Applications
The Epro PR6424/102-101 is widely used in turbomachinery condition monitoring systems where precise real-time displacement measurement is required for protection and predictive maintenance.
It is commonly applied in steam turbines, gas turbines, hydro turbines, compressors, pumps, and large industrial rotating equipment. In turbine systems, it enables continuous monitoring of radial shaft vibration and axial displacement. In compressor and pump applications, it supports early detection of mechanical issues such as misalignment, imbalance, rotor instability, and bearing wear.
It is also widely used in API 670-compliant machinery protection systems, where continuous vibration data is essential to ensure safe operation of critical rotating assets in power generation, oil and gas, and petrochemical industries.
Advantages
This sensor uses eddy current technology to achieve accurate non-contact displacement measurement without mechanical wear.
It delivers high linearity and stable output performance, making it suitable for high-speed rotating machinery. The 16mm probe geometry ensures a stable electromagnetic field distribution, supporting consistent measurement across varying shaft conditions.
The PR6424 series is designed for industrial durability, with strong resistance to temperature variation, vibration, and electromagnetic interference. According to manufacturer specifications for the PR6424 family, long-term drift is typically very low, supporting stable calibration and reduced maintenance in continuous monitoring systems.
