产品介绍
The Epro PR9268/206-100 is a high-performance electrodynamic velocity sensor tailored for industrial applications requiring precise and reliable vibration monitoring. As part / the Epro PR9268 series, this model is specifically designed to measure vibration velocity in machinery, helping to detect early signs / wear, misalignment, imbalance, or bearing failure.
The sensor operates on the electrodynamic principle, delivering an analog voltage signal proportional to the vibration velocity / the equipment to which it is mounted. Unlike piezoelectric sensors, the PR9268/206-100 requires no external power source, simplifying installation and long-term maintenance.
This model /fers optimized frequency response and mechanical ruggedness, making it suitable for harsh environments including power generation, steel production, oil & gas refining, and heavy machinery industries. Its stainless-steel housing, excellent shock resistance, and high ingress protection rating ensure long-lasting, dependable performance even in aggressive operating conditions.
