Applications
The Epro PR6424/101-021 is widely used in turbomachinery condition monitoring systems where accurate real-time displacement measurement is required for machinery protection and predictive maintenance.
It is commonly applied in steam turbines, gas turbines, hydro turbines, compressors, pumps, and large industrial fans. In turbine systems, it enables continuous monitoring of radial shaft vibration and axial displacement. In compressor and pump systems, 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 real-time vibration data is essential to ensure safe operation of critical rotating assets in power generation, oil and gas, and petrochemical industries.
Advantages
