Applications
The Epro PR6424/103-021 is used in high-reliability rotating machinery systems where continuous and accurate shaft displacement monitoring is required for protection and predictive maintenance.
It is commonly applied in steam turbines, gas turbines, hydro turbines, centrifugal compressors, pumps, and heavy industrial rotating equipment. In turbine applications, it enables real-time monitoring of radial vibration and axial shaft position. In compressors and pump systems, it supports early detection of mechanical issues such as misalignment, imbalance, rotor instability, and bearing wear.
It is also widely implemented in power generation, oil and gas, and petrochemical facilities where API 670-compliant machinery protection systems require continuous vibration data to ensure safe and stable operation of critical assets.
Advantages
This sensor uses eddy current technology to provide accurate non-contact displacement measurement without mechanical contact or wear.
It delivers stable linear output response, making it suitable for high-speed rotating machinery. The 16mm probe design ensures a stable electromagnetic field distribution, improving measurement consistency across varying shaft conditions.
The PR6424 series is engineered for harsh industrial environments, offering strong resistance to temperature variation, vibration, and electromagnetic interference. Its low drift characteristics support long-term calibration stability, reducing maintenance frequency and improving system uptime in continuous operation environments.
