Applications
The Epro PR6424/101-121 is widely used in machinery condition monitoring systems where precise and continuous shaft displacement measurement is required for safe and reliable operation.
It is commonly applied in steam turbines, gas turbines, hydro turbines, compressors, pumps, and large industrial rotating equipment. In turbine applications, it provides continuous monitoring of radial shaft vibration and axial displacement. In compressor and pump systems, it supports early detection of mechanical issues such as imbalance, misalignment, rotor instability, and bearing wear.
It is also widely used in API 670-compliant machinery protection systems, where real-time vibration data is essential for preventing equipment damage and ensuring stable operation of critical rotating assets in power generation, oil and gas, and petrochemical industries.
Advantages
This sensor is engineered for high accuracy, long-term stability, and reliable performance in harsh industrial environments.
It provides non-contact eddy current measurement with high linearity, ensuring precise displacement tracking even under high-speed rotating conditions. The 16mm probe head creates a stable electromagnetic field for consistent measurement across varying shaft conditions.
It is designed with strong resistance to temperature variation, vibration, and electromagnetic interference, making it suitable for continuous industrial operation. Low drift characteristics help maintain calibration stability over long periods, reducing maintenance requirements and improving system availability.
