Product Overview

The Emerson EPRO PR9670/113-100 operates as a high-precision sensing element for non-contact machinery protection. This 8mm eddy current probe measures critical mechanical parameters, including shaft vibration, radial displacement, and eccentricity, without physical interaction. Designed for integration with EPRO CON signal converters (like the CON021) and MMS/AMS monitoring racks, it provides the primary data stream for turbomachinery safety. We deliver this unit as 100% Brand New and Factory Sealed, ensuring original manufacturer accuracy for your compressors, turbines, and gearboxes.

Technical Specifications

The PR9670/113-100 withstands extreme thermal and mechanical stress while maintaining signal linearity.

Engineering Advantages

• Extended 10-Meter Reach: The fixed 10-meter cable eliminates the need for intermediate connectors in many large-scale turbine installations. This direct connection reduces the number of potential failure points and signal attenuation issues commonly associated with extension cables.

• Non-Contact Reliability: By utilizing eddy current technology, the probe eliminates mechanical wear. This allows for continuous, high-speed monitoring of shaft dynamics that would cause traditional contact sensors to fail instantaneously.

• Thermal Resilience: The probe housing and tip assembly function reliably at temperatures up to 180°C. This high-temperature rating allows for installation deep within steam turbine housings or near hot bearing pedestals where standard sensors cannot survive.

• Advanced Signal Purity: High-quality shielding within the 10m cable rejects electromagnetic interference (EMI). This ensures that the vibration data remains accurate even when routed near high-voltage motor cables or power generators.

FAQs

• Can I cut the 10m cable to fit a shorter installation distance?

  No. You must never cut or modify the fixed cable length. The internal impedance and capacitance of exactly 10 meters of cable form a critical part of the sensor's calibration. Shortening the cable will shift the "Gap Voltage" and invalidate the measurement accuracy.

• Does the PR9670/113-100 require a specific driver?

  Yes. This probe requires an EPRO CON signal converter (such as the CON021). The converter provides the necessary high-frequency oscillation to the probe tip and translates the return signal into a 0-10V or 4-20mA signal usable by your PLC or DCS.

• What is the proper procedure for gapping this probe?

  During installation, monitor the DC "Gap Voltage" at the signal converter. Move the probe closer to or further from the shaft until the voltage reaches the center of the linear range (typically -10V DC for standard EPRO configurations). Tighten the locknuts only once you achieve this stable voltage.

• Is this probe resistant to turbine lubricating oils?

  Yes. The PR9670/113-100 features a fully sealed stainless steel body and a chemically resistant tip. It operates reliably while fully submerged in synthetic or mineral-based turbine oils and resists high-pressure environments.
