Epro PR6423/004-000 8mm Eddy Current Sensor

Product Introduction

The Epro PR6423/004-000 is a high-performance non-contact eddy current displacement sensor, engineered specifically for critical machinery monitoring in industrial environments. Designed and manufactured by Epro (now under Emerson Process Management), this sensor forms part of a modular system intended for real-time monitoring of shaft displacement, vibration, and positioning of rotating equipment.

Featuring an 8mm probe diameter, the PR6423/004-000 offers excellent linearity, wide frequency response, and durability in harsh operating conditions. When used in conjunction with Epro’s CON0xx converters (such as CON021 or CON041), the sensor provides a complete measurement chain capable of withstanding high temperatures, contamination, and electromagnetic interference.

Technical Specifications

Product Applications

The PR6423/004-000 is built for demanding applications in critical rotating equipment. It is a preferred choice for:

• Steam and Gas Turbines – Shaft displacement, vibration, and thermal expansion monitoring.

• Centrifugal Compressors – Radial and axial position tracking for high-speed rotors.

• Pumps and Motors – Real-time diagnostics to detect imbalance, misalignment, and bearing wear.

• Gearboxes and Industrial Drives – Early fault detection in mechanical power transmission systems.

• OEM Machinery – Integrated into machinery by equipment manufacturers for condition monitoring.

Its robust construction and temperature tolerance make it ideal for installation in hazardous, high-vibration, and oil-contaminated environments commonly found in petrochemical, power generation, and heavy manufacturing sectors.

Product Advantages

• High-Temperature Resilience: Operates up to +180°C without signal degradation.

• Excellent Linearity and Sensitivity: Ensures precise, stable output across the full measuring range.

• Non-Contact Design: Minimizes mechanical wear, extending service life and reducing maintenance needs.

• Modular Compatibility: Works with various Epro converter models (e.g., CON021, CON041).

• Rugged Design: IP65-rated, making it suitable for dusty, wet, or contaminated environments.

• Customizable: Available with optional cable lengths, thread types, and certifications.

• CE and ATEX Compliance: Safe for use in industrial and potentially explosive zones.

Frequently Asked Questions (FAQ)

1. What is the measuring principle used in the PR6423/004-000?
   It utilizes the eddy current principle to detect non-contact displacement in conductive materials.

2. Can the PR6423/004-000 be used in high-temperature environments?
   Yes, the probe is designed to function reliably in environments up to +180°C.

3. Is the probe compatible with all Epro converters?
   It is compatible with most, including CON021 and CON041, depending on signal conditioning requirements.

4. What is the standard thread size for mounting this probe?
   It comes with an M10x1 thread; other thread sizes can be requested.

5. Does the sensor require recalibration in the field?
   No, factory calibration is provided and field recalibration is generally unnecessary unless conditions change.

6. What is the IP rating of the sensor?
   The probe is rated IP65, offering solid protection against dust and water ingress.

7. How long is the probe cable?
   The cable is sold separately, usually in 5 m or 10 m lengths.

8. What are the main differences between the PR6423/004-000 and PR6423/002-030?
   While both are 8mm probes, the PR6423/004-000 is optimized for higher accuracy and cleaner signal output in lower-noise applications.

9. Can this probe be installed horizontally and vertically?
   Yes, orientation depends on the axis of the vibration or displacement you wish to monitor.

10. What materials are recommended as targets for measurement?
    Best performance is achieved with ferromagnetic metals such as AISI 4140 and 4340.
