integrity check: Verify continuity, insulation, and armor condition before shipment.
- Output verification: Confirm pulse output behavior on a compatible test setup when possible.
- Mounting compatibility check: Validate M18×1.5 fitment against the installed bracket or gear housing.
- Final packing: Anti-static bag, moisture barrier, shock-safe boxing, and photo-documented QA.
Technical Risk Avoidance (DYNAMIC GENERATION)
❗ Do not substitute PR9376/010-011 with PR6423 or PR6424 eddy-current probes. PR9376 is a Hall Effect speed/keyphasor probe, not a displacement sensor.
❗ Verify the gear tooth profile, module, and air gap before commissioning. The recommended measuring gap is typically ≤1.5 mm, but the final setpoint must follow the installed monitoring module manual.
❗ Confirm cable length and mounting configuration. PR9376/010-001, PR9376/010-011, and PR9376/010-021 differ mainly in cable length.
❗ Do not use this probe as a casing vibration sensor or axial displacement probe. It is intended for speed and keyphasor reference only.
Buyer’s FAQ
Is this a genuine OEM part?
Yes. This is an OEM Emerson/EPRO PR9376 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 PR9376 speed/keyphasor applications. Confirm the cable length, mounting kit, and compatible monitoring module first.
What does “PR9376/010-011” mean?
It identifies the Hall Effect speed probe with a 5 m armored cable and M18×1.5 mounting kit. Other suffixes indicate different cable lengths.
What monitoring modules is it compatible with?
It is commonly used with EPRO MMS 3000 / MMS 6000 systems and speed monitoring modules such as the A6370. Always verify module compatibility with your system documentation.
What warranty is included?
A 1-year functional warranty covers manufacturing defects and DOA failures. Damage from incorrect air gap, wrong module pairing, or improper installation is not covered.
