Emerson epro PR6424/01 Eddy Current Displacement Sensor

Product Overview

The Emerson epro PR6424/01 is a high-precision, non-contact eddy current sensor designed for critical turbomachinery protection. With its 12mm tip diameter, this sensor provides a wider linear measuring range compared to standard 8mm probes, making it the ideal choice for monitoring axial thrust position, shaft vibration, and differential expansion in large rotating equipment. We provide this sensor as 100% Brand New and Original factory-sealed hardware.

Part Number Breakdown

The PR6424 series nomenclature identifies the specific hardware configuration:

• PR6424: Series designation for 12mm tip diameter eddy current sensors (Extended Range).

• 01: Indicates the mounting and cable configuration variant (typically refers to a standard 1.0-meter cable length with armored protection).

Technical Specifications

• Sensor Tip Diameter: 12 mm.

• Measurement Principle: Non-contact eddy current.

• Linear Range: Up to 4.0 mm (approximately double the range of standard 8mm probes).

• Target Material: Ferromagnetic steel (Standard calibration for 42CrMo4 / AISI 4140).

• Frequency Response: 0 Hz (DC) to 10 kHz for static and dynamic analysis.

• Environmental Rating: IP68 hermetically sealed tip, oil-resistant construction.

Engineering Advantages

The PR6424/01 addresses the need for high-fidelity data in environments where significant shaft movement occurs. The larger 12mm tip creates a more robust electromagnetic field, allowing for a 4mm linear measurement span. This capability is essential for tracking "axial float" and thermal expansion in massive steam turbines and compressors. Its armored cable provides superior mechanical protection against sharp edges and vibration wear within bearing pedestals. By delivering sub-micron resolution without physical contact, the sensor ensures zero mechanical wear and long-term stability in high-temperature, oil-saturated conditions.

FAQs

• Why should I choose the PR6424/01 over an 8mm sensor?The PR6424/01 offers an extended linear range of 4mm. Choose this model when the expected axial movement or vibration amplitude exceeds the 2mm limit of standard 8mm sensors.

• Does this sensor require a matching driver?Yes. The PR6424/01 must be connected to an epro signal converter or driver (such as the CON 021 or MMS 6000 series) that is specifically calibrated for 12mm sensors.

• Can the armored cable be shortened?No. Never cut or shorten the integrated cable. Eddy current measurement systems are electrically tuned to a specific total length. Altering the cable length will void the calibration and result in inaccurate readings.

• What mounting thread does the PR6424/01 typically use?The standard mounting for this series is usually M14x1.5. Ensure your bearing housing or mounting bracket is correctly tapped to provide a rigid, vibration-free base for the sensor.
