Product Overview

The Emerson EPRO PR9376/20 serves as a high-precision, non-contact sensing element for advanced machinery protection. This 8mm eddy current probe measures shaft vibration, radial displacement, and eccentricity in critical rotating assets. Designed for seamless integration with EPRO CON signal converters (such as CON021) and MMS/AMS monitoring systems, it provides the primary data required for predictive maintenance. We supply this unit as 100% Brand New and Factory Sealed, ensuring laboratory-grade accuracy for your turbines, compressors, and pumps.

Engineering Advantages

Non-Contact Precision: The probe utilizes electromagnetic induction to measure the distance to the target shaft. This eliminates mechanical friction and wear, allowing for continuous monitoring at rotational speeds that would destroy contact-based sensors.
Compact 2-Meter Integration: The 2.0-meter fixed cable suits installations with tight space constraints or nearby junction boxes. This shorter length minimizes cable management issues and reduces potential signal attenuation before the signal reaches the driver/converter.
Extreme Thermal Resilience: The PR9376/20 withstands temperatures up to 180 °C. This allows for direct mounting inside turbine housings and near hot bearings where standard electronics fail.
EMI/RFI Immunity: High-quality shielding within the integrated cable rejects electromagnetic interference from surrounding high-voltage equipment, ensuring that your vibration data remains untainted by electrical noise.

FAQs

Can I extend the 2-meter cable of the PR9376/20?

The 2.0-meter cable length is fixed and factored into the sensor's calibration. If your installation requires a longer reach, you must use a specific EPRO extension cable that matches the system's total required electrical length (typically 5m or 10m total). Never cut or splice the cable manually.
Does the PR9376/20 require an external driver?

Yes. Like all passive eddy current probes, the PR9376/20 requires a signal converter (driver) such as the EPRO CON021. The converter provides the excitation voltage and translates the probe's return signal into a 0-10V or 4-20mA industrial signal.
How do I ensure the probe is correctly gapped during installation?

You must monitor the DC "Gap Voltage" at the signal converter while threading the probe into its mount. For most EPRO systems, adjust the probe until you achieve a stable -10V DC reading, which indicates the probe sits exactly in the center of its linear measurement range.
Is this probe resistant to aggressive turbine oils?

The PR9376/20 features a stainless steel body and a chemically resistant tip. It operates reliably while fully submerged in mineral or synthetic turbine oils and remains sealed against high-pressure environments common in oil-flooded bearings.
