Based on the search results, the EPRO PR6423-003-010 is an eddy current sensor designed for industrial vibration and displacement monitoring. Below is a technical overview of its key features and specifications:

Product Overview

The PR6423-003-010 is a non-contact eddy current sensor used primarily in turbine supervisory systems (TSI) for measuring axial/radial vibration, shaft displacement, and dynamic movement in rotating machinery. It consists of three components: sensor probe, extension cable, and preamplifier (e.g., CON021). The sensor operates on electromagnetic induction principles, converting proximity changes into voltage signals for real-time monitoring 147.

Key Specifications

Feature Description

Model Code 003: Thread length 65 mm; 010: 5 m unarmored cable + mid-connector 10

Thread Size Metric: M10×1 or Imperial: 3/8"-24UNF (selectable during ordering) 46

Measurement Range 2 mm linear range (standard for 8 mm probe diameter) 47

Cable Options Unarmored cable; 1 m mid-connector for easy installation 10

Operating Temp. -35°C to +380°C (suitable for high-temperature environments) 19

Calibration Factory-calibrated with 42CrMo4 steel (SAE 4140); no on-site recalibration needed 19

Preamplifier Compatible with CON021 (standard) or CON011 (explosion-proof) 46

Design and Functionality

Eddy Current Principle

Generates an oscillating magnetic field; amplitude attenuation correlates with probe-to-target distance 19.

Outputs -1 to -22 V DC linear voltage proportional to gap changes 57.

Robust Construction

Stainless steel probe with customizable thread lengths (25–115 mm) for flexible mounting 10.

IP67-rated connectors (optional) for dust/water resistance 6.

Installation Requirements

Target surface diameter must exceed 1.5× probe head diameter (flat surfaces) or 3× (shafts) to maintain sensitivity 3.

Requires precise air gap adjustment via threaded mounting
