Applications
The Epro PR6424 series 16mm eddy current sensor is widely used in turbomachinery condition monitoring systems where precise measurement of shaft dynamic behavior is required.
It is commonly applied in steam turbines, gas turbines, hydro turbines, compressors, pumps, and industrial fans. 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 faults such as imbalance, misalignment, rotor instability, and bearing wear.
It is also widely used in high-reliability protection systems where continuous real-time vibration data is required to ensure safe operating conditions and prevent equipment damage.
Advantages
This sensor is engineered for high accuracy, long-term stability, and robust industrial performance.
It delivers non-contact eddy current measurement with excellent linearity, ensuring precise displacement and vibration tracking even under high-speed rotation. The 16mm probe design provides a balanced sensing field suitable for a wide range of shaft sizes in medium and large rotating machinery.
It is designed with strong resistance to temperature variation, vibration, and electromagnetic interference, making it suitable for continuous operation in harsh industrial environments such as power plants and petrochemical facilities. Low drift characteristics support long calibration intervals and stable long-term monitoring performance.
