مقدمة المنتج
The Epro PR9268/617-100-N is a high-precision electrodynamic velocity sensor designed for monitoring the absolute vibration velocity من 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, منfering excellent linearity and wide frequency response.
As part من 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 من imbalance, misalignment, looseness, and other mechanical faults in turbines, compressors, pumps, motors, and fans.
With a compact, rugged construction and high immوحدةy to electromagnetic interference, the sensor is optimized for harsh industrial environments, including applications in power plants, petrochemical facilities, steel production, and منfshore platforms.
