Product Description
The Epro PR6424/000-010 is a precision-engineered non-contact eddy current sensor designed for use in demanding industrial environments, especially in turbomachinery monitoring. The sensor is ideal for monitoring the radial and axial dynamic displacement, shaft position, eccentricity, and rotational speed in machinery such as steam turbines, gas turbines, hydro turbines, compressors, pumps, and fans. This sensor ensures reliable performance in extreme conditions, helping users comply with international standards like API 670.
The 16mm sensor head provides superior sensitivity and stable long-term performance, backed by rugged materials and wide compatibility with machinery monitoring systems.
