EPRO PR9268/205-000 Eddy Current Probe

Product Overview

The PR9268/205-000 is a rugged, non-contact eddy current sensor designed for critical displacement and vibration monitoring. Optimized for turbines and compressors, its reverse-mount design allows for effortless installation from the exterior of the machine housing. By delivering high-fidelity signal stability without mechanical wear, it serves as a primary defense for large-scale rotating assets in extreme industrial environments.

Technical Configuration

This unit features a specialized reverse-mount body and an integrated 5-meter low-noise cable. The hardware is calibrated for seamless integration with EPRO MMS monitoring systems, ensuring a linear sensitivity of 8 V/mm. Its robust construction eliminates the need for complex field adjustments, providing a reliable plug-and-play solution for high-temperature shaft monitoring.

Technical Specifications

Installation & Maintenance Guide

To install the PR9268/205-000, secure the probe into the reverse-mount port and adjust the gap until the output voltage reaches approximately -10 VDC. This ensures the sensor operates at the center of its linear range. Always verify that the target shaft surface is clean and free of magnetic interference. Keep the 5-meter cable away from high-voltage lines to prevent EMI signal noise.

Engineering Advantages

The PR9268/205-000 excels in durability, maintaining precision across a wide temperature spectrum. The reverse-mount architecture is a significant time-saver, allowing maintenance teams to service the probe without opening bearing pedestals. Its high frequency response makes it equally effective for detecting both slow-roll eccentricity and high-speed blade passing frequencies.

Technical FAQs

Q1: What does a -24V output indicate?
A1: A constant -24V signal usually indicates an "open circuit" or that the probe tip is too far from the target surface to detect a signal.

Q2: Is the cable length customizable?
A2: No. The electronics are factory-tuned to the specific 5-meter cable impedance. Shortening the cable will compromise the measurement accuracy.

Q3: Does it support third-party PLCs?
A3: Yes, as long as the PLC analog input can process a -2 to -18 VDC signal, this sensor can integrate with most standard industrial controllers.
