Product Description
The Epro PR6424/006-030 is a high-precision 16 mm non-contact eddy current sensor designed to monitor the dynamic behavior of rotating machinery. It is widely utilized for measuring radial and axial shaft displacement, position, eccentricity, and rotational speed in critical applications such as gas turbines, steam turbines, hydro turbines, compressors, pumps, and fans. Its robust stainless steel construction and PTFE-insulated cable make it well-suited for harsh industrial environments.
With a sensitivity of 4 V/mm and high linearity (≤ ±1.5%), the sensor ensures accurate, stable performance across various operating conditions. Its compatibility with multiple hazardous area classifications (ATEX, IEC-Ex, CSA) makes it ideal for safety-critical environments.
