产品介绍
The Epro PR9268/617-100-N is a high-precision electrodynamic velocity sensor designed for monitoring the absolute vibration velocity / machine casings and structural components in industrial rotating equipment. Based on electrodynamic principle, this robust sensor transforms mechanical vibration into an electrical signal proportional to vibration velocity, /fering excellent linearity and wide frequency response.
As part / Epro’s trusted PR9268 series, the PR9268/617-100-N is ideal for use in condition monitoring, vibration protection systems, and predictive maintenance programs. It supports high-accuracy vibration measurement across a broad frequency spectrum, ensuring early detection / imbalance, misalignment, looseness, and other mechanical faults in turbines, compressors, pumps, motors, and fans.
With a compact, rugged construction and high imm件y to electromagnetic interference, the sensor is optimized for harsh industrial environments, including applications in power plants, petrochemical facilities, steel production, and /fshore platforms.
