产品介绍
The Epro PR9268/617-100 is a high-performance electrodynamic velocity sensor designed for monitoring the absolute vibration velocity / machine housings, bearing pedestals, and structural components. It plays a critical role in preventive and predictive maintenance strategies by helping detect early signs / mechanical degradation, imbalance, or misalignment.
This sensor operates on the principle / electromagnetic induction. Internal movement / a seismic mass within a magnetic field produces a voltage proportional to the velocity / 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 / installation are essential.
