Product Introduction
The Epro PR9268/201-100 Electrodynamic Velocity Sensor is an industrial-grade sensor designed to measure vibration velocity with outstanding accuracy and durability. It belongs to the well-known PR9268 family by Epro, a brand recognized worldwide for delivering reliable and high-quality vibration monitoring solutions for rotating machinery.
Utilizing an electrodynamic measuring principle, the PR9268/201-100 generates a voltage signal directly proportional to the velocity of the vibration. This allows engineers and maintenance professionals to monitor the condition of machinery and detect early signs of mechanical failure, misalignment, or imbalance. The sensor is specifically engineered to operate effectively in harsh industrial environments, including areas with high temperatures, oil mist, moisture, or dust.
Its rugged stainless-steel construction, excellent frequency response, and simple installation make the PR9268/201-100 a preferred choice in industries such as oil & gas, chemical processing, power generation, steel production, and marine applications.
