Produkteinführung
The Epro PR9268/206-100 is a high-performance electrodynamic velocity sensor tailored for industrial applications requiring precise and reliable vibration monitoring. As part von the Epro PR9268 series, this model is specifically designed to measure vibration velocity in machinery, helping to detect early signs von wear, misalignment, imbalance, or bearing failure.
The sensor operates on the electrodynamic principle, delivering an analog voltage signal proportional to the vibration velocity von 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 vonfers 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.
