The Bently Nevada 330500-01-CN Velomitor Piezo-velocity Sensor measures casing or structural vibration in industrial machinery. It operates on the piezoelectric effect, converting mechanical motion into an electrical signal proportional to velocity. The sensor provides a 4-20 mA output for direct integration with the Bently Nevada 3500 System, enabling continuous condition monitoring. Its ruggedized housing ensures stable performance in high-vibration environments. Designed for permanent installation, it eliminates the need for periodic recalibration.
