Product Overview

The Emerson EPRO PR9376/010-011 serves as a high-precision, non-contact sensing element for advanced machinery protection systems. This 8mm eddy current probe measures relative shaft vibration, radial displacement, and eccentricity in critical rotating assets like turbines and high-speed compressors. Designed for seamless integration with EPRO CON signal converters (such as the CON021) and MMS/AMS monitoring racks, it provides the primary data required for predictive maintenance. We supply this unit as 100% Brand New and Factory Sealed, ensuring original manufacturer accuracy for your industrial infrastructure.

Technical Specifications

The PR9376/010-011 delivers consistent measurement performance under extreme thermal and mechanical stress.

Engineering Advantages

• Non-Contact Precision: The probe utilizes electromagnetic induction to monitor the distance to the target shaft. This eliminates mechanical friction and wear, allowing for continuous monitoring at surface speeds that would destroy contact-based sensors.

• Optimized for Tight Spaces: The 1.0-meter fixed cable suits installations with limited mounting clearance or nearby junction boxes. This shorter length minimizes cable management complexity and reduces the risk of snagging during routine maintenance.

• High Thermal Resilience: The PR9376/010-011 withstands temperatures up to 180 °C. This rating permits direct mounting inside turbine housings and near hot bearings where standard electronics typically fail.

• EMI/RFI Immunity: High-quality shielding within the integrated cable rejects electromagnetic interference from surrounding high-voltage equipment, ensuring your vibration data remains accurate and free from electrical noise.

FAQs

• Does the PR9376/010-011 require an external driver?Yes. Like all passive eddy current probes, the PR9376/010-011 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.

• Can I extend the 1-meter cable?The 1.0-meter cable length is factory-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 splice the cable manually.

• How do I ensure the probe is correctly gapped during installation?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. This indicates the probe sits exactly in the center of its linear measurement range.

• Is this probe resistant to turbine lubricating oils?The PR9376/010-011 features a stainless steel body and a chemically resistant tip. It operates reliably while submerged in mineral or synthetic turbine oils and remains sealed against high-pressure environments common in oil-flooded bearings.
