مقدمة المنتج
The Epro PR9268/617-100 is a high-performance electrodynamic velocity sensor designed for monitoring the absolute vibration velocity من machine housings, bearing pedestals, and structural components. It plays a critical role in preventive and predictive maintenance strategies by helping detect early signs من mechanical degradation, imbalance, or misalignment.
This sensor operates on the principle من electromagnetic induction. Internal movement من a seismic mass within a magnetic field produces a voltage proportional to the velocity من the sensor body. With a robust housing and reliable mechanical design, the PR9268/617-100 is ideal for industrial environments where durability, signal fidelity, and ease من installation are essential.
