Product Overview

The Emerson EPRO PR9350/04 operates as a high-performance, non-contact sensing solution for critical machinery diagnostics. This 5mm compact eddy current probe measures relative shaft vibration, radial displacement, and eccentricity in high-speed rotating equipment. Designed specifically for installations with severe space constraints, it integrates seamlessly with EPRO CON signal converters (such as the CON021) and MMS/AMS monitoring systems. We deliver this unit as 100% Brand New and Factory Sealed, ensuring laboratory-grade precision for turbines, compressors, and pumps in harsh industrial environments.

Engineering Advantages

Optimized for Restricted Access: The 5mm tip diameter allows for installation in narrow bearing housings where standard 8mm or 11mm probes cannot fit. This small form factor enables precise gap measurements without requiring significant mechanical modification to the machine casing.
Extended 4-Meter Integration: The fixed 4.0-meter cable provides sufficient length to reach local junction boxes while maintaining signal purity. This integrated design eliminates the need for intermediate connectors, reducing potential failure points in high-vibration zones.
Thermal Endurance: The sensor maintains linear accuracy at temperatures up to 180 °C. This resilience makes it suitable for monitoring hot-end bearings in steam turbines or high-pressure compressors where standard electronics fail.
Advanced Shielding: The rugged stainless steel housing and high-grade cable shielding reject electromagnetic interference (EMI). This ensures that your monitoring system receives pure vibration data, free from the "ghost" signals caused by nearby motors or high-voltage lines.
FAQs
Can the PR9350/04 replace a standard 8mm probe?Yes, provided you utilize the correct mounting adapter. While the 5mm tip is smaller, it offers similar accuracy; however, you must ensure the target area on the shaft satisfies the minimum diameter requirements for a 5mm probe to maintain signal linearity.
Does this probe require a signal converter?Yes. The PR9350/04 requires a converter such as the EPRO CON021 to generate the high-frequency excitation and translate the proximity change into a standardized 0-10V or 4-20mA signal for your PLC/DCS.
How do I calibrate the gap for a 5mm probe?Connect the probe to its converter and monitor the DC "Gap Voltage." Adjust the physical distance until the voltage matches the center of the linear range (typically -10V DC). Because of the 5mm tip's higher sensitivity to alignment, ensure the probe sits exactly perpendicular to the shaft surface.
Is the 4-meter cable length customizable?No. The 4.0-meter cable is factory-calibrated. Cutting or splicing this cable alters the electrical impedance and invalidates the factory calibration, leading to significant measurement errors.
