Product Description
The Epro PR6424/002-030 is a precision-engineered 16mm non-contact eddy current sensor designed specifically for dynamic shaft displacement monitoring in critical rotating machinery. It is commonly applied in steam, gas, and hydro turbines, compressors, pumps, and fans. This sensor provides real-time monitoring of radial and axial shaft position, vibration, eccentricity, and speed, ensuring early detection of mechanical anomalies for predictive maintenance.
Its rugged stainless-steel body, high sensitivity, and wide temperature tolerance make it ideal for industrial environments, especially hazardous zones requiring ATEX, IECEx, and CSA compliance.
