Epro PR6423/004-031-CN 8mm Eddy Current Probe Sensor Unit

Product Overview

The Epro PR6423/004-031-CN is an 8 mm eddy-current proximity probe engineered for high-accuracy, non-contact monitoring of shaft displacement, vibration, and dynamic position in rotating machinery. It is designed for integration with external signal conditioners (such as CON021 / CON031 / CON041 systems), making it suitable for continuous condition monitoring in critical rotating assets.

The probe operates on the eddy-current principle, enabling precise measurement of conductive target movement without physical contact, eliminating mechanical wear and ensuring long-term measurement stability.

Technical Specifications

Performance Characteristics

• Non-contact eddy-current technology eliminates mechanical friction and wear

Compatible systems include:

• Epro CON021 / CON031 / CON041 signal conditioners

• Turbine condition monitoring platforms

• Vibration protection systems for rotating machinery

Application Areas

• Steam and gas turbines

• Centrifugal compressors

• Industrial motors and generators

• Pump and gearbox monitoring systems

• Condition-based maintenance (CBM) platforms

FAQ

Q1: Can the PR6423/004-031-CN be connected directly to a PLC?
No. The probe requires a signal converter (such as CON041) to convert raw eddy-current signals into PLC-compatible outputs.

Q2: What is the typical measurement gap?
The probe typically operates within a linear range of approximately 0–2 mm, depending on calibration and target material.

Q3: Is the sensor suitable for high-temperature environments?
Yes. The probe supports up to +100 °C, while the cable can withstand up to +150 °C depending on configuration.
