PR9350/02 EPRO Precision Shaft Vibration Probe

Product Overview

The PR9350/02 is a premier eddy current sensor designed for non-contact measurement of shaft vibration and axial displacement. Specifically developed for high-speed rotating machinery, it offers exceptional signal stability and accuracy within 1.5% of the full scale. Whether deployed in gas turbines or centrifugal compressors, this probe delivers the high-fidelity data necessary for sophisticated Condition Monitoring Systems (CMS), ensuring long-term reliability in demanding environments.

Technical Configuration

Engineered for high-frequency applications, the hardware supports a frequency response up to 5000 Hz, capturing both slow-roll eccentricity and high-speed rotor dynamics. This unit features a robust sensing tip paired with a 5-meter extension cable for low-noise signal transmission. Its wide operating temperature range (-35 to 125 °C) and compatibility with API 670 standards make it a versatile choice for global power generation and petrochemical facilities.

Technical Specifications

Installation & Maintenance Guide

Proper mechanical mounting of the PR9350/02 requires adjusting the mechanical gap while monitoring the DC voltage to ensure the sensor operates within its linear range. Connect the shielded extension cable securely to the monitor to prevent signal drift. Regular inspection of the mounting point is recommended to ensure the sensor remains perpendicular to the shaft surface, preventing measurement errors caused by misalignment.

Engineering Advantages

The PR9350/02 excels in extreme industrial conditions, providing precise measurements despite thermal expansion. Its high frequency response allows maintenance teams to detect early-stage bearing wear and gear mesh issues. The seamless integration with standard PLC systems and Epro monitors offers a cost-effective path for upgrading aging vibration protection systems with modern, reliable hardware.

Technical FAQs

Q1: How do I verify the signal output?
A1: Measure the voltage between the output and common leads; it should read between -4 and -20 VDC depending on shaft proximity.

Q2: Is it compatible with non-Epro monitors?
A2: Yes, it is compatible with most PLC and API 670 compliant systems that accept a -4 to -20 VDC signal input.

Q3: Does it include a calibration certificate?
A3: This standard package does not include a certificate, but the sensor is factory-calibrated for high-precision industrial use.
