PR6423/010-010-CN EPRO Eddy Current Displacement Sensor

Product Overview

The PR6423/010-010-CN EPRO Eddy Current Displacement Sensor is designed for non-contact measurement in industrial machinery protection and condition monitoring applications. As part of the EPRO PR6423 sensor family from Emerson, it helps monitor shaft displacement, relative vibration, position, eccentricity, and speed in critical rotating equipment.

Using eddy current technology, the sensor detects changes in the distance between its sensing tip and a conductive metal target. The resulting measurement signal can be processed by a compatible signal converter and connected to a suitable machinery monitoring system.

The PR6423 series is widely associated with applications involving steam turbines, gas turbines, hydro turbines, centrifugal compressors, pumps, fans, and gearboxes. Its non-contact measurement principle supports continuous monitoring without mechanical contact between the probe and the rotating shaft.

For replacement projects, verify the complete model suffix, cable assembly, connector, and compatible converter before ordering.

Key Features

1. Non-Contact Measurement

The eddy current sensing principle enables displacement measurement without physical contact with the rotating shaft, helping minimize mechanical wear during normal operation.

2. Accurate Shaft Displacement Monitoring

The PR6423 sensor family supports measurement of radial and axial shaft dynamic displacement, position, eccentricity, and speed when installed in an appropriate monitoring configuration.

3. Designed for Industrial Machinery

The sensor is suitable for demanding applications involving critical rotating machinery in power generation, oil and gas, petrochemical processing, and industrial manufacturing.

4. Continuous Condition Monitoring

When integrated with compatible signal conditioning and monitoring equipment, the sensor provides measurement data that can help operators assess machine condition and identify abnormal shaft movement.

5. Compatible Signal Conditioning

The probe must be paired with a compatible EPRO signal converter. The complete probe, cable, and converter configuration should be checked before commissioning or replacement.

Typical Applications

The PR6423/010-010-CN eddy current displacement sensor is suitable for applications such as:

Power Generation

• Steam turbine shaft displacement monitoring
• Gas turbine vibration monitoring
• Hydro turbine and generator monitoring

Oil and Gas

• Centrifugal compressor monitoring
• Critical rotating equipment protection
• Process machinery condition monitoring

Industrial Manufacturing

• Pump and fan shaft monitoring
• Gearbox condition monitoring
• High-speed rotating machinery diagnostics

Working Principle

The PR6423/010-010-CN operates using the eddy current measurement principle. The probe generates an electromagnetic field near a conductive target. Changes in the distance between the sensor tip and the target affect the probe’s electrical response.

A compatible signal converter processes the probe signal and provides an electrical output corresponding to displacement within the calibrated measurement range. This signal can then be used by a suitable machinery monitoring system to track shaft movement and analyze machine operating conditions.

Correct probe installation, target material, initial gap, cable configuration, and calibration are essential for reliable measurements.

Installation and Compatibility

Before installing or replacing the PR6423/010-010-CN, verify the following:

• Exact sensor model and suffix
• Probe mounting thread and dimensions
• Required cable length and connector type
• Compatible EPRO signal converter
• Target material and installation gap
• Monitoring system input and calibration requirements

Do not assume that probes and converters from different configurations are interchangeable. Confirm compatibility using the manufacturer’s documentation.
