Product Introduction
The Epro PR9268/602-000 is a robust and reliable electrodynamic velocity sensor designed specifically for vibration monitoring in industrial rotating machinery. This sensor is part of the trusted PR9268 series by Epro, a brand known for high-quality condition monitoring solutions tailored for demanding environments.
As a velocity transducer, the PR9268/602-000 converts mechanical vibrations directly into an electrical voltage signal, which is proportional to the velocity of the movement. The rugged design ensures long-term performance even under severe operating conditions such as those found in power generation, steel processing, pulp & paper, and petrochemical industries.
This sensor is suitable for both OEM installations and retrofit projects where high sensitivity and broad frequency response are essential. It integrates seamlessly with monitoring systems like the Epro MMS series or other industrial vibration measurement platforms.
